Abstract
Wireless networks (WiFi) constitute a cheap option for accessing Internet in some countries. Such networks are called ‘community WiFi networks’ as a group of people must establish a form of cooperation allowing them to agree on the terms of usage and to collect money for paying Internet connection fees. Such environment introduces strong threat of insider attacks. This is one of the reasons why any security mechanisms based on shared key are hard to effectively deploy. The talk will introduce approach based on reputation systems – analysing properties of network clients in relation to WiFi access points. We have implemented the system and deployed it in a community network with some 200 members in a very basic form so we give some results of the deployment. We will also overview our current directions for improvements of the system.
