摘要
基于NTRUSign数字签名方案,构建一个新的群签名方案。该方案的安全性基于格上的最近向量问题,并对该方案进行了详细地安全性分析。结果表明该方案满足一个群签名方案应具有的性质,且实现速度快、占用资源少以及产生密钥容易,具有更高的实用性和安全性。
A group signature scheme based on the NTRUSign is proposed, the security characters of this scheme are analyzed.It shows that the scheme own some essential character that a group signature should have, and have the advantage of high implementation speed,save computer resources and easy key creation.This scheme is applicable and secure.
