| 摘 要： | 基于双线性映射，结合指定验证者签名和代理签名的优点，提出具有指定验证者的无证书代理签名方案。该方案无需使用公钥证书，可以解决基于身份签名方案固有的密钥托管问题，保护签名者的私人信息，并允许在原始签名者无法进行签名时由代理签名者进行签名。理论分析结果表明，该方案能够满足指定验证者代理签名的安全要求，具有较高的效率。

| Abstract: | Based on the bilinear pairing and combining with the advantages of designated verifier signature and proxy signature,certificateless proxy signature with designated verifier is proposed.Certificateless signature schemes do not need the public key certificates and effectively solve the inherent key escrow problem in identity based signature schemes.The designated verifier signature can protect some sensitive information of the signer.The proxy signature allows the proxy signer sign the information instead of the original signer who can not do that.This scheme can satisfy the requirements of the certificateless designated verifier proxy signature and has high efficiency. |

| Keywords: | certificateless cryptography key escrow proxy signature designated verifier signature bilinear pairing hash function |
