摘要： 指定验证者签名方案可以保护签名者的个人敏感信息不被泄露。利用该方案的优点，基于随机预言模型中的困难性假设，提出一种可证安全的具有指定验证者的代理签名方案。理论分析证明，该方案满足可验证性、强不可伪造性、强不可否认性和限制验证性，并能抵御重放攻击。

Abstract: Designated verifier signature scheme can protect signer’s personal sensitive information not be revealed. Taking advantages of the scheme and based on random oracle model of the difficulty assumptions, this paper proposes an efficient proxy signature scheme with designated verifier. Theoretical analysis shows that the scheme can meet the verifiability, strong unforgeability, strong undesirability, and designated verification, meanwhile, and it can resist replay attack.
