AntRep: A swarm intelligence based trust model in P2P networks

Reputation-based trust management is considered as a promising way to solve the problem of security issue in P2P networks. However, representing and obtaining reputation evidence for building trust relationships is not an easy job. We tackle this problem by employing a scheme for the evaluation and distribution of reputation evidence, which is based on the swarm intelligence paradigm. Our simulations show that it performs very well in P2P environment. We hope that these methods will help move the reputation based trust management closer to fulfill its promise in P2P networks, and provide a paradigm of trusted computing inspired by biology.
