The data centralize already become our country banking industry's main development tendency, As the most policy-type bank of china, ADBC(the Development Bank of China) also promoted own Intergrate Business System at the right moment.This dissertation has mainly lain in for the Intergrate Business System designs set of securities, credibility and conforms to ADBC actual security subsystem. There are two kinds of important information security technology to be analyzed in this thesis: Data Cryptography and PKI technology.The dissertation proceeds with the whole structure of Intergrate Business System of ADBC, introduces the outlines of physical structure and software structure of the Intergrate Business System for ADBC. On the basis of above, The dissertation analysed the risks of the Intergrate Business System of ADBC, and depended on the security needs of ADBC research and the goals of system design made Intergrate Business System security subsystem design principles. Then, researched the key of security system: the principle of IDEA, DES, RSA, MD5 and analyzes their security. Discussed the content and the server of the PKI system, combining smart IC card technology research presented security subsystem solutions. In base of the discuss of the whole structure of security subsystem, introduced separately the design for security on the counter systems ^ payment systems and transaction server, and then given on the basis of security subsystem solutions corresponding software modules. Finally, the deficiencies described in the programme analysed and presented in the future need further improvement.Currently, Intergrate Business System of ADBC has online operation, the programme has been chairman of this implementation.
