Embodiment
Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.
The construction method that utilizes the banking terminal of fixed telephone network communication of the present invention, described terminal comprises the banking business of payment function with realization by fixed telephone network and banking system devices communicating, comprise: the terminal casing that the telephone set profile is set, the outside line socket of telephone wire is set on this terminal casing, display screen is set, keyboard is set, the groove of swiping the card of magnetic card/magnetic stripe is set, the receiver that is connected with this terminal shell is set, described display screen links to each other with the terminal casing by rotating shaft, in this terminal casing, circuit board is set, circuit has microprocessor on it, the keyboard treatment circuit, magnetic card/magnetic stripe treatment circuit and data-carrier store, also comprise: the card slot of IC-card is set on described terminal casing, on described circuit board, also has the IC-card treatment circuit in the circuit; The keyboard that can import encrypted message is set on described receiver; In described terminal casing inside SAM card deck is set, inserting SAM card security module thereon can be to carrying out encryption by the account information of the input of swiping the card and the encrypted message of keyboard input.
Adopt the inventive method to make up the banking terminal that forms, the function that possesses POS equipment on the one hand, comprise: the QWERTY keyboard input, the giant-screen of 10 Chinese characters of 5 row *, the LCD of high brightness backlights show, the magnetic card of support standard 2/3 rail Card Reader is swiped the card, and supports the IC-card read-write of standard C OU card, compatible to logic encryption card and adopts the PSAM encrypting module.On the other hand, possess the function of short message telephone machine again, support multi-media voice to play, support the interactive operation guiding of hommization, support dynamic menu, the online upgrading of software in the support terminal, the function expansion is convenient: can refute and connect bar-code reader, radio-frequency card reader.
Fig. 1 shows the network topology structure figure of three kinds of bank's application systems that adopt terminal of the present invention, and total system comprises: terminal, SAM managing card safety subsystem, access subsystem, professional front-end system and management system.In Figure 1A, insert and depend on the fixed network SMS platform that telecom operators provide, front end in the banking system and background devices all will meet the access standard of telecom operators; In Figure 1B, the fixed network SMS platform that does not need telecom operators to provide is provided, business datum only transmits at bank's internal network; In Fig. 1 C, bank disposes the CTSI server voluntarily, terminal uses the fixed network short message protocol to dial in to cti server by PSTN (public telephone network), cti server finish the transaction packet format conversion after carry out communication with professional front subsystem, with on the transaction data that send be converted into discernible instruction, by ICP/IP protocol and banking host communication, carry out relevant operation flow again.This kind structure combines the advantage of above-mentioned two kinds of structures, does not promptly need the support of the fixed network SMS platform of telecom operators, and business datum also only transmits at bank's internal network.
About explanation: the CTSI agreement is that CPE (client's housed device) and server carry out two-way data communication standard is provided on the simulated voice line of PSTN.It has utilized dtmf signaling technology, FSK modulation technique, simultaneously, has used the caller display technique, and has expanded information content displayed, display packing and control device.
The CTSI server mainly is to finish the access of information terminal calling and make a call the access of implementation platform and call out function, i.e. access: comprise signaling and function of exchange and FSK media services function to information terminal.Simultaneously book server provides the information terminal platform needed private resource, comprising: DTMF transceiver, FSK transceiver, voice resource as CAS sound etc., FSK resource etc., and provide management to these resources.
An implementation of CTSI server is based on digital E1 integrated circuit board design, supports industry main flow integrated circuit board.The single deck tape-recorder capacity is 30 line concurrent transactions, has adopted the parallel processing of many cards, and the multichannel multithreading is waited for, real transaction request during concurrent processing, the load balancing of realization total system.Adopt method of synchronization operation at the integrated circuit board aspect, guarantee the quick response of transaction.System can improve whole percent of call completed and performance by the mode that increases E1 card quantity simply during this design.
The CTSI server operates on Windows 2000 platforms, and physical configuration is: common PC server or minicomputer+E1 integrated circuit board+E1 circuit.
Security consideration:
The function of the function of fixed net short message phone and POS terminal is combined, because this terminal is mounted in open place mostly, the pstn telephone net of use also is public communication network.Terminal is finished comprise the banking of functions such as bank card payment, it is the key of total system that the safety of terminal just becomes.The present invention has ensured the safety that bank card is paid from the following aspects.
Cipher key carrier: on terminal, use the carrier of SAM card as key.This SAM card meets the People's Bank " PBOC " standard, and is applied on the existing financial POS equipment, and it can compatible banking system have the IC-card key code system now, and the secret key safety that is kept in bank's encryption equipment can be imported wherein.
The two-stage key code system: adopt the symmetric key encryption system between the terminal of payment system and the payment platform, the master key off line is downloaded, and is kept in the SAM card, not readable can not the detection, working key dynamically disperses to generate by SAM card random number, and one-time pad guarantees security intensity.
Cryptographic algorithm: the built-in multiple hardwares cryptographic algorithm of this terminal: DES algorithm, 3DES algorithm, SAM card are supported algorithm etc., and are met bank's algorithms most in use such as ISO9564 standard, IBM3624 standard, ANSI X9.8, ANSI X9.9, ECB standard.Both the PIN keyboard be can make, data encrypting and decrypting, MAC computing etc. also can be done.
Security about transaction data: each packet all carries out two-way MAC authentication, follows X.99 standard of ANSI.And guarantee that the MACKey that participates in computing dynamically updates, and has stopped the illegal operation of exhaustive detection.Adopt two-way MAC verification, can ensure the integrality of data, avoid data in transmission course, illegally to be distorted or forge financial transaction.
For the sensitive data in the bank card, as card number, password, magnetic track information etc., can adopt to encrypt and transmit, encrypt used PINKey and also dynamically update.Even message is is illegally intercepted and captured like this, the other side also can't find rule from ciphertext, and the password, card number etc. that restore the holder expressly crack PINKey.
