There have been a number of proposals for trust and reputation-based systems. Some have been implemented, <br> some have been analysed only by simulation.

We investigate <br> the effectiveness of our architecture by simulating distributed attacks on a network that uses <br> trust/reputation as a basis for access control decisions. <br>
