Abstract
Based on the advantage of the elliptic curve cryptosystem,a group signature scheme is designed.The design scheme is carried on from the detailed process of initialization,signature and verification of the group signature; after that,the SHA-3 of current latest hash function is used,which enhances the security of the group signature.According to the aboved research,the paper analyzes the characteristics of the scheme,and the analysis results show that the scheme has better performance in terms of efficiency and safety than signature algorithm based on RSA etc.
