EAP-AKA(Authentication and Key Agreement)协议是3G-WLAN的认证协议之一。通过分析发现,EAP-AKA协议每次执行都需用一个AV(Authentication Vector)来产生密钥文件,这样占用了大量的通信开销和认证时间。为了解决这个问题,提出新增一个AV数组的计数管理器AM(Account Manager),从而节省AV的使用,减少通信开销,提高网络速率和QoS。
EAP-AKA ( Authentication and Key Agreement) protocol is one of the authentication protocols for 3 G-WLAN. Through the study on EAP-AKA protocol, we found that it needs an AV (Authentication Vector) to generate encryption key file for each authentication, which uses up lots of time in communication and certification. To solve this problem,we propose to add an AM ( Account Manager) for the AV array. In this way we decrease the usage of AV, cut down the communication cost, and improve the speed and QoS of the network.
