Improvement of Li-Hwang's Biometrics-Based Remote User Authentication Scheme Using Smart Cards

Password authentication is one of the mechanisms that have been widely used to authenticate a legitimate user. If the remote users want to login to a remote server for its resources and services, they must be authenticated by the remote server first. In 1981, Lamport first proposed a remote user authentication scheme by using a one-way hash chain and password table. However, if the password table is stolen by an adversary, all of the remote users must change passwords and/or re-register.
