摘要
可在不同群组间共享的、满足安全性要求的、有效的群签名方案是近来群签名研究的一个重要方面。基于离散对数的群签名方案允许不同群组可以共享系统公开参数,使用零知识证明的主要思想,充分保证了方案的安全性和有效性。共享方案可为不同群组间建立一个统一的安全的体系结构提供理论支持,有利于群签名方案的应用和管理。
New group signature schemes that are secure, effective and shared among different groups are an important direction in researching. The group signature scheme based on discrete logarithm problem can be used to share public parameter of the system among different organizations. Further, the main idea of the zero-knowledge proof is used to guarantee the security and efficiency of the scheme. Such sharing represents a high support for a uniform and secure system construction, and is favor to the management and application of the group signature system.
