Embodiment Construction

[0044] In order to understand the content of the present invention more clearly, it will be described in detail with reference to the drawings and embodiments.

[0045] The first aspect of the present invention relates to a process flow such as figure 1 The encryption method for data transmission processing of credit card validity period shown includes:

[0046] S1. Set data usage points respectively according to usage requests of all credit card validity period data. The optional data usage points include client, bank personnel, external data, credit card core, data storage, credit card security, and other systems and clients that all involve the use of credit card validity period data. In this step, the difference between each data use point is not specifically defined, especially the difference in security permissions during verification, but only provides the necessary basis for the subsequent steps.

[0047] S2. Assign a unique security number to each data usage point; ...

Abstract

The invention relates to the technical field of automatic program design and information verification, in particular to a credit card validity period data transmission processing encryption method and system. A security number is used to establish a data transmission relationship, a point-to-point encryption and decryption key and a local symmetric encryption and decryption key are allocated to encrypt and decrypt credit card validity period data, and point-to-point encryption and local symmetric encryption are combined to realize encryption requirements of each working node during data transmission and processing of the credit card validity period data, so that on the premise that existing services are not affected, rapid safety management can be achieved, and safety specifications are met.

Description

technical field [0001] The invention relates to the technical field of automatic program design and information verification, in particular to a credit card valid period data transmission processing encryption method and system. Background technique [0002] In the C3 field defined in the PBOC's "Personal Financial Information Protection Security Specification", a new bank card validity period has been added. Since there is no bank card validity period in the C3 field in the previous specification, when implementing the credit card system, the fields of the credit card validity period type are handled as ordinary business fields, and are used in customer channels, employee channels, data lines, transaction links, file exchange, etc. Both links and links are processed in plain text without special processing. For the existing credit card system, the validity period of the credit card is processed as ordinary business data, and both the transmission layer and the storage laye...
