对一种基于身份环签名方案的安全性分析
On the Security of an Identity-Based Ring Signature Scheme
摘要
Abstract
The security of the identity-based ring signature scheme of [18] is analyzed in this paper. It is found that this scheme did not possess the unforgeability property. It is also shown that the proposed scheme is insecure against a new kind of forgery attack, i.e. the identity assembly forgery attack. With such an attack, an adversary is able to forge valid ring signatures on any message based on the features of its identity, and the identity of the adversary can be even not included in the ring of the forged signature.关键词
