无证书聚合签名方案的分析

Analysis of a Certificateless Aggregate Signature Scheme

本文分析了无证书密码方案,结合Nie等人提出的一种无证书聚合签名方案分析了无证书聚合签名的框架和安全模型,并对该进行了分析,指出该方案是不安全的,即不能抵御I型对手的攻击并进行了论证。

This paper discussed certificateless cryptography scheme.The framework and security model of certifcateless aggregate signature is discussed by analyzing the certificateless aggregate signature scheme proposed by Nie et al.It is proved and revealed that the scheme is not secure and it can not resist the attack of type I adversary.
