Bank Secure Online Transaction System Based On Pki Technology

Banking computer network information security in the national life is an increasing concern, because: many important financial information stored on the network, once the information leak, enterprises, and individuals will result in incalculable damage. Network information will be leaked, on the one hand there are many invaders do everything possible to "see" some concern to the data or information other network security risks exist. Therefore, how to ensure that the banking network environment information authenticity, integrity, confidentiality and non-repudiation has become the field of information security and e-commerce on the main issues. In light of these problems, the paper summarized a number of network information security technology and the protection methods and strategies.PKI (Pubic Key Infrastructure, based on public key) technology, used in modern cryptography established on the basis of digital certificates, CA and Certification Center, network communications encryption protocol, for different users by providing a wide range of different security needs of security services, Better for this lesson provide a solution. In the study of the PKI technology on the basis of this paper on the basis of PKI technology, security systems, technology core CA and Certification Center, the trading system design, transaction encryption protocol process, made a detailed exposition. According to the practical application of technical requirements, design and realization of a system based on the PKI system of Internet banking transactions.
