Wimax密码算法使用模式的探讨

目前，Wimax凭借其宽带高速的优点已经成为3G的一个标准，在无线城域网中拥有广阔的应用前景。同时，Wimax的安全问题也不客忽视，正受到越来越多人的研究，但对于密码算法使用模式的研究较少。文章重点介绍了Wimax安全子层中密码算法的三种主要使用模式（密码块链接模式、计数器模式和MAC层密码链接一计数器模式），并对它们的优缺点进行了比较分析。

Study on the Mode of Wimax Cipher Algorithm

At present, Winmax has been a 3G technical standard because of its wide bandwidth and high speed, and has bright application future in the field of WMAN. At the same time, the security of Wimax is also very important, and is now studied by more and more people. However there has less work concerning modes of cipher algorithms. In this paper, three modes of cipher algorithms in Wimax security sublayer are studied they are CBC, CTR and CCM. The advantages and disadvantages are compared and analyzed among them.
