结合移动网络技术的发展,IEEE802.16标准的修订,移动WiMAX网络技术的充分利用,文章对移动WiMAX网络存在的未认证消息、未加密管理通信、多“与”广播服务中的共享密钥等三个方面安全缺陷引发攻击者对网络有效攻击的分析,提出对部分敏感的未认证消息加密、通过对管理通信进行加密、多“与”广播服务密钥更新算法的改进方案,使移动WiMAX的安全性可以得到很大提升。
Combined with the development of mobile network technology, the revision of IEEE802.16 standard and the full utilization of mobile WiMAX network technology, the article discusses the existing problems of mobile WiMAX network, such as unauthenticated messages, unencrypted management communications, shared secrets in multi-service broadcast service Key and other three aspects of security flaws caused by the attacker to attack the network effectively, put forward some sensitive encryption of unauthenticated messages, through the management of communication encryption, more “and ” broadcast service key update algorithm improvements, So that mobile WiMAX security can be greatly improved.
