In this paper, two password authentication schemes with smart cards are proposed. In the schemes, users can change their passwords freely, and the remote system does not need the directory of passwords or verification tables to authenticate users. Once the secure network environment is set up, authentication can be handled solely by the two parties involved. For a network without synchronized clocks, the proposed nonce-based authentication scheme is able to prevent malicious reply attacks.
