Executive Summary

Wireless networks play an important role in the everyday lives, at the workplace and at home. However, they are also relatively vulnerable: physically located off site, attackers can circumvent wireless security protocols such as WEP, WPA, and even to some extent WPA2, presenting a security risk to the entire network. To address this problem, the authors propose SecureAngle, a system designed to operate alongside existing wireless security protocols, adding defense in-depth. SecureAngle leverages multi-antenna APs to profile the directions at which a client's signal arrives, using this Angle-of-Arrival (AoA) information to construct signatures that uniquely identify each client.
