Research On PKI Secure Access System

With the development of internet, many traditional works can be done on internet, improving people's working efficiency and the quality of life. For the openness and anonymity, there are many hidden risk of security on internet. It is important to keep information secure including the security and integrality on information transmitting,the reliability of identity authentication and some other secure measures. Various kinds of technology, including encryption, digital signature, firewall, VPN, etc, are required to provide an end-to-end security and to prevent information from leaking, therefore many questions can be efficiently solved such as the confidentiality, the authenticity, the integrality, the access control and so on. A system of secure interface based on PKI is proposed in this paper.Based on systemic model of information security, a system of secure interface based on PKI is proposed in this paper. Some questions are discussed in detail such as the functions, structure of the system. This program is between user and application system, running on application layer, and could extends kinds of existing commercial application system securely to the Internet and Intranet. Access authentication is mainly designed and implemented including secure transmission based on SSL protocol and identity authentication based on UKey and PKI. So authenticity and privacy protection are efficiently realized in this sub-system.In this paper, various kinds of secure technology are introduced and their characteristic and merits are depicted as a whole firstly. Then the structure of the digital certificate and encryption is described in detail, and at the same time the corresponding solution are given in this paper. Finally, based on our own research results, we put forward the developing trends and main research direction.
