摘　　要：3G网络和WLAN的融合能够在热点地区为用户提供更高速的无线传输服务,同时在3G中提供无处不在的连接性。针对融合网中安全认证机制的研究现状,为了进一步提高UMTS/WLAN融合网中WLAN认证的安全性和高效性,提出了基于GAA-WAPI的融合网认证机制。经计算结果表明,GAA-WAPI认证机制在提高网络安全性的同时能够节省大量的通信流量。The integration of 3G mobile networks and WLAN networks can offer subscribers higher speed wireless services in hot spots and ubiquitous connectivity in 3G.Regarding the current status of authentication mechanisms over integrated network,an improved authentication mechanism based GAA-WAPI was proposed to increase the security and high efficiency of WLAN authentication over UMTS/WLAN integrated network.As the calculation results proved,this mechanism can save more traffic cost when UEs roam from one AP to another as well as provide greater security.
