| 摘 要： | 目前大部分的群签名方案中,群公钥的长度和群成员数至少是线性关系,因此在群成员很多时,这类群签名方案很难适用。本文提出一种从代理签名演化而来的新的群签名方案,能够解决这一问题,并且本方案所采用的循环群的阶为一公开参数,群公钥长度固定。

| Abstract: | In most group signatures,the length of group public key has linear relation with the number of group member at least,so it is hard to adopt such schemes when the number of group member is large.This paper proposes a new group signature scheme derived from a proxy signature scheme which can solve the above problems,and the order of cycle group adopted by this scheme is a public parameter,and the length of group public key is fixed. |

| Keywords: | group signature proxy signature cycle group |
