Abstract: This paper constructs a set of cryptogram security system for rural credit cooperatives based on domestic cryptographic algorithm. It transformed general cryptographic algorithm into domestic cryptographic algorithms for the system of corebank, frontbank, online bank, financial IC card and the second generation payment etc., which involved cryptographic applications. It solved the security problems of identity authentication, information integrity, repudiation and so on. It provided a secure and reliable cryptographic guarantee for the rural credit cooperatives. It enhanced selfcontrollable ability of information security core products and system for rural credit cooperatives, and improved the safety and security capability of rural credit cooperatives. It has a great significance to the popularization and application of domestic cryptographic algorithms.

Key words: domestic cryptographic algorithm, cryptographic service platform, key management system, data preparation system, host security machine
