Embodiment 1

[0038] figure 1 It is a schematic diagram of the bank terminal security device key management system according to the present invention. Such as figure 1 As shown, the bank terminal security device key management system according to the present invention includes a banking terminal 1 and a banking back office 2. The banking terminal includes: a business application system client 3, an encryption service interface 4, a bank terminal security device 5, and a key management agent component 6. The banking business backend includes: KMC (Key Management Center) 8, a key database 11, a first encryption machine 10, a second encryption machine 12, an encryption service interface 9 and a business application system server 7, wherein the key management agent The components are unique to the present invention. The functions and relationships of the components in the bank terminal security device key management system are as follows: the bank terminal security device has key storage and cr...

Embodiment 2

[0041] Hereinafter, the key management method of the bank terminal security device according to the present invention will be described.

[0042] figure 2 It is a schematic diagram of a key management method for a bank terminal security device according to the present invention. Such as figure 2 As shown, the bank terminal security device key management method according to the present invention is divided into three major steps: terminal security device registration, terminal security device key automatic issuance, and terminal security device key automatic update, which are described as follows:

[0043] 1. Terminal security device registration

[0044] The work completed in this step is to register the terminal security device in the KMC (Key Management Center), and write the master key (used to encrypt the work key) into the bank terminal security device. After that, the bank terminal security The device generates a working key (used to encrypt data) in advance. The detailed...

Embodiment 3

[0061] In order to explain the present invention more clearly, in the following, the bank terminal security device key management method according to the present invention will be described in more detail in conjunction with the operating environment of the bank terminal security device key management system according to the present invention.

[0062] Similarly, the bank terminal security device key management method according to the present invention includes three steps: terminal security device registration, terminal security device key automatic issuance, and terminal security device key automatic update. Among them, the terminal security device can be a bank counter PIN keyboard, ATM, etc.

[0063] 1. Terminal security device registration

[0064] The terminal security device registration is completed by the cooperation of the terminal security device, key management agent component, KMC server, key database and encryption machine. At present, banks generally have KMC. If the ...

Abstract

The invention relates to a key management system and a key management method for bank terminal security equipment. The system comprises a bank service terminal and a bank service background; the bank service terminal comprises the bank terminal security equipment and a key management agent component; and the bank service background comprises a KMC, a key database, an encoder and a service application system server, wherein the key management agent component is used for acquiring a working key from the KMC and writing the working key into the bank terminal security equipment; and the KMC provides registration service, key transmitting service and automatic key update service for the bank terminal security equipment. The key management system and the key management method for the bank terminal security equipment can effectively realize key management of the bank terminal security equipment, and separate the key management from a bank service application system at the same time so that each service application system does not need to implement complex key management logics any more and the implementing complexity of the service application system is reduced.

Description

Technical field [0001] The invention relates to a bank terminal security equipment key management system and method. Background technique [0002] When people do transactions at the bank counter, ATM, and POS, they need to enter the bank card password. In order to ensure the security of the card password and transaction information, the bank counter password keyboard, ATM, POS and other terminal security devices use encryption technology for card passwords and transactions Information is encrypted. The encryption technology itself is relatively mature, but the management of the keys used for encryption is complicated and tedious. Terminal security device key management includes key generation, key issuance, key update, etc. The current bank management method is: the issuance and update of terminal security device keys are designed and implemented by each business application system itself, such as cabinets The business application system needs to design and implement the key is...
