Embodiment

Robotization is handled in the different medical insurances of medical insurance medical system and the medical station (comprising medical insurance medical treatment master station) between two main frames, and is as follows with communicate by letter accurately (Fig. 1) by the safety of internet:

The information that source machine from medical insurance and medical station sends; Through the excellent machine of source end, arrive the source end " program of scrutiny program " is housed and source ends such as " source end encipherors " is distinguished machine; Through elimination virus with after encrypting; Pass through the internet; Distinguish machine to the Su Duan that " program of scrutiny program " and " place end decrypted program " etc. is housed; After deciphering and checking virus; Forward the excellent machine of place end to; Arrive place end purpose computing machine at last.

In medical insurance and medical station system, the machine of distinguishing of each medical insurance and medical station is equipped with identical " program of scrutiny program ", " source end encipheror " and " place end decrypted program " standard program.Like this, distinguish that machine all can monitor the information of turnover medical insurance and medical station for every, and refusal is illegally to the visit of each medical insurance and medical station.

For the system that has numerous medical insurances and medical station, satisfy the requirement of interactive application and stability; Has interoperability; Can distinguish the different security requirements of a concrete file; The foundation structure that can use public-key authenticates and encryption key distribution.

In medical insurance and medical station system, each distinguishes that machine also can be equipped with identical " to unit authentication encryption and authoring program " standard program, and these distinguish the Access Control List (ACL) that each Hostname (perhaps address) in each IP address table of distinguishing machine and each medical insurance and the medical station is all arranged in the machine in each medical insurance and the medical station.Like this, distinguish that machine all can monitor turnover medical insurance and each medical insurance of medical station system and the information of medical station for every, and refusal is illegally to the visit of internal institution medical insurance and medical station.

" program of scrutiny program " function: the source end is checked information after distinguishing that machine receives cleartext information, finds they to be arranged in together, and to be presented on the display of computing machine after the program wherein.If these programs are legal programs, allow its visit; Then the user selects " allowing later on " final election item when prompting occurring for the first time, distinguishes and can not inquire once more when machine is met these programs later on, and allow its visit.When the user does not answer within a certain period of time or selects " not allowing " final election item, the machine of distinguishing just abandons this program.The source end is distinguished prow elder generation and this program of isolated operation.

The machine of distinguishing is installed " program of scrutiny program " afterwards, just can prevent that virus attack from distinguishing the excellent machine network that organizational security protects.

" source end encipheror " function: the source end is distinguished machine sends desire by common network cleartext information back, adds the secret key of symmetric cryptography; With this data splitting input one-way hash function (Message Digest), draw hash (Hash) value (source end hashed value); Then source end hashed value is added in cleartext information (not comprising key) back, encrypt, become ciphertext with key; At last this ciphertext is sent to Su Duan and distinguishes machine.

" place end decrypted program " function: Su Duan distinguishes the machine decrypt ciphertext of the cipher key shared of as offered with reception, becomes expressly, obtains cleartext information and source end hashed value; Key is added in cleartext information (not comprising hashed value) back; With this data splitting, input is the one-way hash function of agreement in advance, obtains hashed value (place end hashed value); This place end hashed value is compared with the source end hashed value that receives; If these two hashed values are identical; Confirm that then this information distinguishes that from legal source end machine sends, accept this information; The place termination that sends in the excellent machine network of this place end is received on the computing machine, otherwise abandons this information.

The simple approach of authentication (Authentication) is that each distinguishes the database of setting up a username and password in the machine.

The machine of distinguishing passes through Access Control List (ACL), and (Access Control List ACL) carries out authentication.This tabulation is discerned dissimilar source-end networks (is representative to distinguish machine IP address) identity simply.When the relation of only guaranteed user and IP address is determined, just can come into force based on the authentication of address.

Whom authentication controlling can visit proprietary net, authorizes (Authorization) to stipulate then what the user after obtaining this network qualification of visit, can do.

Authentication and mandate new method are to set up a user or unit name, IP address, password and authorization privilege database.

The machine of distinguishing carries out user's (referring to other unit, affiliate unit or remote client) authentication by Access Control List (ACL).This tabulation to dissimilar source ends (user name), distinguish that machine IP address and user's password carries out identification.When having only user name, IP address and user's password identical, could guarantee to come into force based on the authentication of address with this Access Control List (ACL).

" to user's authentication encryption and authoring program " function: user's (referring to other unit, affiliate unit or remote client), encrypts with private key for user at the password that certain unit stays it; Ciphertext is as user's digital signature; With the unit PKI to digital signature and symmetric key encryption, as confidential paper; With cleartext information, user name and client public key symmetric key encryption; The source end distinguishes that machine is with this ciphertext, confidential paper; By the internet, the Su Duan of the unit's of passing to proprietary network distinguishes machine; The Yong Si Keying of unit is decrypted confidential paper; Then with symmetric key with this decrypt ciphertext, obtain cleartext information, user name, client public key and number signature that the user sends; Yong Hu Gong Keying is with the deciphering of number signature; This Su Duan distinguishes that machine contrasts the relevant information in user name, IP address and user cipher and the unit data storehouse.If entirely true, unit confirms that this information is that the user sends; This distinguishes that machine is by visiting its control tabulation; Determine user right; By the excellent machine of place end, be given to the receiving computer of corresponding authority again.

" to unit authentication encryption and authoring program " function: the password encryption that unit stays in this unit user's (referring to other unit, affiliate unit or remote client) with its private key, ciphertext is as the units word signature; User's PKI to units word signature and symmetric key encryption, as confidential paper; With cleartext information, unit name and unit PKI, use symmetric key encryption; The source end distinguishes that machine is with this ciphertext, confidential paper; By the internet, the place end client computer or the other unit Su Duan that pass to the user distinguish machine; The user uses its private key, and confidential paper is decrypted; With symmetric key with this decrypt ciphertext, cleartext information, unit name and unit PKI that the unit of obtaining sends; With the Gong Keying of unit the units word signature is deciphered; Obtain the password that the user stays in unit; Place end subscriber or other unit are distinguished the password contrast of machine with password unit of being reserved in it then.If entirely true, the user confirms that then this information is that unit sends.

Insurance institution is made up of several medical insurance browsers, automatic cash dispenser, excellent machine and database server etc., electronics doctor's ticket and information processing and 3 parts of management software.Wherein data processing and management software are mainly finished data information memory and management, carry out input and output control etc.

1, the medical insurance general headquarters of certain mechanism and its are distributed in each internal network (being the medical insurance station) of several trans-regional medical insurance branch officeses etc. of diverse geographic location, wherein each is respectively by distinguishing that machine and internet (Internet) couple together, and makes up this mechanism's medical insurance wide area network system (Fig. 1) of a safe and reliable and information interoperability.Information between two main frames of the different internal networks of this system is passed through internet (Internet) intercommunication safely and accurately.

Existing virtual private network technology carries out the deception that illegal internal resource is visited for many by camouflage medical insurance address, and is powerless; Also can't avoid the hacker to get around authentication and authentication scheme, the camouflage identity is destroyed existing the connection.

The information flow of medicare system, information transmitted is through encryption, end-to-end and authentication on the internet; Guarantee information confidentiality, integrality and authenticity; Ability with opposing assault network.

The work of browser/server pattern is all adopted in each medical insurance and medical station, characteristics: user side replaces client computer with relatively uniform browser.Because the application program of browser is some the most basic requirements.Exploitation, maintenance and the upgrading of each medical insurance and medical station (LAN (Local Area Network)) are only carried out on excellent machine like this, do not need browser is reinstalled its application program one by one.

Browser is the computing machine of an access and display message; It comprises a plurality of application programs, and determines that according to object name which application program solves this object.It is concentrated into output information the signal fritter of " packet ", and issues excellent machine in order.In order to ensure not having many browsers simultaneously to excellent machine transmission signals; All browsers, client computer and distinguish machine etc., all adopt a kind of multiple access carrier sense/collision detection (Carrier Sense Multipte Access With Collision Detect, distributed coordination scheme CSMA/CD) and binary power repeating transmission (binary exponential backoff) technology of being called.When a browser during to excellent machine transmission signals, other browsers can the detected transmission signal, and wait for this browser input finish after input again.Each " packet " is all very little, and every browser can not experience long wait.This just guarantees that every browser can both carry out business processing rapidly, timely.

The excellent machine in medical insurance station receives the solicited message from the medical insurance browser at any time, this request is handled immediately accordingly, and given browser etc. the response message of result.It is except sending the static Web document to browser; Can also go to handle the data in the interactive list according to the concrete request of medical insurance browser.Excellent machine output information also adopts multiple access carrier sense/collision detection and binary power retransmission technique.It not only has processor and enough storeies fast, can move a plurality of clients and server program simultaneously, and has the operating system that allows a plurality of application programs concurrent (concurrency) to carry out.Excellent machine all should have a server program in operation mutually to various service.That is to say that it can move the different server program simultaneously.In the design of excellent machine, main task (task) is created a new task for each client computer.Server program is made up of two parts: a part is responsible for receiving request and is generated new thread, and another part comprises the code of handling single request.When a concurrent server begins to carry out, has only first in operation.That is to say, server main task operation first, the request of wait reaches.When request arrived, main task was created a new task and is handled it.Handle tasks requested operation second portion code, stop then.Main task keeps server to be in active state simultaneously.

The most useful function of client's (perhaps browser)/server mode is arbitrarily mutual between client computer and the server.Its feature provides the server of certain service, can become the client of another service.A plurality of clients can visit a server; The server of a service also can become the client of another service.(Application ProgramInterface API), is adapted to concurrent program work to application programming interfaces.Excellent machine sends to browser to the result who needs by hypertext browsing information retrieval (HTTP) mode, and browser is write data with electronics doctor ticket placed on it, by the liquid crystal display displays of electronics doctor ticket.

Medical insurance and medical station database server allow a user, inquire about an above data message simultaneously.It also allows a plurality of users, simultaneously data query information.Wherein application program is read in data from magnetic medium (as disk), carries out data processing, outputs to the excellent machine in medical insurance and medical station then.Data come to this from the output file of database server, are transferred in the input file of excellent machine to go.Transmission service use file transfer protocol (FTP) (File Transfer Protocol, FTP).This agreement allows any file of transmission, and allows file to have entitlement and access rights.It is applicable to the isomery system---can be at transfer files between the computing machine arbitrarily.Whether number order wherein allows user's assigning remote computing machine, provide license, inquiry telefile can obtain, and one or more file of request transmission.Internet protocol series (ICP/IP protocol) has comprised a file access (file access) service.File access service allows remote computer only to duplicate or changes the small fragment file and need not duplicate whole file.

(Network File System NFS) allows application program to open a telefile to network file system(NFS), moves to an assigned address hereof, and begins to read and write data in this position.

The excellent machine in medical insurance station can go to carry out some other programs according to the actual needs of the concrete request of browser (perhaps distinguishing machine), for example the form data that the user imported is write database.(common gatewayinterface, CGI) program can be handled the data in the interactive list to CGI (Common Gateway Interface) of its operation; Can inquire about database, add, processing such as modification and deletion record; Can be the result who handles HTML (Hypertext Markup Language) (Hyper Text Markup Language, HTML), one of instant generation dynamically generates web document, and this web document returned to excellent machine, again by HTML (Hypertext Markup Language) (Hyper Text Transport Protocal, HTTP), by the CGI (Common Gateway Interface) program this web document of dynamically generating send to browser (perhaps distinguishing machine).

The medical insurance station distinguishes that machine installs various anti-virus softwares, and internet system is monitored in real time; The virus information database of regular update anti-virus software is so that safeguards system exempts from viral attack to greatest extent.Just in case certain medical insurance LAN (Local Area Network) is suffered the virus attack on the internet, also only distinguish the machine paralysis, can't have influence on the normal operation of this LAN (Local Area Network).

The machine of distinguishing also can all external references of detail record; Prevent the unauthorized access of external information on the internet simultaneously.It makes the visit of extraneous computing machine to the medical insurance LAN (Local Area Network), can only concentrate on the machine of distinguishing earlier.This just guarantees the reliable and safety of other all computing machines on the medical insurance LAN (Local Area Network).The machine of distinguishing also allows coupled excellent machine, by the internet, transmits and receive the enciphered message of other medical insurance LAN (Local Area Network) of native system.

When a medical insurance LAN (Local Area Network) sent information to another medical insurance LAN (Local Area Network), this information content at first machine of distinguishing of the side of being sent out was encrypted, and by behind the router inspection destination address, was sent to distinguishing on the machine of another medical insurance LAN (Local Area Network) by the internet then.When information arrived, take over party's router judged according to the IP address of transmit leg whether information allows to pass through.After take over party's the machine of distinguishing authorization information and the deciphering, information is given to the medical insurance LAN (Local Area Network) handles.Obvious this network new technology allows the mechanism of the medical insurance LAN (Local Area Network) of a plurality of dispersions, and internet usage is set up the proprietary wide area network that belongs to this mechanism as circuit.

The machine of distinguishing at medical insurance station not only contains the program of browser, and (messageauthentication code, MAC) technology is encoded to the transmission data, guarantees to be subjected to the information integrity of malicious attack but also can adopt message authentication codes.Its typical encoding mechanism is cryptographic hash (cryptographic hashing) mechanism.It is equipped with program and some application programs of medical insurance browser.Distinguish the program of check virus on the machine, allow the user capture on the qualified internet; Also allow inner excellent machine directly to visit the outside.It contains the file transfer protocol (FTP) CLIENT PROGRAM, can set up one with specified server between be connected and carry out file transfer.In order to obtain the authorization, the user must provide login name and password.

Each medical insurance LAN (Local Area Network) (medical insurance station) and general headquarters' LAN (Local Area Network) (medical insurance master station) among Fig. 1, with the internet respectively by distinguishing that machine is connected, a proprietary network that is built into jointly can provide remote access, the mutual visit of the safety of medical insurance LAN (Local Area Network) and general headquarters' LAN (Local Area Network) etc.

The excellent machine in medical insurance station has the central processing unit (CPU) the strongest in the LAN (Local Area Network) at its place and the internal memory of powerful capacity.Its major function: port (as the TCP80 port) state that constantly detects this machine; At any time receive from computing machines such as browser or workstations and distinguish the solicited message of machine, each request is handled accordingly, and the response message of result, send in the LAN (Local Area Network) such as medical insurance station browser or workstation computing machine and distinguish machine.It also includes the medical insurance station is managed, and guarantees its safe and reliable supervisor.It is except sending the document to the computing machine in the LAN (Local Area Network) such as medical insurance station browser or the machine of distinguishing, can also or distinguish the needs of the concrete request of machine according to the computing machine in the LAN (Local Area Network) such as medical insurance station browser, do some other thing (as the data of being imported by the medical insurance people, write database or to data inquire about, add, processing such as modification and deletion, and a result who needs sent to browser or distinguishes machine etc.).In its calculator memory reservoir, contain the data in the frequent database that uses of needs.

Medical insurance station database server stores the message file all insurants of various places of this mechanism (for example certain insurance company).It in time closes this library file to after the data library file operation, in order to avoid artificial maloperation or other faults take place, and cause the damage of Current Library file.After the list structure definition of database, can make amendment as required.For example insurant's situation changes etc.

Backup software provides complete data protection.For example Veritas NetBackup software adopts the level Four hierarchical structure, and centralized management adapts to multiple application structure.Its technical characterstic is that flexible setting, disaster recovery, parallel processing, data are reliable, easy to use, monitoring capacity and system data recovery etc.

In medical insurance master station or the important medical insurance station, the miscellaneous service that can handle is placed in online storage (OnStore) equipment at present, guarantees to read at any time the data of these electronics doctor ticket.For taking precautions against contingent data disaster, use offline storage (OffStore) equipment that these professional data are carried out back-up storage.
