Proposed a new multi-user authentication system. The user password is a combination of a variable password and a fixed password. The authentication uses dynamic passwords, attack thresholds and synchronous encryption. The purpose of the system design is to simultaneously resist the awkwardness and exhaustive attacks, with high security and certain practicality.
