Sequence Patterns of Identity Authentication Protocols

From the viewpoint of protocol sequence, analyses are made of the sequence patterns of possible identity authentication protocol under two cases： with or without the trusted third party （TFP）. Ten feasible sequence patterns of authentication protocol with TIP and 5 sequence patterns without TFP are gained. These gained sequence patterns meet the requirements for identity authentication, and basically cover almost all the authentication protocols with TFP and without TFP at present. All of the sequence patterns gained are classified into unilateral or bilateral authentication. Then, according to the sequence symmetry, several good sequence patterns with TFP are evaluated. The accompolished results can provide a reference to design of new identity authentication protocols.
