一种具有多种功能的环签名方案

摘要

在对称密码实体认证上的基础上,将可链性、时间戳、哈希链、加盐、双线性对、比特承诺等概念引入环签名,使其成为一种具有多种功能的环签名方案。在具有了多种功能的前提下,新方案的安全性增强了,而相应的复杂度却没有增加。%This article introduces concepts such as chain nature,timestamp,hash chain,salt,bilinear right,bit commitment into the ring signatures as a introduction based on the entity authentication in symmetric cryptography,thus making a multi-functional ring signature program with enhanced security,while the corresponding complexity is not increased.
