Abstract:

Based on the 3GPP's 3G and WLAN integration program and the false AP attack in the EAP-AKA as well as the user security issues such as disclosure of private information,an EAP-TTLS-AKA authentication method is presented.This method implements the establishment of the UE authentication of the WLAN access network.The AKA authentication of 3GPP and UE is achieved in the drying tunnels.The results show that this method is an effective solution to the false AP attack,IMSI information disclosure,middle attacks and other security issues.It has high security and maintains low communication and computation overhead.
