That is, when a user wants to remotely access the service provided by a server, he/she first registers with the service provider.

In this paper, we propose a new strong-password authentication protocol that not only can withstand many possible attacks including a stolen-verifier attack, but that is also more efficient than the modified OSPA protocol.

However, this also makes the scheme vulnerable to offline password guessing attack, especially when the verification table is disclosed.

To conquer this issue, smart card is introduced into the design of password-based authentication scheme, which results in password and smart card based two-factor authentication scheme.

Particularly, these schemes are designed for the single server environment.
