An efficient authentication scheme based on the self-updating hash chain for campus network

A novel authentication scheme with self-updating hash chain is proposed for campus network, which realizes efficient identities authentication using the cryptographic features of hash chain. The self-updating hash chain solves the length limitation of traditional hash chain. Analysis are given to illustrate the proposed protocol is secure and efficient. Practical implementation show the given scheme is available and feasible. At last, the achievement of authentication server is stated.
