A self-renewal hash chain scheme based on fair exchange idea(SRHC-FEI)

In this paper, we proposed a self-renewal hash chain scheme based on fair exchange idea for the first time. Our authentication scheme is mainly concerned about the shortcomings of the traditional hash chain schemes. It combines with OTS(One-Time Signature) so as to realize mutual-authentication, anonymous-authentication and self-renewal of hash chain simultaneously. From the results of analysis, we may indicate our scheme has many good properties that a good authentication scheme should have.
