DESCRIPTION:Wireless networks (WiFi) constitute a cheap option for accessi
 ng Internet in some countries. Such networks are called 'community WiFi ne
 tworks' 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 Inter
 net connection fees. Such environment introduces strong threat of insider 
 attacks. This is one of the reasons why any security mechanisms based on s
 hared 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 deploye
 d 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.
