Research and Design of CAS Protocol Identity Authentication
HaoYuan Zhou, Ligu Zhu · 2020
With the rapid development of science and technology today, in the face of a variety of different systems, the use of a secure, unified and efficient authentication system can not only simplify the workload of administrators, but also simplify the memory of users and ensure the security of user data. We studied the advantages and disadvantages of several existing authentication methods. In order to facilitate multiple systems to achieve unified authentication login, we choose to use CAS to realize SSO's single sign-on function. It enables multiple subsystems to share a safe and reliable login method, and users can switch access freely among multiple subsystems. At the same time, in order to avoid the disadvantages caused by user's simple password, we improved the CAS encryption method with a small part of the custom encryption method. Some opinions and suggestions are put forward on the problem that single point of logout does not destroy session and users can log in after logout.
