Resistance of Trust Management Systems against Malicious Collectives

Abstrakt

Malicious peers in Peer-to-peer networks can develop sophisticated strategies to bypass existing security mechanisms. The effectiveness of contemporary trust management systems is usually tested only against simple malicious strategies.

In this paper, we propose a simulation framework for evaluation of resistance of trust management systems against different malicious strategies. We present results of five TMS that represent main contemporary approaches; the results indicate that most of the traditional trust managements are vulnerable to sophisticated malicious strategies.
