第3代合作伙伴计划(3GPP)制定的UMTS与WLAN互联方案可以实现UMTS与WLAN的优势互补,既能提供3 G网络的全球覆盖、基础设施、漫游和计费等,又能实现WLAN的低成本和高数据率。通过对UMTS与WLAN安全机制的分析,详细说明了互联网络安全机制EAP-AKA的工作流程,在WLAN用户侧使用IEEE802.1x协议进行认证存在着假冒AP等安全隐患,文章提出采用双向认证的方式来健全互联网络的安全机制,使互联网络可以提供更加完善、安全的服务。
The 3rd generation partnership project (3GPP) UMTS and WLAN interconnection scheme can realize the complementary advantages of UMTS and WLAN. It not only provides global coverage, infrastructure, roaming and charging of 3G networks, but also achieves low WLAN Cost and high data rate. Through the analysis of UMTS and WLAN security mechanisms, the work flow of EAP-AKA, an Internet security mechanism, is described in detail. There are security risks such as counterfeit APs when authenticating WLAN users using the IEEE802.1x protocol. The paper proposes a bidirectional authentication approach To improve the security mechanism of the Internet so that the Internet can provide a more complete and safe service.
