IEEE802.16e标准安全机制的改进

Improved security mechanism for IEEE802.16e standard

指出了IEEE802.16e安全机制中所存在的严重漏洞。针对无线移动设备存在存储容量有限、处理速度慢、带宽低等问题,利用无线公钥设施中的证书标识符URL和椭圆曲线加密算法对IEEE802.16e中的密钥管理协议(PKM)进行了改进。仿真结果表明改进后的安全机制更适合于无线网络环境。

This paper points out some serious leaks in the security mechanism of IEEESO2.16e.In the face of limited resources of wireless mobile devices such as low processing,bandwidth and storage capabilities,this paper utilizes the certificate URL in the WPKI and ECC eneryption algorithm to improve the Key Management Protocol（PKM） of IEEE802.16e.The simulator result shows that the improved security mechanism is more suitable for the wireless network.
