Terminal ID Authentication System Based on Digital Certificate

System security login and ID authentication are the first level in the security system, and the basis for implementing access control, which plays a very important role in the field of system security. This paper mainly introduces a terminal ID authentication system based on digital certificate. Through this authentication mechanism, the server can identify whether the real identity of the user is consistent with its claimed identity and prevent illegal users from invading the Web application system. Using digital certificate to encrypt authentication information can effectively prevent network eavesdropping. Using digital certificate to complete mutual authentication between users and servers and using challenge response to realize the function of one secret at a time. By using the signature and signature technology of data certificate, the non-repudiation of information can be achieved, and the non-repudiation of electronic data sharing and transmission can be ensured by electronic means. After the deployment and testing of the single sign-on system, the system runs stably and achieves the expected effect.
