基于身份密码体制在WiMAX网络安全协议中的应用

Identity-Based Cryptography Applied in WiMAX Network Security Protocal

针对802.16-2005修正案中安全认证方面的不足,通过引入基于身份(Identity-Based)的公钥密码体制,提出了一个基于身份802.16(W iMAX)网络安全认证结构。详细描述了从初步建立系统参数,动态的共享密钥的生成,到4-way握手的相互身份认证协议的过程以及weil paring的实现。通过比较,说明了该协议在安全性方面相对于目前的无线网络安全协议的优越性。

In this paper,due to some flaws on the aspect of authentication in 802.16-2005, the author introduces the basic concept of Identity-based cryptography and presents the Identity-based framework for 802.16. The paper gives a good description of this new Identity-based framework from the process of the system setup,the session key generation to the four-round shake hands and the implement of it with the Weil Pairing. Further more, compared with several wireless network security protocals, it shows that this framework has the advantage of more convenience and flexibility than current wireless network security protocols.
