【摘要】 提出了一种基于ElGamal体制的零知识身份鉴别方案,结合零知识证明的思想及智能卡技术,既保证了身份证明的有效性,又保护了用户的秘密信息。该方案在离散对数问题和随机预言模型假设下是安全的。更多还原

【Abstract】 A zero-knowledge proof scheme of identity authentication based on ElGamal digital signature is proposed,across zero-knowledge proof and smart card technology,we authenticate the user’s identity efficiently and secretly.The scheme is secure under the assumption of the intractability of logarithm problems and the random oracle model.更多还原
