Comparison of Surveillance Strategies to Identify Undesirable Behaviour in Multi-Agent Systems

摘要

Open, distributed systems face the challenge to maintain an appropriate operation performance even in the presence of bad behaving or malicious agents. A promising mechanism to counter the resulting negative impact of such agents is to establish technical trust. In this paper, we investigate strategies to improve the efficiency of trust mechanisms regarding the isolation of undesired participants by means of reputation and accusation techniques. We demonstrate the potential benefit of the developed techniques within simulations of a Trusted Desktop Computing Grid.
