3rd, Internet is responsible for the realization of the bottom communication between user terminal and gateway, gateway and watch-dog.Various buses Define according to unified interface format between the transceiver module of type and core layer, define between various watch-dogs and gateway Unified communication interface format.
2nd, the Model Abstraction of watch-dog and monitored object: decompose and mapping techniques
1st, the modeling of watch-dog
(1) watch-dog as middle in Fig. 3 is partly shown, and in intelligent domestic system, the external interface of watch-dog can simplify It is described as: a 1. watch-dog EBI, realize connecting by bus between watch-dog and intelligent domestic gateway and communicating, always Line type can be all kinds such as can, rs485, rf315/433, zigbee, wifi one kind therein, and each watch-dog is at it Unique bus address is all assigned on bus, therefore, for a mounted intelligent domestic system, data group <bus type Type, bus address > establish one-to-one mapping relations and watch-dog between;2. one or more ports, each port One monitored object unit is connected, and realizes the input detection to monitored object or output control, and port can be passed through in each port Item unique mark.Therefore, for a mounted intelligent domestic system, descriptor <bus type, bus address, port Number > also propose one-to-one mapping relations and monitored object unit between.Here port, can be port physically, The input of certain actual io mouth or output on such as watch-dog are it is also possible to port in logic, such as certain actual physics end Each logic port that mouth is derived from by modes such as addressing.The whole infrared output of a such as infrared transceiver, according to The logic groups of coding, definable goes out multiple logic ports, each logic port different household electrical appliance of remote control respectively;
(2) feature according to domestic electric appliance, the type of watch-dog generallys include: 1. intelligent infrared transponder, is used for Realize the infrared remote control to electrical equipment such as TV, air-conditionings;2. intelligent light regulator, the brightness regulation as light;3. smart jack/open Close, for the turning on and off of power supply of control apparatus equipment;4. intelligent driver, for exporting some logic low and high levels, Relay equipment such as curtain controlling come the direct io of some needs to control outside etc.;5. intelligence sensor, for inputting The digital switch quantity of home appliance or detection simulation input amount, such as photoimpact, touch switch, door sensor, gas sense, cigarette sense defeated Enter;6. intelligent security guard, for coordinating the sideband transmission of the first-class control data of video camera;7. some other specific type Watch-dog etc..
2nd, the modeling of monitored object
As shown in the right half of Fig. 3, for the various monitored object in household, (easily connect from the convenience of electrical control Enter certain standardized port of watch-dog) and user operation natural custom angle, carry out model decomposition and standardization Abstract, target monitoring object is decomposed the monitored object list being abstracted into one or more conveniently accessible standardization watch-dog ports Unit (referred to as " monitored object unit ").For example, for electric equipments such as television set, Set Top Box, air-conditionings, the most intuitively control and decompose " power switch " and " remote control " two monitored object units, and it is respectively connected to a port and the intelligence of certain smart jack/switch Certain port of infrared transponder, system only need to manipulate this two monitored object units by watch-dog this two ports corresponding, Can achieve the manipulation to this television set, as shown in Fig. 4 citing;For the Smoke Sensor of charged pool, only one of which " cigarette sense The monitored object unit of the input detection of input ";For gas valve, then there is the monitored object of the output control of " relay control " Unit;And for monitoring camera, including the monitored object unit of " control passage ", to realize transmitting order to lower levels or extraction state, with And the monitored object unit of " data channel ", for by the video flowing of sideband transmission big data quantity or image stream, this two Monitored object unit, use be probably certain several monitoring device certain several logic port.
3rd, watch-dog/watch-dog port, monitored object/attribute of monitored object unit and its database description of mapping relations And relational calculus
Analyzed according to above, we by two simple and clear databases describe the attribute of these models and they Between subordinate and mapping relations.These database files are saved on intelligent domestic gateway, and user terminal can pass through ether Net acquisition real-time update:
(1) watch-dog database file, contains to all watch-dogs used in current intelligent domestic system Description, the corresponding data storehouse record of each watch-dog.As shown in figure 5, each data-base recording comprises: identification name (is used for Identify a name expressed the meaning of this watch-dog, such as " supply socket 1 in hall ", " infrared transponder in hall " etc.), (such as rf433mhz bus represents that this watch-dog is entered by rf433mhz bus and gateway to bus type belonging to this watch-dog Row communication), bus address (distribute to the bus address of this watch-dog, the other equipment for being different from same bus is entered Row addressing), watch-dog type (identifies the device type belonging to this watch-dog, bus address can be coordinated to realize further addressing Filter or operate the expanded functions, such as " smart jack/switch ", " wireless infrared repeater " etc. such as filtration) and some other The data-base recording item of achievable miscellaneous function
(2) monitored object and monitored object metadatabase file, contain and are made in current intelligent domestic system All monitored object and its description of monitored object unit.As shown in fig. 6, database is arranged in the form of two grades of tree directories Cloth, one monitored object of trunk node on behalf, follow multiple leaf nodes below each trunk node, each leaf nodes comprises One data storehouse record, each record to should monitored object a monitored object unit.Each trunk node has one uniquely Mark, the mark of corresponding monitored object, such as " television set in hall ".Corresponding to the monitored object unit of every leaf representative Data-base recording comprises: identification name (for representing a name expressed the meaning of this monitored object unit, such as " remote control ", " insert by power supply Seat " etc.), this monitored object unit identification name (such as " infrared transponder in hall ", " electricity in hall of watch-dog that are accessed Supply socket 1 " etc.), the port numbers (as " port 1 ") of watch-dog that accessed of this monitored object unit and some other can achieve The data-base recording item (such as operating user right of this port etc.) of miscellaneous function
(3) relationship map parses with searching:
By the relational calculus to " watch-dog database file " and " monitored object and monitored object metadatabase file ", Gateway can easily user terminal in future operation description, be converted into bus message and issue watch-dog, or will from supervise The bus message of control device, is converted into the operation that user terminal can be understanding or state description;
For descending operation, specific way is described as follows: 1. user terminal passes through Ethernet to intelligent domestic gateway Send an operation description (such as: " connecting the supply socket of the TV in hall "), this describes most basic core and comprises one Individual monitored object unit (such as " supply socket of the TV in hall ") and one be directed to the command code of this monitored object unit with Operating parameter (such as " on " power supply).2. after intelligent domestic gateway receives this operation description, from " monitored object and monitoring Object metadata library file " Rigen finds corresponding record according to monitored object mark and monitored object unit mark, obtains this record In " accessed watch-dog mark " (such as " smart jack 1 in hall "), " institute's access watch-dog port numbers " (such as " m ") and other miscellaneous functions parameter (such as " operating right " is " domestic consumer ") etc..3. then, according to obtaining " the watch-dog mark being accessed ", searches, from " watch-dog database file ", " bus type " obtaining corresponding to this watch-dog (such as " can "), " bus address " (such as address is " 2 ") and " watch-dog type " (such as " smart jack switch ").④ Then, according to simple relational calculus, the operation of user terminal in future describes (that is: monitored object unit+behaviour to intelligent domestic gateway Make code and operating parameter) core body portion (that is: the bus of a data message being suitable for sending is converted on bus Type+bus address+watch-dog type+message data, wherein message data=watch-dog port numbers+command code and operation ginseng Number), and be sent in bus according to the message protocol of regulation.5. " bus type+bus address+watch-dog type " is realized to mesh The addressing of mark watch-dog, and " watch-dog port numbers+command code and operating parameter " is responsible for parsing and is converted by watch-dog, in this prison The target port of control device, the operation such as execution output control or input detection.And this port due to this watch-dog, and target prison Control object meta is connected, and then, finally achieves the monitoring to this monitored object unit;
For up operation, specific way is equivalent to a descending above inverse process, is briefly described below: 1. supervise The watch-dog port that is connected through of control object meta sends data to watch-dog, the core body of this data include mode of operation code and Mode of operation parameter.Watch-dog upon receipt of the data, and this port numbers and bus address combination after, by this monitoring The bus that device is located, is sent to intelligent domestic gateway with the form of bus message.2. intelligent gateway receives in certain EBI To after this bus message, according to " bus type+bus address+watch-dog type " therein, from " watch-dog database file " Find corresponding watch-dog mark, then from " monitored object and monitored object metadatabase file " Rigen according to " watch-dog mark Know and port numbers, obtain monitored object unit mark.3. intelligent domestic gateway will " monitored object unit's mark+mode of operation code and behaviour Make state parameter " user terminal is sent to by Ethernet.
4th, the increase and decrease of watch-dog and monitored object or modification
(1) increase and decrease of watch-dog and monitored object and modification, is equivalent to generation and the modification of above-mentioned two database file
(2) readability of user operation for convenience, those some component identifications relevant with user terminal application layer, bag Include watch-dog, the mark of monitored object, the mark of monitored object unit, the (such as " intelligence in hall all by the way of directly expressing the meaning Socket 1 ", " TV in hall ", " power switch " etc.);And those are in the element of core layer or Internet, then can use The form simplification enumerating assignment is processed, and such as bus type can is defined as " 0 ", and bus type rf433 is defined as " 1 ", other prisons The rest may be inferred for control device bus type
(3) especially, the definition of the mode of operation code for various monitored object unit and parameter and parsing, give application layer Complete.In the application layer of user terminal, for each monitored object, database file is had to correspond to therewith, this data library text Part realizes the mapping one by one between the command code of digitized command code and parameter and expressing the meaning and parameter, and referred to as " monitoring is right As descriptive data base file of expressing the meaning ".When user terminal software needs to certain monitored object transmitting order to lower levels, by expressing the meaning Command code and parameter are searched and are obtained digitized command code and parameter, are sent to monitored object by gateway and watch-dog;When with Family terminal software receives the mode of operation code being transmitted up through watch-dog and gateway from certain monitored object and parameter When, by the anti-command code checking in expressing the meaning of digitized command code and parameter and parameter, and the use in user terminal software Family interface display.Therefore, when increasing the monitored object of a new type, increase a pin mainly in user terminal software " descriptive data base file of expressing the meaning " to this monitored object, after so processing, when increasing and decreasing or change monitored object, not only accomplishes Independence with core layer and Internet, and ensure user terminal application software core body and the independence of monitored object, Thus substantially increasing the simplicity to intelligent domestic system increase and decrease or modification monitored object
(4) generation of the abstract and database of decomposition of monitored object and modification, installs first, later stage increase and decrease or change It is dynamically completed during monitored object.User can complete this work by a simple small tool it is also possible to transfer to supply Business uses the mode of monitored object according to user, after above three database file after offline generation, downloads to user terminal soft In part bag and in intelligent domestic gateway.
5th, brief summary
After above-mentioned modeling process, including monitored object is decomposed with abstract database mapping and relational calculus, monitor Object can also be easy to combine and obtain higher level monitoring with the various standardized watch-dog of the access of flexible and convenient, meanwhile The combination and realization support to scene control model.
3rd, the recombinant of monitored object unit and the realization of scene and control technology
1st, the concept of the recombinant of monitored object unit and scene
By above-mentioned through the abstract monitored object unit decomposing and setting up mapping relations and watch-dog port between, if pressed According to the basic composition of single monitored object, reconfigure monitoring in application layer, referred to as simple recombinant, it is possible to achieve to single prison The monitoring of control object.If further, by the monitored object unit of multiple monitored object or multiple monitored object, according to certain use Family custom or functional purpose are combined, and are simultaneously introduced execution sequence and the logic judgment condition of sequencing, then be referred to as complexity Recombinant, or referred to as scene.Scene belongs to a kind of combination form of expression of high-level user view, and such as user wishes returning May want to entrance hall when family and can play music, open entrance hall corridor lamp, and open curtain.These by user enter for electrical equipment The intention of row operation is combined description it is simply that a kind of scene.Simple recombinant to the monitoring of single monitored object, is also made To process for a kind of simplest scene.
2nd, the status attribute of scene and its conversion
(1) scene according to its be presently in state, can be broadly divided into static, activation, and execution state, and some Other facilitating Function Extension can self-defining state further:
1. resting state: scene is initially preserved in the form of the static file stream in the file system with system, scene this State is referred to as the resting state of scene
2. activated state: a scene will be allowed to work in systems, first should be by this scene loading system internal memory.If feelings Scape, after being written into internal memory, does not execute at once but enters and monitor that wait state (waits one and is referred to as " the triggering factor " Reason), then this state after this scene is written into is referred to as activated state.This action by this scene loading system internal memory It is referred to as " activation " of scene, it is typically from the activation command of external user it is also possible to be derived from inside another one scene Nesting allocation order to this scene.The scene being in activated state is a kind of " ready supervision " state, and its moment monitors it and touches Whether whether clockwork spring part is met, and have external trigger commands to arrive.When trigger condition is met, or ought receive External trigger commands, scene can enter execution state from activated state
3. execution state: be in the scene of execution state, scene some row sequences of operation defined can be executed.It is being finished Afterwards, resting state or activated state can be automatically returned to according to the exit criteria of the definition of scene
4. head expander: resting state, activated state, execution state are topmost three states of scene.In order to system increase or Extend some functions, outside these states, some transitional or descriptive states, the referred to as extension of scene can be extended State.The head expander of scene mainly plays some complementary effects
(2) condition conversion of scene:
As shown in fig. 7, the conversion schematic diagram between the three of scene kinds of principal states.It is in the scene of resting state, by swashing Life order or trigger command, and enter activation or execution state.It is in the scene of activated state, return by countermanding an order static State;By trigger command or monitor the triggering factor, and enter execution state.It is in the scene of execution state, ordered by revocation Make or after its sequence of operation is finished, according to attribute or the revocation parameter of scene itself, or enter inactive state, or enter State of activation and restart to triggering the factor supervision.Order mentioned here, or the operational order of external user, or Person is the nesting allocation order from another one scene.
3rd, the inscape of scene
Constitute the key element of scene, comprising:
(1) the mark title of scene:
One title expressed the meaning being used for certain scene of unique mark, such as " home mode "
(2) condition that scene is triggered --- the triggering factor, triggering premise, triggering retention time:
The triggering factor, triggering premise, triggering retention time, for specifying the factor being triggered and about of activated state scene Bundle
1. trigger the factor: be in the scene of activated state, can automatically be triggered when certain or certain several factor occurs and enter Enter execution state, this factor is referred to as triggering the factor.Such as, execute the scene of certain warning function, be typically in monitoring at ordinary times Ready activated state;When someone is detected and come in, warning will be play proceeding to execution state and start execution, send note and lead to The operation such as know;Daily 8 points of night all can automatically turn on hall lamp etc. and simulate the operation that someone is in.Here, " someone is detected Come in " and " daily to night 8 points " be respectively two triggering factors respectively.The triggering factor is the concept of " point ", is divided into shape State change and two kinds of clocked flip.If Status Change triggering, electrically showing as the jump of a data signal is detected Become edge, or certain analog quantity passes through certain threshold value;If clocked flip, show as in time current time reach or Crossing sometime point.The triggering factor can have multiple, is the relation of " or logic " between them
2. trigger premise: the triggering precondition that can play a role of the factor, when only putting forward condition before activation and being satisfied, touch Send out factor ability to be accepted and trigger scene and enter execution state.Such as, certain water flowers scene it is desirable to only on every Tuesdays with four upper 9 points of noon and room temperature when 10-30 degree Celsius just execution water action, here at 9 points in the morning can as a triggering factor, " Tuesday, four " and " room temperature is at 10-30 degree Celsius " is exactly two triggering premises, is the pass of " with logic " between this two premises System.Triggering premise is the concept of " interval ", including state premise and two kinds of time premise.If state premise, in electricity Show as on gas the low and high level state of a data signal is detected or an analog quantity falls in certain interval, if when Between premise, show as in time, current time be located at certain time interval.Premise of setting out can have multiple, between them is The relation of " or logic "
3. trigger retention time: in the occasion of some special applications, needs a period of time after scene is activated, that is, So that presence is triggered the factor and meet triggering premise, also do not trigger this scene and enter execution state.Only exceed when scene is activated After this period, scene just can be triggered there is the triggering factor and under conditions of meeting triggering premise.This period, claimed For " triggering retention time "
(3) sequence of operation collection:
1. sequence of operation collection is the core of scene effect.Scene passes through to explain a series of behaviour in the execution sequence of operation Make, complete the sequence of user described by scene and be intended to
2. sequence of operation collection is made up of a plurality of sequence of operation, and every most basic composition includes: operation object, command code with Parameter, the time migration of sequence execution, the number of times repeating and interval, precondition of execution etc..Wherein, " operation object " Type to include monitored object unit (such as " power switch of the television set in hall "), watch-dog (such as " all in hall Watch-dog "), scene (such as " pattern of leaving home ") and other need the target used in kind (such as " note ", " bus ", " user terminal ") etc.;What " command code and parameter " represented is added to action type and the parameter of operation object, such as " open ", RESET, " after triggering and being finished enter activated state ", " SMS notification, content is xxxx ", " data is uploaded by bus Xxxx ", " notifying user terminal, data is xxxx " etc.;How long the time migration of sequence execution, refer to after scene is activated Time just starts to execute this sequence of operation, and the time migration of each sequence of operation is different, it is achieved thereby that the logic of multioperation is suitable Sequence and time delay execution;Certain operation needs of some occasions repeat, and " number of times repeating and interval " is used for supporting to grasp Make this attribute of sequence;The precondition of execution, is the precondition that this sequence can be performed, such as certain sequence of operation is So description " destination object be the curtain in hall, command code be open, time migration be equal to 10 seconds, the precondition of execution be Outdoor brightness is more than 3 grades ", wherein " outdoor brightness is more than 3 grades " are just carried out the precondition of openable windows curtain action, i.e. only family When outer bright enough, just need to execute this sequence of operation and go to open curtain
3. scene not only completes the sequence of operations description to monitored object unit and combinations thereof, and supports except monitoring In the management of some other destination object outside object and maintenance, such as above example, by the sequence of operation " in reset hall All watch-dogs ", " revocation leave home pattern ", " SMS notification, content is xxxx " etc., are not limited to the behaviour to monitored object Make
(4) the scene state after the sequence of operation is finished:
After all of sequence of operation of scene is performed and finishes, scene can turn to two different states from execution state Change, be activated state and resting state respectively.Some scenes, wish that it can thoroughly exit after all of sequence of operation is finished, Such as " scene of going home ", execute in triggering home mode turn on light, play music, ventilation, after the action such as curtain that opens a window, we are not Need this scene to exist again, then can thoroughly release this scene.And other scene is it is intended that work as all The sequence of operation be finished after, continue back at the activated state of " ready supervision " to continue to monitor the triggering factor, when receiving triggering When the factor, sequence of operation rally is executed once again, such as " security protection scene of leaving home ", today 9 hole irrigation complete spend after, later day If son triggering meet require, need to execute this sequence of operation again, then when execute this scene after it is intended that it Return to state of activation to continue to monitor the triggering factor and condition
This functionality, can be realized by " sequence of operation be finished after a state " mark.
4th, scene describe and explain execution
(1) this programme is described to scene by the way of script file (referred to as scene description script).Script file In comprise multiple scene description script projects successively, each scene description script corresponds to a scene, defines some keywords Characterize each inscape of scene
(2) by executing to the loading of scene description script and explanation, the various intentions of user are realized
1. the activation of scene: scanning scene description script file, the correspondence being obtained according to " mark title " coupling of scene Scene item, the inscape of this scene is loaded in the form of a structure example internal memory, by the setting of the state of this scene For " activated state ", and start to monitor the condition that this scene is triggered
2. the triggering of scene: when the condition of being triggered of the scene receiving external trigger commands or activated state is expired Sufficient, then this scene needs to be triggered.If this scene is not yet activated, first swash according to the method for above-mentioned " the 1. activation of scene " It serves somebody right scene, then trigger this scene.After scene is triggered, each in systematic order scan operation sequence sets operates sequence Row, explain according to the definition in " 3, the inscape of scene ", explain execution successively.When all of sequence of operation (comprises it heavy Multiple number of times) be performed and finish after, according to " sequence of operation be finished after scene state " attribute of scene itself, or When sending " trigger command ", entrained " sequence of operation be finished after scene state " parameter, determine that scene next step is Enter resting state or activated state
3. the revocation of scene: be in the scene of activated state or execution state, can be countermanded an order by outside, exit current State, and enter resting state or activated state.
4th, the user terminal that intranet and extranet uniformity accesses realizes skill
As shown in fig. 1, user terminal includes Intranet user terminal and external user terminal;
For Intranet user terminal, a server end daemon thread, each LAN are opened up on intelligent domestic gateway User terminal, as client, directly initiates to connect (connect) to the intelligent domestic gateway in same LAN, then Communicated by socket (socket);
For external user terminal, but cannot directly initiate to connect to the smart home net in Intranet from outer net.For understanding Determine this problem, the invention provides two kinds of solutions, both schemes can exist side by side.
(1) solution based on router intranet and extranet port mapping technology
The description of scheme: there is certain router to possess a kind of port forwarding function being referred to as " virtual server " in itself, Realize specifying the Service-Port of ip address to be mapped in the inside net of outer network data, thus realizing reflecting the user terminal of outer net It is mapped in Intranet.If on such router, by the clothes of certain port mapping of router to intelligent domestic gateway On business device port, when external user terminal access router corresponding outer net ip address and port, just look like the use in Intranet Family terminal equally connects intelligent domestic gateway server end daemon thread
The advantage of this scheme: implement fairly simple
The limitation of this scheme: 1. in household, LAN optimization outer net must be by supporting the port of " virtual server " The router of forwarding capability completing, when router does not support this function, or, when in household, LAN passes through partial wideband Or during the form accessing external network such as cable modem, the method may lose efficacy.So, this method depends on the side of accessing external network Method, does not possess general applicability, comes on the premise of especially in a lot of households, the mode of LAN optimization outer net has determined During newly-increased deployment intelligent domestic system, this method will be extremely limited.2. router ip address online outside is necessary Fixing, or must be fixed come the domain name to guarantee router using DDNS technology, only in this way, outer net client terminal just may be used With correct ip address or domain name link router.Nonetheless, apply for that fixing ip often increases to outer net service provider isp Plus the hire charge of user;And adopt DDNS technology, in addition to meeting increases certain operation cost, often it also is difficult to guarantee domain The real-time update of corresponding relation between the dynamic ip of name and isp distribution, so in actual operation, even if domain name is fixed, also may be used The problem that cannot be successfully connected can occur.3. this method is also unfavorable for being different from Intranet user eventually for external user terminal The unified management at end.
(2) the external user terminal access technology of intelligent domestic gateway " actively connecting outer net "
The description of scheme: realize to overcome the limitation in above-mentioned " (1) router intranet and extranet port mapping technology ", 1. In outer net node (or equivalent Intranet is to outer net mapping node) one " external network server " (as shown in fig. 1) of upper placement, and It is separately operable two server ends in two ports of this external network server.2. intelligent domestic gateway after powering, as visitor The active of family end goes to connect the corresponding server end in one of port, and sets up socket after successful connection, realizes intelligent family Occupy the communication between gateway and external network server.In order to ensure intelligent domestic gateway and external network server moment keep connecting, that is, Make because the outer net address of router there occurs change, also ensure that the connection of intelligent domestic gateway and external network server is also real-time Update, establish a kind of " heartbeat mechanism " between intelligent domestic gateway and external network server it may be assumed that the intelligent domestic gateway cycle Property ground to external network server send heartbeat querying command, after receiving heartbeat querying command, external network server is to smart home Gateway returns a heartbeat and confirms, when being not received by for a long time confirming from the heartbeat of external network server, smart home net Close and think that the connection with external network server had been lost efficacy, and again initiate new connection and set up new socket communication, and External network server is then communicated with up-to-date connection socket and intelligent domestic gateway all the time.3. external user terminal needs to access intelligence When energy home gateway, first initiate to connect to the corresponding server end in another one port of external network server, and connecting Set up socket after success, realize the communication between external user terminal and external network server.4. external network server completes to be derived from The socket digital data of intelligent domestic gateway and the forwarding between the socket digital data of outer network termination exchange
The advantage of this scheme: 1. because LAN node actively accesses outer net what restriction typically no, this Scheme is not limited by the mode of household Intranet accessing external network completely.2. by external network server to the set from intelligent domestic gateway Connect digital data and carry out forwarding between the socket digital data of external user terminal exchanging, facilitate implementation to external user terminal Unified management, also allow for the strict security mechanism of connection setup between external network server and intelligent domestic gateway.3. outer Network server can be one or more, and the introducing of external network server, conveniently realize intelligent domestic system to wisdom cell and The extension of smart city.Such as one is located on center of housing estate server, and one is located on the central server of operator, then may be used Easily to realize unifying the unified maintenance management in the range of maintenance management and operator in cell.
5th, the encryption of system and communication port and security mechanism
One hardware security chip is increased on intelligent domestic gateway, auxiliary realizes some safe encryption functions.The present invention Propose the safe encryption mechanism of three aspects, strengthen the difficulty with software inverse engineering, farthest ensure that communication is logical The security in road.
1st, it is based on user-defined binary file and encrypt issue mechanism
The software binary file beginning in source is easy to be cracked by reverse-engineering.One software two acquiring the source beginning enters The approach of file processed occurs in the issuing process of binary file, issues link including producing, updating (containing downloading upgrading) etc.. The present invention proposes a kind of scheme, allows binary file when being published, and carries out adding using user-defined AES Close, and its corresponding decipherment algorithm is before manufacture, cured in safety chip.Program after the binary file downloading encryption Before in the rom of write intelligent domestic gateway, first it is decrypted by safety chip.Produce and maintenance for the ease of unified, here Enciphering and deciphering algorithm, for all intelligent domestic systems in a batch or an operator field, is all consistent.This Mechanism, contributes to increasing the difficulty of reverse-engineering it is ensured that the profit of operator, protects privacy and the interests of terminal use.
2nd, the code storage of the encryption and decryption based on hardware uniqueness and load mechanism
The software binary file beginning in source is easy to be cracked by reverse-engineering.One software two acquiring the source beginning enters The approach of file processed occurs in the rom of production board preserving binary file.The present invention proposes a kind of scheme, allows and downloads to intelligence The binary code of energy home gateway, before programming enters rom, first passes through safety chip and is encrypted, and in intelligent family After occupying gateways and starting loading code from rom and before execution code, it is decrypted by safety chip.The parameter of this encryption and decryption It is solidificated in advance in safety chip.The encryption parameter that every safety chip is used is all different, therefore each smart home net Close the binary file being saved in rom after encryption all different.So, even if the rom from certain intelligent domestic gateway Read out binary file it is also difficult in other intelligent domestic gateways or the smart home that do not have safety chip after burned Execute on gateway.This mechanism, substantially increases the difficulty of reverse-engineering it is ensured that the profit of operator, protects terminal use Privacy and interests.
3rd, the dynamic encryption and decryption communication mechanism based on hardware uniqueness and asymmetric arithmetic
Guarantee the encryption safe of data communication channel, especially ensure that intelligent domestic gateway and external network server and outer net The encryption safe of communication port between terminal, for the privacy of the security ensureing system operation and protection user, plays pole Big effect.The present invention proposes a kind of dynamic encryption and decryption communication mechanism based on hardware and asymmetric arithmetic, specifically describes such as Under:
1., to (private key and public key), key is to length for the key being implanted into a pair of rivest, shamir, adelman in every safety chip Degree is no less than 1024, referred to as unique key pair.Every safety chip is allocated a unique chip id, and it is implanted into Key is to also all different.2. by the chip id of the safety chip in relevant range and its public key, form a database, protect There is a secure hardware (higher security level is other) or encryption file (relatively low level of security) is inner, be dealt into intelligent domestic gateway communication Other side's (external network server or LAN subscriber terminal).3. intelligent domestic gateway with far-end server set up connect after, or Person after listening to being successfully connected of Intranet user terminal, locally dynamically generating a pair new key pair, will therein dynamically Public key with after the private key encryption of unique key pair, together with oneself chip id sent along to far-end server or LAN subscriber Terminal.4. after far-end server or LAN subscriber terminal are derived from the data of intelligent domestic gateway in receiving 3., according to chip Id search secure hardware or encryption file in database, find this chip id correspond to intrinsic public key, then use this public key to add Dynamic public key decryptions after close out and are saved in local.Then, far-end server or LAN subscriber terminal are also in this earthquake State generates a key pair, and is sent to smart home net with public key therein with searching the intrinsic public key encryption obtaining above Close.5. intelligent domestic gateway is receiving with the far-end server after the intrinsic public key encryption of oneself or LAN subscriber terminal After dynamic public key, decrypted with the intrinsic private key of oneself.So far, intelligent domestic gateway and far-end server or LAN subscriber Terminal, all obtains the dynamic public key of respective other side, simultaneously in store respective dynamic private key.Then, intelligent domestic gateway and Far-end server or LAN subscriber terminal when transmission or receiving data, with respective dynamic key encryption, and use right The public key of side is decrypted.6. in order to further enhance security, the actual effect for dynamic key pair is made stipulations, when certain is dynamic After the time that state key uses exceedes the time of certain regulation, the both sides of communication regenerate respective key pair, and on repeating Face 3.~similar procedure 5., respective dynamic public key is sent to other side
The advantage of this mechanism, in addition to itself advantage having given full play to asymmetric arithmetic, also resides in: 1. due to each The unique key preserving in the safety chip of individual intelligent domestic gateway to different and not to external leakage, so, even if certain The encrypted tunnel of intelligent domestic gateway is broken solution, nor affects on the communication port of other intelligent domestic gateways;2. due to communication During, key that most times are used to for the dynamic temporary key generating in scene, so system itself is intrinsic Key is very low to the probability being exposed and crack;Meanwhile, 3. because dynamic key is ageing to having, so it may be difficult to obtaining Obtain the sufficient amount of ciphertext of same encryption parameter, therefore increased the difficulty cracking;Even if in addition, certain smart home The encrypted communication channel of gateway is broken solution, is also merely only to crack within that time effectively.User can freely adjust The section frequency to dynamic change for the key, and seeking to put down between shared bandwidth and enhanced security because dynamic password exchanges Weighing apparatus.
