摘要: 设计了一个基于身份无需可信任PKG的聚合签名方案,并且在随机预言模型下证明了方案可抵抗适应性选择消息和身份的存在性伪造攻击。方案通过将两部分密钥绑定于同一身份的方法解决了密钥托管问题,且与已知的一些方案相比,新方案提高了计算效率。

Abstract: An efficient ID-based aggregate signature scheme without trusted PKG is proposed.The proposed scheme is secure against existential forgery under adaptive chosen message and identity in random oracle mode.The scheme solves the key escrow problem through binding two parts of keys with a same identity.And the efficiency of the scheme is higher than the existing schemes.
