基于混沌理论的身份认证方案

基于混沌理论和一次性口令认证技术, 提出一种可以抵御常见攻击的身份认证方案. 解决了常规一次性口令认证方案不能抵御小数攻击、 明文传送迭代次数不安全以及传统Hash函数存在易于找到碰撞安全漏洞的问题, 该方案用混乱和散布性质好、 抗碰撞能力强的混沌Hash函数代替传统的Hash函数, 用混沌置乱排序算法产生的迭代次数代替网上明文传输的迭代次数, 具有较高的安全性.

Identity Authentication Scheme Based on Chaotic Theory

Based on chaotic theory combined with one time password authentication technology, an identity authentication scheme was presented which can resist attacks in common and resolve ordinary one time password unresisting small number attack and insecurity problems of transmitting plaintext iteration times and easily finding the security leak of collisions in traditional Hash function. In this scheme, traditional Hash function was substituted with chaotic Hash function of more safety about confusion and diffusion, stranger resistant collision ability, and plaintext iteration times was substituted with scramble sort algorithm generated iteration times in network, so it is more safety.
