Embodiment

[0029] For an application system that implements a multi-point deployment strategy, there are multiple copies of key information storage (physical or logical) in a system, and online transaction processing is distributed to each node through load balancing technology (bank card transaction front-end equipment 200a, 200b, 200c), and the occurrence frequency and time interval of online transactions are irregular, which requires that the key information on each storage node in the system must be kept strictly available at all times , therefore, high requirements are placed on the process of its update synchronization.

[0030] In the banking system (such as figure 2 The bank mainframe 300 in) and UnionPay system (such as figure 2 In the communication of the key source server 100 in ), an online transaction will be transmitted in three parts, including the UnionPay server, the front-end system of the bank (such as figure 2 The bank card transaction front-end equipment 200a, 2...

Abstract

The invention discloses a secret key synchronization method of bank card transaction preposition equipment and a system thereof. The system comprises: a secret key source server, a bank host and a plurality of bank card transaction preposition equipment. The secret key source server is respectively connected with a plurality of bank card transaction preposition equipment. The bank host is respectively connected with a plurality of bank card transaction preposition equipment. Each bank card transaction preposition equipment comprises: a secret key reset request receiving apparatus, a secret key reset request processing apparatus, a secret key reset request sending apparatus, a secret key reset response receiving apparatus, a synchronous updating instruction generation apparatus, a synchronous updating instruction sending apparatus, a secret key downloading request sending apparatus, a secret key downloading response receiving apparatus, a secret key local updating apparatus, a synchronous updating response receiving apparatus and an encryption / decryption processing apparatus. By using the method and system of the invention, before secret key synchronization updating, during the secret key synchronization updating and after the secret key synchronization updating, the each node preposition equipment of the bank card transaction preposition equipment can perform correct encryption and decryption processing to online data.

Description

technical field [0001] The invention relates to the technical field of key synchronization in computer network communication, in particular to a key synchronization method and system for bank card transaction front-end equipment. Background technique [0002] In the prior art, bank card transactions between commercial institutions such as banks generally communicate through the UnionPay system. Banks generally deploy a front-end system between the bank host and the UnionPay server, which acts as a transfer system between the bank host and the UnionPay server to realize functions such as message conversion, encryption and decryption. [0003] The transaction volume between a large bank and UnionPay may reach hundreds or even thousands of transactions per second. Therefore, the front-end system bears huge transaction pressure, and often adopts a multi-point access deployment strategy to achieve multi-channel concurrency and load Balanced and online mutual backup, thereby grea...
