摘要
基于椭圆曲线密码系统的优势,设计了一种群签名方案。方案从群签名的初始化、签名过程和验证进行了详细的研究和设计,并且使用了目前最新的杂凑函数SHA-3,增强了签名的安全性。最后分析了该方案的特性,与以基于RSA等通用签名算法进行比较,该方案在效率和安全性方面具有较好的性能。
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.
