In the previous multi-group signature scheme of G.Ateniese and G.Tsudik’s, the main disadvantage was the use of the inefficient signature of knowledge protocol to prove the equality of two double discrete logarithms. To over come this shortage, two improved multi-group signature schemes were made in this paper, building on more efficient signature of knowledge protocols. The security of the new schemes was analyzed quite sufficiently in the random oracle. Moreover, the efficiency of the new schemes was compared with the original scheme using specific parameters. Additionally, an improved sub-group signature scheme of G.Ateniese and G.Tsudik’s was also proposed. It can be proved that all the proposed schemes possess better security, efficiency and practicality.

多群签名方案是对普通群签名方案的一种推广。如何构造安全、高效的多群签名到目前为止还是一个未解决的问题。该文对G.Ateniese和G.Tsudik提出的多群签名方案进行了改进,且构造过程无需借助基于两个双重离散对数相等的知识签名。通过较为充分的安全性分析及执行效率的比较,可以看出新方案具有更好的安全性、有效性和实用性。最后还提出了一个安全、高效的子群签名方案,其效率较G.Ateniese和G.Tsudik提出的子群签名方案也有显著提高。

In this paper,a secure multi-groups signature scheme is presented based on Kim et al.'s convertible group signature schemed.The new scheme can realize the single-group and the multi-groups signature,and can withstand the attacks proposed by Li.and Wang et al.to Kim et al.'s scheme.Furthermore,the new scheme provides a solution for deleting the members from a group or multi-groups.

基于K im等人的可转换群签名的思想,提出了一个安全的多群签名方案.该方案不仅能实现单群签名,而且能实现多群签名,并且能抵抗L i和W ang等人对K im等人方案提出的攻击.此外,新方案还具有注销群成员的特性.
