Abstract: In some applications, original signer hopes that the designated verifier can verify the validity of the signature. This paper proposes a novel designated verifier signature. The new scheme not only realizes the property with designated verification, but also the property that only designated verifier can recover the message. The result shows that the new protocol realizes the secure signature with designated verification.

Key words: cryptography, signature, designated verifier, message recovery, bilinear pairings

摘要: 在有些应用中,原始签名者希望只有指定的验证者才可以验证签名的有效性。基于双线性对密码体制提出了一种新的指定验证者签名方案,新方案不仅实现了签名的指定验证性质,而且限制只有指定验证者才可以恢复消息。讨论结果表明,新方案在减少计算量的前提下实现了安全的签名的指定验证者恢复消息的功能。
