Description

A kind of transmission security key sending method and system, operating terminal
Technical field
The present invention relates to E-Payment field, relate in particular to a kind of transmission security key sending method and system, operating terminal.
Background technology
(BANK Card) is more and more universal as the means of payment for bank card, common bank card paying system comprises point of sales terminal (Point Of Sale, POS), POS receives single system (POSP), code keypad (PIN PAD) and hardware encipher machine (Hardware and Security Module, HSM).Wherein POS terminal can be accepted bank card information, has communication function, and the instruction of accepting teller completes financial transaction information and the equipment of exchange for information about; POS receives single system POS terminal is managed concentratedly, comprises parameter downloads, and key is downloaded, and accepts, processes or forward the transaction request of POS terminal, and to POS terminal loopback transaction results information, is the system of centralized management and transaction processing; Code keypad (PIN PAD) is that the relevant key of various financial transactions is carried out to safe storage protection, and the safety equipment that PIN are encrypted to protection; Hardware encipher machine (HSM) is to the peripheral hardware equipment that is encrypted of transmission data, for correctness and the storage key of encryption and decryption, checking message and the document source of PIN.Personal identification code (Personal Identification Number, PIN), personal identification number, is the data message of identifying holder's identity legitimacy in on-line transaction, in cyber-net system, any link does not allow to occur in mode expressly; Terminal master key (Terminal Master Key, TMK), during POS terminal works, the master key that working key is encrypted, encrypting storing is in system database; POS terminal is widely used in bank card and pays occasion, such as manufacturer's shopping, hotel's lodging etc., is a kind of indispensable modernization means of payment, has incorporated the various occasions of people's life.Bank card; debit card particularly; generally all by holder, be provided with PIN; in carrying out payment process; POS terminal is except above sending the data such as magnetic track information of bank card; also want holder to input the checking holder's of PINGong issuing bank identity legitimacy, guarantee bank card safety of payment, protection holder's property safety.In order to prevent that PIN from revealing or being cracked; requirement is from terminal to issuing bank in whole information interactive process; whole process is carried out safety encipher protection to PIN; do not allow any link in computer network system; PIN occurs in mode expressly, so the POS terminal of the PIN of acceptance input at present all requires to be equipped with key management system.
The key code system of POS terminal is divided into secondary: terminal master key (TMK) and working key (WK).Wherein TMK, in WK renewal process, is encrypted protection to WK.Between every POS terminal and POS, share unique TMK, must have safeguard protection, assurance can only write device and is participated in calculating, and can not read; TMK is a very crucial root key, if TMK is intercepted, working key is just cracked than being easier to, by serious threat bank card safety of payment.So can secure download TMK to POS terminal, become the key of whole POS terminal security.Conclude existing TMK download scenarios below as follows:
1, the female POS scheme of key: user receives single system hardware encipher machine and the same traffic encryption key of the female POS input of key at POS.POS terminal is received single system initiating terminal master key download request by the female POS of key to POS, POS receives single system and drives hardware encipher machine to generate at random terminal master key, and by traffic encryption key encrypted transmission to the female POS of key, the female POS of key is with being transferred to POS terminal after traffic encryption key deciphering again, POS terminal obtains terminal master key expressly, be saved in POS terminal password keyboard, thereby realize POS terminal and POS, receive the synchronous of terminal master key between single system.
2, IC-card decrypt scheme: user receives single system hardware encipher machine and injects the same traffic encryption key in IC-card at POS.User inserts POS terminal by IC-card, POS terminal is received single system initiating terminal master key download request to POS, POS receives single system and drives hardware encipher machine to generate at random terminal master key, and by traffic encryption key encrypted transmission to POS terminal, traffic encryption key deciphering terminal master key ciphertext in IC-card for POS terminal, obtain terminal master key expressly, be saved in POS terminal password keyboard, thereby realize POS terminal and POS, receive the synchronous of terminal master key between single system.
Above-mentioned two schemes has following shortcoming: terminal master key expressly appears at outside safety equipment, and for taking precautions against Key Exposure risk, the safe machine room that the download of terminal master key must be controlled at administrative center carries out, by the artificial download terminal master key of concentrating.Thereby bring, " maintenance centre's machine room workload is large; After equipment dispatches from the factory, need to be transported to administrative center's safe machine room download key and just can be deployed to trade company, transportation cost rises; In order to concentrate lower dress key, need a large amount of staff and working time, maintenance cost is large, maintenance period is long " etc. problem.
