摘要 结合无证书签名和盲签名的特点,提出一个新的无证书盲签名方案,以简化传统公钥密码体制的密钥管理过程,解决基于身份的公钥密码体制存在的密钥托管问题。分析结果表明,该方案在随机预言机模型、q强Diffie-Hellman困难假设和逆计算Diffie-Hellman困难假设下满足盲性、不可追踪性和不可伪造性,且签名的产生和验证过程仅需一个对运算,具有较高的效率。 In order to simplify the certificate management process of the traditional public key system and solve the problem about private key escrow in the identity-based public key system,this paper proposes a new certificateless blind signature scheme which combines certificateless signature and blind signature.Analysis result shows that the new scheme is blind,untraceability and unforgeability in random oracle model and under the q-strong Diffie-Hellman complexity assumption and the inversed Diffie-Hellman complexity assumption.The signing algorithm does not require any pairing computation and the verification algorithm only needs a pairing computation,so that the scheme proposed is more efficient.
