【摘要】 论文指出了文献[1]中的零知识证明协议在公钥参数选取上的安全漏洞,并从求解离散对数的角度进行了分析证明。然后吸取了DSA数字签名算法中安全密钥选取高效简单的优点,提出了一种比Schnorr身份识别方案快1／3的简单、安全、高效的零知识证明身份识别方案。更多还原

【Abstract】 We point out secure weakness of the Zero-knowledge proof scheme proposed by Sultan Almuhammadi and Clifford Neuman[1] in parameter selecting of public key, and analyze it from calculation of discrete logarithm. Then we propose a new Zero-knowledge proof identification scheme by combining with the effectual cipher key selection method in DSA. The analysis shows that the new scheme is secure, efficient and 1/3 faster than Schnorr’s.更多还原
