The Research And Analyzing Of PKI Based Identity Authentication

As the gradual improvement of the network and information's application all over the world, the security of information and integrality of data become more importance, regular identity authentication technology as its own security flaws is no longer adapted to the high security network applications. Nowadays, public key infrastructure, which supports secure service such as identity authentication and encryption, become hotspot in the area of information security research.The paper analyses PKI and related technologies based on the theory and structure of PKI and summarizes the technology for network security service. Then, it introduces the advantages and the disadvantages of several identity authentications which are currently using popularly and prospects of the development trend of identity authentication technology. Combining with the security problem in Internet application and the character of mobile communication, the paper propose a kind of unified end to end identity authentication schema in the application domain of mobile network. This schema which identity authentication based on wireless PKI and channel encryption adopted WTLS protocol in the process of data transmission provides many kinds of service.The paper focuses on the user's digital certificate management solutions, combines the SD Key and smart card technology to optimize the storage function of certificate.
