一种基于二次剩余的群签名方案
Group Signature Scheme Based on Quadratic Residues
摘要
Abstract
Group signature has been positive regarded for its wide application, however, dynamic member joining algorithm is complex yet in many of the existing schemes. This paper analyzes the identity-based signature scheme based on quadratic residues proposed by Chai et al and the improvement scheme of literature [ 1 ] , and shows that the improvement scheme is not provable security. This paper also presents a group signature scheme using the scheme proposed by Chai et al and existing converting method. The scheme can effectively solve the dynamic member joining of group signature effectively.关键词
