An improved confirmer digital signature scheme

Abstract

An improved confirmer digital signature scheme was presented based on the analysis of the disadvantages of traditional confirmer signature algorithm and the introduction of zero-knowledge proof. In this scheme, signer need not directly provide his signature to the information, he just need to provide a zero-knowledge to prove that he has the information signature. This zero-knowledge proof includes the signer's identity information. Compared with the traditional confirmer signature algorithms, the improved scheme is simpler and more efficient, and has higher security.
