Digital Certificate-based Authentication Technology Research

With the rapid development of Internet technology, information and continuous improvement in the level, on-line government and online business as a new mode of communication, is widely used, since April 1, 2005 began implementing the "People's Republic of China Law on Electronic Signatures "Since the identity of digital certificate-based authentication in a variety of authentication methods is receiving increasing attention to the protection of Web applications has become a security authentication options.Web-based applications on the application of the identity of the subject put forward higher requirements of the construction of identity is the way it is particularly important, how to create a safe, advanced, convenient on-line authentication services, in accordance with the law for the main application to provide reliable technical support, Internet governance and the healthy development of online business as a key issue.Through dynamic password, digital certificates and single sign-key technology, the realization of a unified identity management, so that a user can only be reached authentication system for access to multiple applications, increased user productivity, and enhance system security, reduce the heavy administrative burden. In this paper, we have adopted a dynamic password based on the matrix card technology to enhance access control of digital certificates in order to achieve the client digital certificate, two-way authentication server to improve the system security, reducing client costs, a better solution to the customer service-oriented distributed environment WEB unified authentication problem.
