群签名方案之比较研究

Comparative Research on Group Signature Schemes

回顾了群签名理论研究的发展过程,列举了群签名发展史上一些最主流的算法,并对它们的性质、优缺点作了较为深刻的比较研究。最后提出:设计好的方案固然重要,但当设计十全十美的方案比较困难时,不能因此而放弃其实际的应用,可针对具体的应用环境对某些指标的特定要求采取适合该环境的方案。

In this paper, we review the development ol the research on group signature and we list the most popular and important schemes in the history of group signature theory. We analyze the property of these schemes and point out their advantages and disadvantages. Finally, we make a conclusion： we can change our mind from trying very hard to find a good scheme to the point of finding an appropriate scheme for the different context.
