For conventional dynamic password authentication protocols (such as S/KEY, SAS, etc), the algorithm of generating a new password basically uses either two neighboring passwords or authentication factors. The relevance of the passwords can be unveiled during the protocol execution and thus vulnerable to be attacked. In this paper, a new method is proposed. This method uses indirect authentication information as an interference factor to protect authentication password and safely accomplish the authentication process.
