Wireless, security, and network


The man-in-the-middle (MiM) attack exploited the vulnerability existed in WLANs based on 802.11 standards to attack the wireless network. Despite the enhancements provided by WEP for WLANs, the demands for a further secured environment still a high priority issues in wireless network. This basic deficiency leads to several potential security attacks on WLAN which is exploited by the MiM attack. Using a Mutual Authentication between the AP and MSs [18] solve the problem of the man-in-the-middle attack which is important in WLANs. The Mutual Authentication between the Wireless Access Point (AP) and Wireless MS enables each side to authenticate the other party before establishing a communication channel. This is done with the corporation of Wireless server that stores all public key of the MSs which can be used by the AP to authenticate the mobile terminals during connection setup. Hence, the MiM attack can be detected by the mobile terminal and its effect will be illuminated. In this paper, the mutual authentication concept has been extended to cover multiple APs belong to the same network. In addition to the mutual authentication, the authentication information of MS has been advertised to multiple APs for fast authentication during roaming.
