A New Fuzzy Digital Signature Scheme
Shihui Zheng · Jisuanji gongcheng · 2006
The concept of fuzzy signatures allow two entities to produce two signatures in such a way that,from the point of view of any third party,both signatures are ambiguous with respect to the identity of signing party until an extra piece of information is released by one of the parties.This paper designs a new fuzzy signature scheme based on the discrete algorithm problem.From this concurrent scheme,it proposes a signature protocol in which the signature can be fairly exchanged between signers.
