| Abstract: | A trust model based on social rules and the topology characteristic of unstructured P2P network is proposed in this paper. A distributed storage mechanism of evaluation information is designed. The calculating, updating and searching methods of reputation information are given. The computation complexity and communication cost of this algorithm are low. Experimental results show that the proposed trust mechanism can resist the attack of malicious peers effectively. |
