摘要: 提出一个基于离解对数与二次剩余问题的高效自适应分布式密钥生成方案,在保证密码系统公私钥对不发生变化的前提下, 通过刷新各个组成员的公开参数,实现成员的动态加入与退出,同时各组成员的子密钥可以重复使用,提高密码系统的工作效率。

Abstract: This paper proposes an efficient and adaptive Distributed Key Generation(DKG) scheme based on discrete logarithms and quadratic residue problem. It is able to dynamically add and remove members from the group by refreshing the public parameter without altering the public key. The sub-keys of each group members can be reused. It improves the efficiency of the cryptographic system.

Key words: Distributed Key Generation(DKG), discrete logarithms, quadratic residue
