摘要 分析了两个基于身份的指定验证者签名方案(Zhang方案和Li-Zheng-Zhu方案),指出了两个签名方案不满足指定验证者签名的安全特性:Zhang方案不满足不可伪造性,Li-Zheng-Zhu方案中非指定验证者可以验证签名的有效性,不满足指定验证性。对两个方案进行了改进,改进后的Zhang方案满足不可伪造性,并具有与原方案相同的效率;改进后的Li-Zheng-Zhu方案不仅满足指定验证性,而且减少了一个双线性对运算,具有较高的效率。 Two identity-based designated verifier signature schemes,which were proposed by Zhang and Li-Zheng-Zhu respectively,were analyzed.It was shown that two schemes did not satisfy the security requirements of designated verifier signature.Zhang＇s scheme did not meet the unforgeability requirement;Li-Zheng-Zhu＇s scheme did not have designated verification as although the non-designated-verifier could check the validity of the signatures.Then the schemes were improved.The improved Zhang＇s scheme owns unforgeability property,and has the same efficiency as the Zhang＇s.The improved Li-Zheng-Zhu＇s scheme owns designated verification property;moreover,the improved scheme has reduced one bilinear paring and is more efficient than the Li-Zheng-Zhu＇s.
