Secure wireless gateway

Wireless LANs (WLAN), using the IEEE 802.11b standard, have been shown to be inherently insecure. Given the widespread use of this type of WLAN for public and corporate access, it is important to have an "idiot proof" method for securing WLAN from hacking, sniffing, and unauthorized access.In this paper, we present a simple solution using IPSEC that provides an inexpensive, easy to implement, wireless gateway, and an access point that is secure. The client configuration involves no additional software, and the simple steps needed to configure a client are provided using a captive portal. Thus, the gateway is designed to minimize the intrusion to the end user, will only be slightly different from using a standard wireless network, and will require no additional software or hardware.
