Cross-domain single sign-on authentication of information security in network environment

Aiming at the problems of long response time, poor security and information integrity in cross-domain single sign-on authentication research of network security, this paper proposes a cross-domain single sign-on authentication method based on SAML, including the design of login authentication control and revocation authentication scheme. In login authentication, efficient interaction between identity providers and service providers reduces unnecessary steps to achieve single sign-on. At the same time, a revocation scheme based on cumulative function is proposed to ensure that the local root signature is used for system parameter information, thus further ensuring network security. The experimental results show that the login time of the proposed method is below 400 ms, and the login response takes a short time. The success rate of the proposed method against false login is over 90%, and the security is good. The data packet loss rate of this method is below 2%, high integrity and reliability.
