3G与WLAN融合中认证协议的分析与改进

Analysis and Improvement of Authentication Protocol in 3G and WLAN Integration

通过分析3G和WLAN融合方案中在安全认证方面的不足,指出认证过程中WLAN的AP不能得到验证的问题,提出了"认证平衡"接入方案,并分析证明了该方案能使通信的各方都能够得到有效的认证,有效地消除了融合过程中AP不能得到认证的弊端.

This paper analyses the authentication deficiency of the program in the integration 3G with WLAN,and points out the problem that the AP in WLAN can＇ t be authenticated in the authentication process.The author put forward＂Balance authentication＂program for access.And the result demonstrates that this program can authenticate every entity in communication,and then eliminate the defect mentioned above.
