Abstract

Trust management is important for agent cooperation and security in multi-agent system. Based on rough sets theory, a new trust evaluation method is proposed. The method divides attributes into necessary or unnecessary, calculates attribute weight, and then evaluates trust values by using a decision-making method. Finally, an example shows that it is efficient to evaluate trust by using the method.
