针对当前认证方案中普遍存在的认证效率较低和认证过程较复杂等问题,提出一种基于ELGamal数字签名的双向认证方案,引入密钥分配中心作为第三方,承担公钥的分发并与认证双方进行通信.分析结果表明,该方案在离散对数问题的基础上提高了难度,在计算量方面优于其他双向认证方案,可广泛用于分布式环境下的身份识别和数字签名.

Aiming at the problems of low authentication efficiency and its complex process,a double-way authentication scheme of ELGamal digital signature is proposed.The Key Distribution Center(KDC) is introduced as the third aspect,which distributes the public keys and communicates with both sides.Analysis results show this scheme improves the complexity than discrete logarithm and the computing efficiency is better than others.The scheme may have some comprehensive application in identification and digital signature.
