摘要 可验证加密签名方案的公平性完全由仲裁者中立问题决定,这样就降低了交换签名的安全性。为了应对这种情况,利用双线性对的性质,结合无证书公钥密码体制与可验证加密数字签名,设计了一种盲化的基于无证书的可验证加密签名方案,方案中的仲裁者不能直接恢复原始签名,从而加强了交换签名的安全性。在假设离散对数问题(DLP)和计算Diffie-Hellman问题(CDHP)难解的前提下,该方案在随机预言模型中是可证安全的。 The fairness of verifiable encrypted signature scheme is completely determined by the arbitrators neutral problem, which reduces the security of signature exchange. In order to deal with this issue, using the properties of bilinear pairings and combining with certificateless public key cryptography and verifiable encrypted signature, a blind verifiable encrypted signature was designed without certificate. The adjudicator in this scheme cannot restore the original signature directly, thereby the security of exchange signature protocols was enhanced. The proposed scheme was also provably secure in the random oracle module under Discrete Logarithm Problem （DLP） and Computational Differ-Hellman Problem （CDHP） assumption.
