【摘要】 分析了适用于资源受限和需要隐私保护环境的安全的无证书聚合签名方案的安全性。通过对Wang等提出的一个适用于智能电网的轻量级计算的无证书聚合环签名方案进行安全性分析，分析结果表明该方案至少会受到3种类型攻击(替换公钥攻击、恶意KGC攻击和任意攻击),并给出了具体的攻击方法，分析了存在这些缺陷的原因。研究结果对同类签名的设计与分析具有借鉴意义，可避免出现类似的安全性问题。更多还原

【Abstract】 The security of certificateless aggregated signature scheme for resource-constrained and requiring privacy-protected environments is analyzed.A security analysis is conducted on a certificateless aggregate ring signature scheme recently proposed by Wang et al for lightweight computation in smart grids. The analysis results show that this scheme is vulnerable to at least three types of attacks: public key replacement attack, malicious KGC attack, and arbitrary attack. Moreover, specific attack methods are presented, and the reasons for these defects are analyzed. The research results can be used as a reference for the design and analysis of similar signatures, and similar security issues can be avoided.更多还原
