中文摘要: 为满足实际应用中对于安全高效代理盲签名的需要,基于双线性对映射提出了一个新的无证书代理盲签名方案。方案中对相关参数进行预先计算,并作为系统公开参数发布,签名生成过程无须进行双线性对的运算,与现有同类算法比较,具有更高的计算效率,在实际应用中更具优势。在随机预言机模型和双线性Diffie-Hellman困难性假设下,证明了本文方案在2类攻击者适应性选择消息攻击和身份选择攻击下是存在不可伪造的。
Abstract:To meet the application requirement of proxy blind sign,a new certificateless proxy blind signature scheme based on paring was presented.Through the pre-calculation of the parameter which is published as one of the system parameters,the new scheme does not require any pairing computation in the sign step.The comparison with other schemes in the literature showed that it is more efficient has advantages in practical application.The scheme was proved to be existentially unforgeable against Type Ⅰ or Type Ⅱ adaptively chosen message and identity adversaries in random oracle model,under the bilinear Diffie-Hellman assumption.
