摘要
针对无线网络安全威胁,提出了一种基于混沌算法的无线安全认证方案,利用混沌对初始条件的依赖性可以生成混沌序列,以此作为无线用户的身份,这种身份具有惟一性和不可伪造性,并且是可以动态变化的。同时还给出了IEEE802.11无线局域网环境中基于混沌理论的动态认证方案和过程。研究结果表明,该方案具有良好的加密效果,运算量小,抗攻击强,有较高的安全性。
Considering the menace of wireless network security, this paper proposed a wireless security authentication scheme based on Chaos algorithm, which can generate Chaos array based on Chaos. Dependence on the initial condition. According to this, wireless security authentication scheme can act as a wireless user, which make it unique, unforgeable, and dynamically change. In addition, the paper provided dynamic authentication scheme and process based on Chaos theory in IEEE 802.11 wireless LAN environment. The research results showed that the scheme has good encryption ability, little operation, strong anti-attack ability, and the high security.
