One, image unit can automatically identify the numeral of car plate, letter, chinese character real-time and accurately, and directly gives recognition result.Simultaneously manager can also by candid photograph to picture recognition go out vehicle characteristics, such as vehicle, color etc..Three-dimensional high definition Car license recognition video camera uses mega pixel high definition identification technology, can use under outdoor adverse circumstances, reliable and stable.H.264, the real-time code stream of MPEG4, MJPEG three-dimensional high definition Car license recognition, can off-line working, it is provided that, in conjunction with high performance video compression algorithm, makes picture transfer more smooth.Three-dimensional high definition Car license recognition video camera debugging can complete in conjunction with IE browser, simple to operation, can realize not parking current.

Integration: three-dimensional high definition Car license recognition video camera has been internally integrated required hardware and software, and the equipment being not required to auxiliary can complete its function.The version of integration make three-dimensional high definition Car license recognition video camera add system adaptability, stability, facilitate installation, debug and safeguard.

Embedded: inside three-dimensional high definition Car license recognition video camera, all algorithms to be solidificated among hardware, therefore can realize working alone with divorced from computer, obtain broader practice space.

Car license recognition: the license board information of the vehicle that comes in and goes out is investigated by three-dimensional high definition Vehicle License Plate Recognition System as the unique of vehicle management, automatically the image of the vehicle that comes in and goes out is captured, automatically license board information is identified, by the recognition result comparison of the vehicle that comes in and goes out is judged whether vehicle is effective vehicle.

Being restricted by site environment, car plate surface and pickup axis cannot accomplish vertically, to cause car plate to be distorted, and the position character away from video camera diminishes, and cause certain difficulty to identifying.Three-dimensional high definition Car license recognition distortion of camera calibration algorithm uses multicolour space to carry out car plate background color detection, it is accurately positioned license plate area, obtaining license plate sloped angle and transversely deforming ratio, maximum tilt angle reaches 25 °, and the interior accurate alignment rate of security standpoint 15 ° reaches more than 99%.

Two, image unit is in the networking work of each gateway, host computer recognition method networked fee collection, and carries out the management of vehicle using license plate number as unique Data Identification.By the comparison of the image unit recognition result of each gateway is judged and charged, down time and Parking Fee are calculated and be shown on the management program interface of sentry box terminal according to corresponding toll project；

Owing to whole system is network structure, for fixing vehicle, suspension is not have influential, because the license plate number of fixing vehicle all has been downloaded in image unit, internal is solidificated among hardware by all algorithms." embedded " recognition method supports that divorced from computer realizes working alone.

For interim vehicle, if there is no suspension between the equipment at a crossing, do not affect；Only entering when this interim car entrance from A crossing, the outlet from B crossing goes out again, and central server is in offline condition, just can affect the toll administration to this interim vehicle；Image unit can store 500 photos, 20,000 identification records with off line.

Can also configure " bar code printer " and " bar code scan rifle " in sentry box terminal, when central server suspension, sentry box terminal program can remind staff to use " bar code printer " that interim vehicle is sent out a bar code, and bar code have recorded entry time；

When so this interim vehicle appears on the scene from any crossing, if " central server " " recovers networking ", 500 photos of storage, 20,000 identification records can be uploaded, then current by " interim car Car license recognition toll administration rule "；

When this interim vehicle appears on the scene from any crossing, if " central server " does not also have " recovering networking ", staff can ask for bar code to this interim car, current by " interim car bar code recognition toll administration rule "；

Without blocking the parking lot that comes in and goes out, the charge of interim car: for certain megastore, fixing (internal car) vehicle and interim vehicle are shared same outlet or entrance carries out networking unified management.

The scheme that my company provides only need to install image unit, fixing vehicle at entrance and exit, can set up fixing user profile, Car license recognition Toll Free in software.Interim vehicle is divided into three types, A general user to use the scale fee in parking lot, market to perform;User can be implemented preferential strategy " the most preferential " " preferential by the amount of money " by B market, has " inputting preferential " button on the software of outlet sentry box, as long as need preferential vehicle, security personnel, press " inputting preferential " and can carry out charge process；C " bar code printer " and " bar code scan rifle " can also tackle the interim vehicle of " without car plate " or " car plate is difficult to identification ", unlicensed vehicle uses entrance to send out receipt, exit scanner carries out barcode scanning to receipt during admission, thus the down time of calculating vehicle, calculate the toll amount of vehicle.Fixing user and casual user are to fix user or casual user by Car license recognition automatic decision car plate.

Being identified result when vehicle admission and the information of vehicles that be will identify that by TCP/IP network is sent to parking lot and respectively exports, recognition result and Back ground Information are shown by outlet

Gateway monitors in real time: demonstrate the monitoring image of entrance in the program of system sentry box in real time, makes the management in parking lot be formed conveniently, and safety controls system efficiently.

Outlet automatic charging: this function must assure that the unimpeded of network, gateway, parking lot equipment real-time online, it is mainly used at gateway, parking lot installing the parking charge system of " three-dimensional high definition Car license recognition video camera ", pass through toll collection system software, the result of identification is passed to outlet by " the three-dimensional high definition Car license recognition video camera " of porch, the image unit in exit is identified result and automatically calculates the toll amount that should pay according to toll project, prevent internal work personnel from practising fraud, effectively avoid the loss of account due.

Data programming count and car plate fuzzy query: this function must assure that the unimpeded of network, gateway, parking lot equipment real-time online, can be used at any time add up toll amount, carries out the fuzzy query of car plate.

License plate image mates:

1, identical car plate

Identical car plate directly mates, the image results that sentry box program " exit passageway " is mated with the display of " corresponding admission " window.

2, approximation car plate

The Car license recognition caused such as (heavy rain, severe snow, foggy weather etc.) under the influence of objective condition completely does not mates, the approximation license board information bar being automatically list is entered below field picture in correspondence, management personnel can manually search the similar car plate that system does not identify, approximation license board information bar is quickly found out the car plate of correspondence, carries out car plate coupling.The manpower comparing safety to ensureing vehicle is carried out for management personnel.

3, unlicensed vehicle

When unlicensed vehicle admission, vehicle triggers ground induction coil when entering gate area, parking lot, " three-dimensional high definition Car license recognition video camera " captures the image of vehicle automatically, and information of vehicles is reached the unlicensed vehicle database of service centre, display is in sentry box Program Screen unlicensed car information bar, and management personnel manually can recall the information of this car correspondence admission according to vehicle image.The manpower comparing safety to ensureing vehicle is carried out for management personnel.

Note: our company is to ensure that the charge of unlicensed vehicle is accurate, save the artificial speed searched, increase " bar code printer " and " bar code scan rifle " simultaneously is done miscellaneous function and is used entrance to send out receipt, exit scanner carries out barcode scanning to receipt during admission, thus the down time of calculating vehicle, calculate the toll amount of vehicle.

System management function is realized by managing computer.

System uses full networked design, in order to ensure the reliability of system, it is necessary to assure the safety of network and unimpeded.Use the mode of network to realize the transmission of data and image between " three-dimensional high definition Car license recognition video camera " and the control management computer of gateway.

Three, operation principle

Temporary subscriber vehicle:

When vehicle is marched into the arena, vehicle sails Car license recognition video capture region into, trigger ground induction coil, image unit is automatically captured the image of admission vehicle and automatically identifies license plate number, be recorded into field time and information of vehicles is reached service centre, searching database draws class of vehicle, display is in the center screen of sentry box, and management personnel can monitor the vehicle condition of entrance, and recoverable recognition result at any time.Display screen shows that the effect duration of this car or parking space information show, welcome signal language of Denging.

When vehicle appears on the scene, vehicle sails Car license recognition video capture region into, trigger ground induction coil, image unit is automatically captured the image of admission vehicle and automatically identifies license plate number, information of vehicles is also reached service centre by the record time for competiton, service centre is according to comparison automatic decision vehicle character, and programming count recalls relevant information and shows.When vehicle appears on the scene, the admission information of this vehicle is shown on the computer screen of sentry box by system, and the toll project formulated according to software carries out the statistics of toll amount, for management personnel's management to interim vehicle.

Fixed client vehicle:

Installing image unit at entrance and exit, the license board information of corresponding authorised channel is downloaded in image unit by management computer.Feel the license board information sent out three-dimensional high definition Car license recognition video capture, identify, process vehicle with needing when vehicle sails or roll away from parking lot into, and be sent to manage computer by recognition result, management computer utilizes recognition result to inquire about data base, if video camera disconnects with management computer, video camera with off-line working, can not result in the blocking of wagon flow and reaches not parking current.

Whole parking system carries out management centre computer centralized management, and use three-dimensional high definition Car license recognition video camera that the vehicle entering parking lot is carried out video capture, automatically identify, vehicle is guided to enter the region that parking lot is specified, at EXIT solid high definition Car license recognition video camera, the vehicle rolling parking lot away from is identified, clearance automatic for fixed client, for temporary subscriber according to parking time charge, can leave after payment, management centre computer carries out unified management to whole parking lot, the management making parking lot is formed conveniently, safety, control system efficiently.

Banister uses advanced DC Frequency Conversion Technology, argues for the sake of arguing and the bar speed that falls can be with independent regulation, it is possible to achieve argue for the sake of arguing at a high speed, it is achieved fast passing；Fall at a slow speed bar, prevents from pounding car, pounding people, safer, it is to avoid traditional banister identical high speed caused of bar speed of arguing for the sake of arguing is dangerous, the defect that low speed is inconvenient.

Parking lot management software is mainly made up of SQL Server data base, service centre, management program, outlet sentry box program, entrance sentry box program and relevant hardware devices, the owner that can realize car discrepancy parking lot this car plate of automatic decision is fixing user or casual user, according to fees policy computational costs and open a sluice gate to let pass, it is achieved not parking current.

1, service centre: mainly receive the picture of all video cameras, receives the record of access road, downloads the communication functions such as car plate.Note: service centre must be with SQL Server data base on same computer.

2, management program: carry out car plate, passage, authority, toll project etc. and arrange, the various form of query statistic.

3, outlet sentry box charging program: receive the record of exit passageway, display outlet picture, search corresponding entrance picture, entry time, calculate the time of staying and expense, charge；Can at most monitor an entrance picture, remote switching-off.

4, entrance sentry box monitoring programme: monitor the picture of multiple entrance, and car plate, remote switching-off can be revised.

Financial payment field, the Internet, EPC traffic payment system:

EPC(Electronic Picture-catching Collecting) i.e. pay capturing system by mails.Refer to that vehicle is when by charge station, realize vehicle identification, information write (entrance) by vehicle identification system and automatically spatially deduct corresponding fund (outlet) from the Hart payment bound in advance, being a kind of E-payment system for the management of road, bridge, tunnel and parking lot based on HIEP agreement.

Paying capturing system (EPC) by mails is the most state-of-the-art Fare Collection System, is one of the service function of intelligent transportation system, need not stop when vehicular traffic is by road junctions such as highway, bridge, tunnels, be i.e. capable of testing vehicle register automatically identify, automatic fee.In parking lot manages, for improving gateway vehicle pass-through efficiency, build unattended express passway, exempt from card taking, not parking discrepancy experience, just changing the management mode in the parking lot that comes in and goes out.

In conjunction with in HIEP, http communication agreement, pass through WEB service, it is achieved the technology that vehicle electric pays.

Based on HIEP(HTB Internet E-wallet Protocol) Hart pay space EPC(Electronic Picture-catching Collecting) design and realization.

Hart pays space and is applied to HTML(data outward appearance display internet standard protocol), it has a set of rule of conduct being related to interface, including global naming with quote, register, communicate, information processing, life cycle etc.；In the entire system, we have employed the mode that B/S framework WEB remotely monitors, by the cross-platform of JAVA language and the characteristic of network programming thereof, long-range control method with JNI and SOCKET programming, the method using programming realizes the long-range control to the monitor node in wide area network, enables the host to realize the monitoring to remote equipment.Design and develop process based on three-decker distributed system；And with compressor long-distance monitoring system as background, use the technology such as DCOM, ActiveX and remote scripting, it is achieved an EPC specifically uses.

The realization that 1.WEB remotely controls

1.1 remotely control machine (bank preposing transaction system) and the interconnection of on-site monitoring equipment

On the basis of existing LAN, the interacted system of composition is as shown in Figure 1, it is achieved remotely control, then by a Monitor and Control System based on arrowband multiple protocol environment.Adapt to bandwidth by frame per second self-adjusting, and the data relying on protocol gateway to carry out between IPX and TCP/IP exchange, it is achieved remotely monitor.

SHAPE * MERGEFORMAT SSClient first create a client Socket object, be connected with the service routine operating in host port 10000, attention port should be greater than 1024, in order to avoid clashing with the port numbers of system；The IP address of main frame has host variable to determine, around the inlet flow of BufferedReader and the output stream of PrintWriter, character string is written and read operation, interacts with other programs for order and the parameter that server is transmitted through.Exception catching is carried out with try catch statement in whole program segment.

The programming of server end should adapt with the establishment of client-side program.Owing to a long-range control machine can control multiple on-site monitoring equipment, so server program must use multi-thread mechanism, this is also a big characteristic of Java language.

This program segment is made up of two classes: main classes and thread class.Main classes is responsible for setting up server socket ServerSocket, and port numbers must be consistent with the port numbers of client computer, is then created the communication of a sockets interface, special disposal and client computer by the accept method of ServerSocket；Thread class, for creating a new thread, is responsible for processing the input of each on-site monitoring equipment and output request.Certainly each client can also use different port numbers to send request to server, and the client that server the most also creates the thread of different port number consistent with port numbers communicates.

Long-range control host machine server program must have and carries out the ability of dynamic interaction with data base.Data base deposits substantial amounts of field data and controls parameter and the order etc. of execute-in-place.A certain thread body in server program is responsible for the access of data base, is revised and the operation such as maintenance, and Java language realizes the connection with data base by JDBC；Make Java language can access data base by driver.

1.2 JNI implement

The control of monitor node can only be used third party's language to carry out by Java language, such as C or assembler language.Write owing to controlling the communications portion Java language of machine, for realizing the control to monitor node, the JNI technology of Java language just can realize combining flawlessly with C and C Plus Plus, although this sacrifices transplantability to a certain extent, but enable Java language and concrete environment come into contacts with, possess the ability driving hardware.In the example that native system realizes, the application of EPC and driver C language is developed, and the program that C language worked out in Java language makes nation method body.Thus realize the control of native system.

The driver of monitor node is shown a C language, the C built-in function of the function major part Shi Yanhua company exploitation employed in program, utilize these built-in functions to drive monitoring device to complete various function.These procedure sets are become Java nation method body, becomes the key technology realizing remotely control with Java language.

For controlling machine, utilize the integrated nation method of Java.

This section of program is made up of main classes and nation method class, and main classes is in addition to the program completing communications portion, it is necessary to instantiation nation method class, and calls nation method；When defining nation method class, key word native must be added, and program segment has one section of static code, this static code is that nation method class loads drive storehouse by system function, go to obtain the data in monitor node or data acquisition unit by the execution of nation method again, pass to data server.

So far, the code of remote monitoring equipment achieves the most substantially, its Socket service device mainly including operating in control machine one end and nation method application, having server to monitor from far-end (Browser) and send " RUN " order come, Socket service device recalls according to " RUN " order transmitted and is operated accordingly by the EXE programme-control of nation method or runtime server end.In data acquisition is applied, JNI method is used to be directly inserted into background data base reading the data gathered, then JDBC is used to access database displaying at Browse end, owing to system must first drive reading data, multi-threaded approach is used to realize time delay, it is ensured that can show at Browse end after data have been transmitted.For other embedded system such as monitoring system, equally use the communication mechanism of the integrated of nation method and Socket network, effectively control machine and distance host are coupled together by network, to realize remotely controlling.

Send different command road servo driver end by bottom Socket communication mechanism and carry out the process of correspondence.Platform-neutral due to Java language so that Java with nation method integrated in conceal substantial amounts of ins and outs.

2. the design of system

2.1 for EPC front platform industry long distance control system, the structure of system design as shown in Figure 2 SHAPE * MERGEFORMAT

Due to history, monitoring device can not directly and information network carries out communication, so in the design process of system, adding industry control station between intermediate layer and monitoring device layer, as the data service layer of three-decker.

Such design structure is so that the exploitation of intermediate layer and expression layer is totally independent of particular type and the structure of industry control network, and industry control stands in the effect serving intelligent gateway in industry control network and the connection of information network, shields industrial control network.It is thus possible to play the three layers of C/S structure various advantages in Internet/Intranet applies completely.

The key technology that 2.2 systems realize

According to above design architecture, with compressor long-distance monitoring system as example, this system realizes distributed three layer structure, and the technology such as ASP, DCOM, ActiveX technology and remote scripting of having used Microsoft with B/S structure.

2.3 based on arrowband multi-protocols EPC monitoring system implementation model

System can use bandwidth to only have 64Kbps, and also needs on this channel run a small amount of data-transfer applications, thus effective bandwidth is extremely limited.User is higher to the requirement of single-frame images, adjusts to preferably carry out dynamic frame per second and two field picture, and we have employed the Motion-JPEG form of customization.It addition, user is for the safety of network, using agreement to separate mode, leading portion operates in an Internetwork Packet Exchange LAN, and far-end is then Intranet based on TCP/IP, and the data transmitted need to change between IPX and TCP/IP.So, must also one protocol gateway of construction between front-end collection and remote monitoring.5 parts can be divided into: 1 on this system physical structure) head end video equipment；2) front-end control PC；3) communication line；4) protocol gateway；5) remote controller.Whole system contain collection, compress, preserve, network transmission, the module such as long-range monitoring, structure as shown in Figure 3:

Due to this model message sink coding, decode, transmit, play back and store be all based on software realize, the parameter such as frame per second and picture reconnaissance all allows user dynamically to adjust, and certain bandwidth self-adaption can be realized by systems response, it is possible to ensure basic QoS.

2.4 Location of Vehicle License Plate algorithms

Native system is captured image for common CCD camera and is carried out topography's enhancement process, it is thus achieved that preferably vehicle license plate characteristic describes, efficient in conjunction with genetic algorithm, and quick feature meets most the regional location of vehicle license plate characteristic at full figure range searching, thus is accurately positioned car plate.1) Image semantic classification；2) topography processes；3) feature statement.

(2) design of charge system

The function of 1.EPC charge system:

In this projector operating and managing, whole EPC is calculated by EPC management of computing system and is managed by the webmaster personnel of bank preposition system (BFS), is controlled (as started, closing), the operation such as modify running parameter including all of equipment in all EPC calculating systems or the current operating state of facility and running parameter, duty to equipment or facility.EPC calculates system to calculate the user job that EPC user submits to, need between EPC user and local user, contact is set up between EPC resource and local resource, namely need EPC user is mapped as local user, EPC resource is mapped as local resource, the use of EPC resource is mapped as by EPC user local user's use to local resource.(list of references 7 " The grid:Blueprint for a New Computing Infrastructure ").Abstract EPC is calculated and is converted into concrete local computing by this series of mapping process, EPC system, by performing concrete local computing to complete abstract cloud computing, carries out concrete operation by specific transmission line and control protocol to the long-range network equipment or facility.

2.EPC charge system structure is shown in Fig. 4:

2.1 authentication modules:

Proof module to entity identities in computer EPC system.Entity includes resource or user, realizing its certification by HIEP authentification of message certificate, HIEP authentification of message is signed and issued by mechanism trusty, shows as a segment information, this segment information includes the information of certificate owner, the effective time of certificate and the digital signature of authentication module.User or resource to all access, recorded its information in accounting module.

2.2 user agent module:

When user needs to use EPC resource to carry out EPC calculating when, one computer being connected to HIEP bank preposition system of user's initial landing, and connect user agent module, then user is that he gives user agent by needing the resource information of application and calculative user job, and user agent module replaces user to complete two-way authentication, apply for resource, submit operation to, obtain the work such as result.

2.3 resource proxy modules:

When one group of resource adds EPC calculating system, Resource Manager first has to connection resource proxy module, the work that this Resource Broker is responsible for this two-way authentication organizing resource, is distributed and reclaim.Resource Broker not necessarily operates on this group node belonging to resource, but this group resource of Resource Broker and its management will be in same local trust territory.

2.4 resource distribution modules:

One process being calculated system creation by EPC, is responsible for the management work of resource, is managed a large amount of dynamic resources for convenience, simplifies the resource allocation process of complexity simultaneously.Resource distribution module sends resource requirement information to Resource Broker.The information that it is managed by all of Resource Broker issues resource distribution module, and resource updates when, the more fresh information of resource is sent to resource distribution module.The resource information received is arranged by this module, forms abstract, the resource information of logic.Therefore, resource distribution module is the core of communication for information between a module.

2.5 accounting modules:

This module record set processes user and the information of resource, authentication module joins this EPC all applications and calculates the user of system and the information write accounting module of resource, resource distribution module also writes this module the information submitting operation to after user completes to calculate, this module it is carried out record.

The realization of 3.EPC charge system

The flow process of 3.1 chargings

Resource is managed by the system that 3.1.1EPC calculates, and is allocated resource according to the situation of user, and each entity obtains the process of entity certificate；

3.1.2 user creates user agent and user agent and submits the process of user job to；

3.1.3 the calculation process of user job；

3.1.4 the release process of resource.

The design of 3.2 EPC calculating data bases and realization:

If we to manage a small-scale EPC, in accounting module data base, record user profile, resource information, user use the information of resource.It is convenient and swift that our data to be ensured store, the concordance of data to be ensured and integrity, whole charge system is made up of multiple threads, and they are by a shared drive exchange information, owing to multiple processes to access shared memory field simultaneously, the conflict of share and access will be produced.

The conventional method solving share and access conflict is to use locking mechanisms to solve, but the locking and de-locking of shared drive is inherently taken the biggest system resource, thus the performance of EPC system can be affected, therefore we are by the read-write region of each process in reasonable arrangement system, avoid two processes to revise an internal storage location, it is possible to prevent sharing conflict and be made without locking and de-locking operation simultaneously.Data form in our design database is as shown in following table 1-3:

				rescer_id	String	16	Resource credentials number, the authentication information of record resource
in_time	Timestamp	8	Resource joins the moment of cloud system
				out-time	Timestamp	8	Resource exits the moment of this cloud system

Table 3:htb user resources mapping table

Title	Type	Byte number	Implication
				htbuser_id	String	16	User ID, uses the code name of EPC user, is one of candidate key
htbres_id	String	16	Resource code name, the code name of resource in this process, is one of candidate key
				flux	Long	32	Flow when user uses resource to calculate
start_time	Timestamp	8	User begins to use the moment of resource
				end_time	Timestamp	8	User terminates to use the moment of resource
time	Time	8	Current state, is validated user or disabled user

For avoiding internal memory sharing conflict, the relation between each table as shown in Figure 5:

In order to prevent share and access conflict, we arrange different processes to write different regions, and wherein, htbuser_id, user_type are only write by user agent's process；htbres_id, res_type, In_time, out_time are only write by Resource Broker process；Usercer_id, state, rescer_id are only write by authentication processes；Flux, start_time, end_time are only write by resource distribution process.These regions only can perform write operation in a process, and other processes are read-only, so not havinging sharing conflict, ensure that the safety of data base to a certain extent.

(3) fee evasion capturing system

The first situation:

Vehicle is legal identity, uses normal payment

The second situation:

Vehicle is legal identity, but can not normally pay the fees (including resisting payment), then recorded blacklist server CRLs；

The third situation:

Vehicle is illegal identity, is forced through EPC passage, will recorded blacklist server CRLs；

In this project fee evasion capturing system be after occurring client behavior record in the case of two kinds to blacklist server.When occurring the second situation to be, this Hart the settling bank paying address automatically deducts fees or punishes；When there is the third situation, this information of vehicles being transferred traffic and processes.

In this project implementation, according to XHSI (privately owned extension HIEP authentification of message system), for providing the underlying security service supporting HIEP.HIEP extension use X.509 digital certificate provide certification and message protection.The second situation is used the mode of certificate revocation list CRL.

Here associating revocation scheme based on XHSI one-way hash chain, HIEP extension and CRLs shared model is used, its advantage is: need not the participation of CA during certificate revocation, can preferably solve single point failure and the problem of CA cross-certification, traffic congestion can be avoided and guarantee the real-time of certificate revocation.

1.HIEP extension participating certificate revocation scheme:

The situation of certificate revocation has two classes: the first kind is that the private key corresponding with PKI is lost or reveal；Equations of The Second Kind is that certificate contract may terminate, or the identity of the holder described in certificate changes or business information is revoked.The one-way hash chain that this programme uses, for above-mentioned first kind situation, it may not be necessary to the participation of CA and make certificate temporarily or permanently lose efficacy.For Equations of The Second Kind situation, it is possible to use HIEP extension and CRLs shared model realize illegal charging.

2. New Certificate based on one-way hash chain

Hash chain is based on a disclosed function H, and this function is easy to carry out forward calculating under existing computing environment but hardly possible carries out backwards calculation.If the input of one-way function is fixed length, here it is one-way Hash function (OWHF).

We are divided into multiple segment the maximum vital values of a certificate.Certificate can be expired at the end of any one time period, expired can be controlled by the owner of certificate or its manager.Certification authentication person need not obtain revocation information from CA and just be able to verify that the effectiveness of certificate.Therefore, this revocation mechanism simply safety.One-way hash chain carries out recursion by one character string to one-way Hash function of input and sets up, Hi (r)=H (Hi-1 (r)) (i=1 can be expressed as, 2 ...), here H0 (r)=r is hash chain root.

Certificate update time point is defined as: D1=D+L, D2=D+2*L ..., Dj=D+j*L, and produce one-way hash chain Hi (r)=H (Hi-1 (r)) (i=1,2, ... j), H0 (r)=r and r is a random number being only known to user U.End user sends request (PK1, D, Hj (r), j, L) and arrives CA.

The request of ca authentication user Generate Certificate (PK1, D, Hj (r), j, L).Compared with traditional public key certificate, certificate CERTu comprises extra data (Hj (r), j, L).As shown in Figure 6, user can discharge Hj-1 (r) after CA acceptance certificate and initializes the effectiveness of certificate.

If user is because certain reason needs cancellation of doucment, can stop discharging cryptographic Hash and make certificate expired at next renewal point.User, it is even possible that certificate temporarily lost efficacy, the most again discharges corresponding cryptographic Hash and carrys out more new authentication.

The multiple certificate of 3.HIEP describes

In order to solve single point failure and the problem of CA cross-certification, we have proposed a new certificate mechanism being called multiple certificate.We form a virtual tissue (VO) several CA.During one CA certificate, the content signature to certificate according to a predetermined sequence of other members in this virtual organization, and each produce an auxiliary certificate comprising original certificate content and CA self signature.Such as, as shown above, user sends its certificate request road CA.If this request of ca authentication, a certificate will be issued.Meanwhile, auxiliary CA1 also will produce auxiliary certificate 1 to this certificate signature, and then auxiliary CA2 produces auxiliary certificate 2 to auxiliary certificate 1 signature, the like.Therefore it may only be necessary to obtain any one auxiliary certificate just can verify the effectiveness of a certificate, without direct with issue this certificate CA and directly communicate.

4.CRLs shared model

EPC application has user and the resource of enormous amount.Each user and resource hold a certificate.When their certificate needs to cancel, huge CRLs can be brought to CA.The server of CA will become the bottleneck of whole system, and network delay increases, and user cannot obtain certificate revocation information in time.Further, since EPC node is dynamic, it is necessary to ensure that even if all of node also can reliably obtain up-to-date CRLs in the case of listserv is temporarily unavailable.According to this characteristic of EPC, this project proposes CRLs shared model.

Each EPC node downloads CRLs from the LIST SERVER of CA, then issues with the form of EPC service.EPC node is according to according to the rule searching of CA after first other nodes and acquisition CRLs.CRLs is signed by CA with the private key of oneself, to guarantee that CRLs is not tampered with.

5. conclusion

For the first vehicle condition, it is possible to use the New Certificate of one-way hash chain realizes.

For second and the third vehicle condition, it is possible to use the multiple certificate of HIEP realizes.

Whole scheme, is to be realized by CRLs shared model.

Advantage based on the program:

5.1 certificate revocations are the most real-time

Because certificate is issued based on one-way hash chain, user can make certificate temporarily or permanently lose efficacy by the method stopping release cryptographic Hash.This will come more preferable autonomy and safety to user's use certificate book band.Also mitigate CA burden in communication and process simultaneously, the real-time cancelled can be improved.Add and have employed CRL shared model, EPC can be better adapted to and calculate distribution, dynamic feature, it is ensured that all nodes can obtain up-to-date revocation information in time.

5.2 certificate managements are simple and reliable

Owing to have employed HIEP multiple certificate authority mechanism, the certificate that different CA issue can be mutually authenticated, and user's direct the issuing CA and just can verify the effectiveness of this certificate of access certificate, it is to avoid the single point failure of EPC system.

(4) EPC bank preposition system BFS

The realization of 1 distributed BFS parallel calculating method based on Scilab.

Based on Schab [3] computation engine, with OpenBFS/webBFS as background, relate to (the Netbutterfly htbBFS Computing System of Distributed Parallel Computing instrument under BFS environment NBFS) to support that what BFS carried out extensive scientific algorithm realizes platform.

The distributed parallel computing structure of 1.1NBFS

As shown in Figure 7:

A virtual parallel machine is formed by the BFS computer node of multiple offer BFS service.It can complete the parallel computation task submitted to by BFS client.Each BFS calculates node i.e. parallel computation a node, it is provided that one or some can service with the parallel BFS of the tasks such as executed in parallel.As the complete package to calculation resources, BFS calculates node and has been used for concrete calculating task, and he uses Scilab as algorithm description language.User can be reduced and describe the difficulty of scientific algorithm problem.Calculating the abstract computing capability of service layer's (virtual parallel machine), when calculating task is accepted, it will suitably calculate resource and complete by Automatic-searching.Application layer is primarily used to effectively use calculating service and manage, and processes the problems such as many application coordination.Pay space by WEBHTB(Hart) the parallel OPENHTB(Hart that calls pays space) Service Instance.

1.2NBFS designs framework

1.2.1NBFS application structure mode

As shown in Figure 8:

Data capsule mainly leaves concurrent program and application data in.Computing container includes N number of resource node, computing capability is provided for system, Resource TOC service includes calculation resources service and data resource service, when NBFS runs, node sends to data capsule editting of task, data capsule and computing container find resource requirement by directory service, until computing completes.

1.2.2 server system design

NBFS have employed Core server group structure at the unable row that realizes.Client is resource provider and resource transfer person, and intrasystem calculating resource comes from effective gathering of client resource.The server of NBFS uses the clustering design of extension, and modules can be separately operable.Server group structure is as shown in Figure 9.

1.2.3 client node design

The task that includes the client node of NBFS accesses interface and ScilabBFS calculates virtual machine.It is the interface that user applies for entering NBFS that task accesses interface, and user accesses interface by task and task is submitted to NHCS system, and ScilabBFS calculates the operation node that virtual machine is NBFS, and it provides operational capability for system.Client node divides mission mode and computation schema.The former to system submission calculating task and waits for process for node, and the latter provides, to system, the service of calculating for node.So, it supports any machine from microcomputer to giant computer, from Windows to Unix and Linus and any operating system of being likely to occur in the future, greatly facilitate the network parallel between Heterogeneous Computers, such that it is able to sufficiently utilize existing Internet resources to carry out distributed parallel computing.

1.2.4 system coding design

Native system have employed Scilab language and describes language as scientific algorithm script.Scilab is set up automation research institute (INRIA) by France and EBFS develops " open source code " software, use Scilab quickly to grasp with user as quick description of application scenarios language beneficially calculating task, thus improve the user description efficiency to scientific algorithm problem.Owing to the application program of NBFS have employed the mode being construed to perform so that the application scenarios of NBFS directly can run at the NBFS node of different platform, is operated together a concurrent program in different operating system node, has good isomery extended attribute.

In order to make Scilab be applicable to the parallel computation of networking, system adds teledata read write command NBFS-RD and NBFS-WS, eliminating disk operating etc. and may endanger the dangerous command of client computer, the entrance of whole computing program is Mainnhcs file, and other programs are called as process.Mainnhcs is a file describing task flow.Grammatically only have both keyword NBFS-CX and NBFS-END.

The condition of NBFS-CX: program performs, and when expression formula X is true time, system in parallel performs all functions in NBFS-CX statement.

NBFS-END computing terminates, and this instruction is generally used to ends with system task, when system goes to this statement discharges institute's Resources allocation, and application completes.When expression formula X is true time, and whole processor active task terminates.To task, submitter sends end mark.

1.3. key technology

1.3.1 tasks in parallel

NBFS Parallel Scheduling language, task nexus is described, problem is decomposed by people the tasks at different levels in the most corresponding program, multiple programming is natural, clear, simultaneously, tasks in parallel combines the advantage of data parallel and function parallelization, on the premise of supporting relatively high degree of parallelism, it is possible to effectively process irregular problem.More conveniently serial program can be rewritten as concurrent program.System is packaged into different tasks to realize parallelization data and operation.When multiple tasks have same operation, and different pieces of information realizes data parallel, realize function parallelization when multiple tasks have different operating.Each task is divided less than a BFS node, distributed parallel computing based on Scilab can extend and property computing environment pays space to OPENHTB(exploitation formula HTB Hart) network node is in the Wide Area Network of parallel computational nodes, so, can the task of parallel computation can be distributed on BFS in multiple calculating resources, systematic function will be greatly improved.

1.3.2 system communication

System communication relates to two aspects: one is the communication between parallel computational nodes, and the data communication between the BFS service that each BFS mainly completing parallel computation calculates on node exchanges with synchronizing information, and another is that BFS serves communication between client.Can be used to realize communication and BFS between BFS service service and the communicating of client.Communication equipment is shaped with two kinds of implementation methods: PUII method and PUSH method.Wherein push method allows data to transmit together with notice, and this communication mode efficiency is high, for feature performance benefit demand this for parallel computation, can adopt in this way.Additionally, due to BFS service is that therefore, communication efficiency is higher based on TCP/IP this bottom communication mode.

In order to realize NBFS communication under internet, NBFS have employed SOAPV1.2 standard and is packaged it.SOAPV1.2 is loose at one, uses the switching fabric of XML equity and typed information to provide a simple and mechanism for lightweight in the environment of distribution.SOAP itself is not to define any applicational language, he simply defines a kind of simple mechanism, makes it can be by the most eurypalynous system for from message system to RPC (Remote Procedure Call) by this ability of a modular packaging Extension.

NBFS extends Scilab and is encapsulated SOAP, adds the data manipulation instruction of SOAP-EH, NHCS-SOAPEH in Scilab so that user can access the data message in each data buffer storage of system, it is achieved the distributed memory transparency to user.NHCS-SOAP command N HCS-SOAEH.

There are two parameters: [TYPE] determines the operation model that system performs: digital independent or data write: [Name] is for needing name variable to be processed, by the string representation taken the lead with letter, be expressed as when above adding " # " data pointer operation, before without " # " time represent Value Operations.

1.3.3 fault tolerant mechanism

Perfect condition lower network has the feature that shorter communication delay, higher communication bandwidth, extremely low under error rate, preferable autgmentability.And reality is the time delay being difficult to tolerate, limited bandwidth, the most possible makes mistakes, and hence setting up distributed parallel computing knee based on the Internet pain must have a set of fault tolerant mechanism corresponding with unit to adapt to.This computing environment is to be formed by connecting by some the computer Internet being distributed.The fault of one unit or resource does not affect the normal function of other resources in theory, can realize the fault-tolerant of BFS by the inspection of the overall situation.But it is big to realize difficulty.Feasible method is to realize fault-tolerant function by application program itself, in the case of can breaking down again, use insecure tracer cannot solve NB-AC problem, so to weakening his non-trivial condition, obtain NB-WAC problem, then with HB by his reduction to consistent desirable problem, then solve consistent desirable problem with HB, thus complete NB-WAC problem is solved.HB is used to solve, it is possible to solve NB-WAC problem in the Asynchronous message transfer system comprise process failure and link failure, and other the traditional tracers having now known can only solve only to comprise the NB-WAC problem of process failure.The method is applicable to every pair of different correct process and all passes through a BFS passage connection, thus realizes the fault-tolerant purpose of BFS.

1.3.4 safety problem

Owing to using SOAP to carry out bottom communication, the scope that NBFS application can be disposed greatly expands, but can hardly be avoided in exposed node address in running, and node security problem and problem of data safety become the subject matter that system for restricting is disposed.The strategy that can use at present is the most transferable limited trust principle, and the trust of master control system is distributed in units of task by node, and mission script can not access the file system of node, and the internal memory that can only specify system is written and read.

2. the MVC pattern implementation of the support multiple terminals of remaining XML model

Current most typical a kind of MVC pattern implementation, is the J2EE technology that make use of SUN company.J2EE technology mainly includes Servlet.JSP.Java The parts such as Bean.EJB, Filter.In MVC pattern realizes, general JSP respective view, the interface that system is provided by JSP is come mutual with user.JavaBean or EJB correspondence model, processes service logic, and controller realizes due to Servlet, as the hinge between model and view.But, this implementation has a following weak point:

Owing to JSP embeds Java language in the page, causing the mixing of view and controller, destroy the style of MCG design pattern, the defect of this mode makes exploitation and maintenance become highly difficult.

This implementation can support multiple client browser type, but will an expression layer interface for each specific client type.The most identical service logic, for one side browser, needs a set of JSP to form the expression layer view of html format.And for using Hart to pay the mobile phone in space, then need other set JSP to generate the expression layer view of HIEP form.Code redundancy, is difficult to diffusion.

JavaBean or EJB is typically all relevant to specific data base, if changing or adding data resource type or need multiple isomeric data resources integration, then may need again to rewrite code, reusability and autgmentability poor.

For this, in view of BFS faced by be one the most scattered, allos, the data environment of isomery and different terminal uses, in order to be competent between different application systems or realize data sharing between different pieces of information source with mutual, i.e. client and server end bi-directional data exchange.Use a kind of implementation based on XML model, XML virtual data base is i.e. used to replace JavaBean/EJB as the model realization of MVC pattern, simultaneously, by TIM terminal identification module J2MEMIDP(mobile middleware platform) identification terminal type, and unify dynamically to generate the final view of applicable terminal demonstration by XSLT style sheet conversion processor.

System architecture as shown in Figure 10, gives the MVC pattern implementation of XML model.

2.1 designs and realization

2.1.1 controller part designs

Controller is still completed by Servlet, and it is as follows that it realizes process:

Obtain the request (client can be desktop browsers, collection or PDA product etc.) from client

TIM terminal identification module J2ME(cell phone platform) judge terminal type by capture HTTP request head.In HTTP request, table between UserAgent HTB(MIDP mobile information apparatus) Accept(user terminal acceptable MIME file type) the two message header is relevant with terminal type.By safeguarding that the dictionary of a User-Agent and acceptable mime type has carried out the identification of paired terminal.

Access model data XML virtual data base.

Result data by terminal type recognition result and to the access of XML virtual data base is put in context object or request session, accesses for View component.Control is handed to view and is processed.

2.1.2 modelling

It is an XML virtual data base design and realization shown in Figure 11.

Realized XML virtual data base by XML virtual data base and serve as data/address bus, completing with real data resource (can be various traditional relational, pure XML document or other resource types) mutual, mask the difference of each data source, it is provided that consistent Data View.If XML virtual data base provides necessary data converting function or instrument, carry out the mutual conversion of each resource and XML format data, and maintain the mapping relations between XML data and each heterogeneous data source.

XML virtual data base is from controlling to accept XML format request, and generates XML format accordingly, for View component.Its core is: virtual data base engine and data integration configuration documentation.

Data integration configuration documentation

Data integration configuration documentation is a self-defining XML format configuration file, and it occupies very important position in virtual data, it defines request, the grammatical structure of response document, and dynamic queries is decomposed, and merges rule and the associative operation to data base.The essential element of this configuration documentation is as shown in table 1 below with property value:

In table,</htbdate element and/HTBQUERY>Element is similar.

Virtual data base engine resolves data integration configuration documentation, and verifies request according to the configuration information after resolving, and decomposes, performs, merges, and ultimately forms the XML document of format specification.The difference shielding each heterogeneous data source the most here completes.

2.2 view

View be the appearance of model in performance, by xslt processor, and combine XSLT(Extensible Stylesheet Language, extensible style language) pattern unifies dynamically to generate the view of applicable terminal demonstration.

XSL style sheet is used for defining a series of transformational rule, describes how to show XML document.Xslt processor provides a kind of general method, source XML document can be converted into the output format that various client terminal can identify, including the form of HTML-HIEP.The output format of xslt processor is to be determined by the transformational rule of XSL style definitions.Different client types, corresponding XSL style sheet is different.

The process generating the view that can finally be provided to user is as follows:

XML business datum and user terminal browser type is obtained from context or session.

According to the XSL style sheet that browser terminal type selecting is suitable, and after xslt processor carries out format conversion processing to XML business datum, form the format view of final HTML-HIEP.

View is submitted to client device.

2.3 these structural advantages

Model uses XML virtual data base, if needing to add resource type, then only need to increase the mapping of XML virtual data base and this kind of data resource and change, it is achieved that data resource is i.e. broadcast and i.e. used.

It is embedded in Java code with JSP in the most typical MVC pattern implementation, thus causes controller different from view mixing.This structure kind, the XML CSS in view is only used for defining display format, it is achieved user-interface design, it is achieved thereby that model, controller, being completely separated of view.So developer can clear Partition of role, each several part obtains importance amount of money maintainability and is greatly improved.

It addition, this framework uses unified mode to have xslt processor to carry out conversion process, generate the final view being suitable for terminal demonstration.So system representation layer interface just can support multiple client terminal.When needing to add new client type, it is not necessary to change and represent layer interface, only need to increase corresponding XSL style sheet, code very simple and clear, and more preferable modularity and retractility can be obtained.Open the demonstration at EPC services interface as shown in figure 12.
