The Network Key Mechanism Based On Client Signature Of Huafu Securities Network Transaction System

The convenience and security were the characters of financial business enterprises of network payment in the background for the development of e-commerce. Therefore, the establishment of a unified, perfect, intensive network of financial trading, futures trading, credit trading platform, to achieve between the different individual and different transaction subject information flow, capital flow real-time intercommunication is inevitable trend of the development of electronic commerce.The security management of Key system was the one of the conclusive factors for the securities trading system. The development, operation and management of Key system were accompanied by its design and maintenance, and the series process of generation, update, store, use. Therefore, the systematic study of Key system was helpful to the security level and management efficient of entire encryption system.The tendency of internet securities trading required the high security and functional trading system. The PKI mechanism(Public Key Infrastructure) had been widely used in internet securities trading system, and provided entity authentication for information transmission and transactions. It was in order to protect the integrity and security of information during the transaction process.PKI system was a strong derivative key encryption system, and its specific encrypt forms were complex and diverse. No complete and standardized encryption were the characterized of PKI system. Therefore, the discussion on PKI system must be rely on entity internet securities trading.In this thesis, HuaFu securities trading system was used as the research object, and the mechanism of PKI was the target to searched in the substantive securities. The secure key generation, key management, security auditing and other properties of passwords were measured comprehensively of the encryption mechanism in HuaFu securities trading system. And the explore to PKI mechanism of HuaFu securities trading system was designed to personal digital signatures. In our study, we combined digital signature and PKI mechanism, and recorded the transmission data, ensure the securities transaction remain safe and reliable internet environment.
