Fair Signature of Knowledge
Bao Li · Journal of Wuhan University · 2008
Traditional definition of signature of knowledge can not prevent steganographic communication.To solve this problem,we introduce and formally define the notion of fairness of the signature of knowledge.We then construct a fair signature of knowledge scheme by use of fair zero-knowledge proofs of knowledge,and finally prove that this scheme indeed guarantees the fairness and can efficiently prevent steganographic communication.
