摘　　要：基于证书公钥密码体制克服了已有密码体制下的证书管理问题、密钥托管问题以及对可信第三方的信任级别低的问题,指定验证人签名可以达到防止因数字签名被任意传播导致签名人隐私被泄露的问题。在基于证书的公钥密码体制的基础上,构造一个基于双线性对的基于证书指定验证人签名方案。The certificate-based public key cryptography system can overcome the certificate management problem, the private key escrow problem and low credibility for the trusted third-party problem. Designated verifier signature can solve the problem of signers＇ privacy leak-out which is caused by the spread of digital signature. Based on certificate-based public key cryptography system, we construct a certificate-based designated verifier signature scheme based on bilinear pairings.
