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...
Hash chains are widely used for entity authentication or data-origin authentication. However, finite length of a hash chain limits its implementations. A new kind of hash chain, called self-renewable hash chain (SRHC) is proposed, which achieves a hash chain self-renewing or re-initialization smoothly, securely throughout its usage. The renewing process of SRHC does not need additional protocols or...
