Identity authentication is a technology that when a user logs in a system or accesses system resources of different protection levels, the system confirms whether the identity of the user is real, legal and unique. Most of the existing identity authentication methods during login are based on user names and passwords, and the security can be ensured only by setting complex passwords. However, the password is too complicated and is not easy to memorize, so that potential safety hazards of inconvenient management and the like exist.
Digital certificate-based authentication is one of the basic security services provided by public Key infrastructure, pki, (public Key infrastructure). PKI is based on asymmetric public key technology, and binds digital information such as user natural identity and public key together by using digital certificate, and is an authentication mode for uniquely representing user identity in various network applications.
