A concept of behavioral reputation system in wireless networks

Abstract

Nowadays wireless networks are becoming important in personal and public communication. Most of them are secured by 802.11i standard with strong AES cipher - WPA2. In many cases an attacker has the ability to listen to all encrypted network traffic, which may become a potential intrusion. Each client in wireless network is vulnerable to a variety of threats and attacks. Many attacks, especially in corporate networks, are realized from internal environment. Identity theft is another serious problem of wireless networks. We present a concept of reputation system based on user behavior. Our goal is to precisely identify every entity in wireless network, and then determine malicious behavior of these entities.
