Abstract:

With the increasing management information systems, a security identity authentication system is urgently needed to realize single signon. The paper does some research on the mechanism of CAS by analyzing different identity authentication technologies and then analyses the working principle of CAS and its security. For the existing security problems, a mixed dynamic encryption algorithm which combined with a variety of encryption algorithms is proposed. In addition, the random number and time stamp are used in the algorithm to enhance the security of the system.
