WiMAX加密方案研究

Research on the Encryption Scheme of WiMAX

WiMAX安全要实现两大目标:一是为整个无线网络提供机密性保护;二是提供网络接入控制功能。机密性保护是通过对用户台与基站之间的连接进行加密来实现的。基站通过对整个网络的业务流进行加密,来防止未授权接入。本文首先给出了WiMAX网络安全体系架构,然后对RSA、DES-CBC、AES-CCM算法的工作原理和加密过程进行了详细的介绍。

WiMAX security has two goals, one is to provide privacy across the wireless network and the other is to provide access control to the network. Privacy is accomplished by encrypting connections between the subscriber station and the base station. The base station protects against unauthorized access by enforcing encryption of service flows across the network. This paper proposes the security architecture of WiMAX, analyzes the principium, encryption process of RSA, DES-CBC and AES-CCM.
