101: the basic format of definition encryption equipment return data, defines buffering area by basic format;
This step is specially:
1) first and second bytes are combined into the length n of an integer as encryption equipment return data;
Total data length is: 0xFFFF (16 system)=65535(decimal system) byte 8 bit, i.e. FF, by height displacement, that is: the first byte is most-significant byte, second byte is least-significant byte, realize the length of data, (byte [0] & 0xFF00) >>8, (byte [1] & 0x00FF).
2) third and fourth byte is as return type;
During practical application, each encryption equipment can a corresponding return type, and the encryption equipment return type of different manufacturers is different, and the encryption equipment that the embodiment of the present invention adopts is: based on the Hua Da instruction set of SJL06 cipher machine, when relating to calculating MAC value, the resultative construction that encryption equipment exports is table 1:
Table 1
| Domain output | Length | Type | Content |
| Answer back code | 2 | A | MH |
| Error code | 2 | H | 00 represents correct |
| MAC | 1-8 | B |
Can find out that A is printable character by table 1; B is any character, 0x00-0xFF; H is hexadecimal character ' 0 ’ – ' F ', and the return type of encryption equipment is MH, and the return type of the embodiment of the present invention to encryption equipment does not limit.
3) the 5th and the 6th byte is as returning results;
5th and the 6th result phase that byte returns ' 0 ' ' 0 ' represents encrypts successfully, and other return results such as: ' 0 ' ' 1 ', ' 1 ' ' 0 ' and ' 1 ' ' 1 ' all represents that encryption is unsuccessful.
Namely, in the data that encryption equipment finally returns, front 6 byte representation basic formats, encrypted result length is n-6 byte, when data length and front 6 bytes are all correct, represents and returns enciphered data success.
4) according to the basic format definition buffering area of encryption equipment return data.
This step is specially: design buffering area is byte [X] [Y], and this buffering area can store many simultaneously return results, and every bar returns results as a line, the agreement of the every a line of planning buffer area:
The length of store byte in byte [i] [0] and byte [i] [1];

Store in byte [i] [4] and byte [i] [5] and return results state, ' 0 ' ' 0 ' expression is encrypted successfully;
Storage encryption content in byte [i] [6]--byte [i] [Y].
102: card reader reads initial data from highway electric prepaid card, and by original data transmissions to server;
Being operating as of this step is conventionally known to one of skill in the art, and itself determined by each card reader, the embodiment of the present invention does not limit this.
103: server creates connection pool object factory, assembling thread and reads thread, by connection pool object factory, initial data is verified, and by assembling thread, the initial data after checking is put into the buffering area of encryption equipment with the form of message, the index index in return cache district;
In order to not process after a time out, and ensure that subsequent request returns result accurately again when not closing connection, go to read data for each communication object Socket provides one to read thread, strictly hold data format, and data are write in the buffer with strict form.
1) the connection pool object factory of definition and encryption equipment communication, and create connection pool object factory;
Realize the management to communication object Socket by connection pool object factory, create connection pool object factory and comprise: formation object makeObject(), activate object activateObject, destroy objects destroyObject and identifying object validateObject.
Wherein, formation object makeObject() be when system starts, according to the connection pool degree of depth of definition, program communicates with encryption equipment automatically, generate communication object socket(such as: formation object makeObject() can as the machine of in connection pool object factory, by this machine, just can make communication object socket); Simultaneously in object-oriented language, invention defines a complete connection pool object, the core of this connection pool object is communication object socket, has simultaneously and activates object properties, destroy objects attribute, identifying object attribute etc.
Communication object Socket has two attributes to be respectively: normal operating level line parameter and maximum operation level line parameter, and wherein, normal operating level line parameter acquiescence creates the quantity of communication object Socket in connection pool; The quantity of maximum operation level line parameter extendible communication object to greatest extent Socket, provides for subsequent use for interim request Concurrency amount increases.
Under normal circumstances, communication object socket in connection pool object factory can meet the demands, when temporary needs more communication object socket time, the communication object of (to greatest extent quantity-normal quantity) can be created, after finishing using, by destroy objects destroyObject releasing resource.
2), after the communication object Socket in connection pool object factory is used, this communication object Socket is activated;
Prevent multiple thread from holding a communication object Socket in practical application simultaneously, ensure that other threads cannot use the communication object Socket activated by activation manipulation.
3) after each request gets communication object socket from connection pool object factory, link checking is carried out to communication object socket, if return results correct, then proceed cryptographic operation, otherwise, destroy connection pool object, and obtain new object and again link checking;
Wherein, when each communication object socket of use, in order to ensure communication object socket, in connection pool object factory, still survive is effective, by checking validateObject method, whether communication object socket is survived and verifies, the rule of checking is: carry out heartbeat checking to communication object socket and encryption equipment, send the heartbeat identifying code that link identifying code 16 0(encryption equipments are supported): 0000000000000000, if communication object socket returns results normally, proceed cryptographic operation; Otherwise stop this communication object socket by destroy objects destroyObject, and obtain new communication object socket and again link checking.
4) definitions section wiring journey, composition thread is used for assembling the initial data by checking, is formed and sends message, put in the buffering area of encryption equipment;
Aforesaid operations makes after having calculative request access, does not need this request to communicate with encryption equipment at once, but after the content of request is submitted to, waits thread to be read to notify this request, thus can increase work efficiency.Because after each request of tradition, set up Socket communication, then wait is needed, this wait can only be set to regular length, and in Practical Calculation process, according to the load of the type of service calculated, encryption equipment, these stand-by period are not identical, the time that there is no need to be fixed is waited for, thus consumes the wait resource of encryption equipment.
5) encryption equipment returns the index index of buffering area byte [index] to server, and thread is read in definition, reads thread and is used for from buffering area, reading encrypted data according to index index.
Just can be arrived the assigned indexes of buffering area by this operations server under, reading the data after encryption by reading thread, avoiding the waste of resource.

Preset rules is: 1, the result length of computations, can not be greater than the data length n of definition; 2, the resultant content that encryption equipment returns is a complete array (whether encryption equipment result of calculation is filled correct, does not need to consider).
Wherein, dislocation described above refers to: in calculating in concurrent processing, whether correctly can only verify memory location, affect whole result according to byte [2] ' M ', byte [3] ' H '.
105: server reads encrypted data from buffering area, and transfer to data card, data card receives encrypted data and is sent to highway electric prepaid card, and highway electric prepaid card calculates according to encrypted data.
Such as: the electronics prepaid card that highway uses at present is a kind of CPU card, uses the key management based on decentralized algorithm, namely deposits female key in encryption equipment, when card issuing is initialized, female key uses decentralized algorithm, and according to card number, calculate a sub-key, be put in card.
When needs operate card time, such as: A information is write in card, now, need writing the card time, write card data, card number and card and automatically generate the information such as a random number and be sent in encryption equipment, encryption equipment calculates according to these information, generate a MAC code, turn back in card, card equally also can according to sub-key, above-mentioned content is calculated, also can obtain a MAC code, if these 2 MAC codes are identical, illustrate that legal permission carries out writing operation.
When there being encrypted data in buffer area, reading thread can go to obtain the byte [] specified in buffer area by index index, obtains encrypted data, and returns the character string of encryption after verifying effective length.Wherein, when after reading thread waits time-out, server first can wake the reading thread of external standby time-out up, reads thread and obtains encrypted data again.
This method verifies effective length according to the data length of definition and first six digits, result of calculation is stored in the buffer memory of n-6 by encryption equipment, when the byte [] specified in buffer area is greater than n-6, show that the byte stored in buffer area is illegal, non-effective data result.
When encrypted data is not read in server timeout, when namely there is long-time untreated index, read thread and can destroy this communication object Socket, guarantee that the communication object Socket in connection pool object factory is always in metastable state.
During specific implementation, in order to releasing resource, this method also comprises: when closing whole service, all communication object socket set up is carried out closedown and destroys, releasing resource.
