摘要
Abstract
With the rapid development of Peer-to-Peer(P2P) network in recent years, there exist a lot of unsafe service problems. Aiming at this problem, a trust mechanism based on cloud model is proposed. A kind of cloud model algorithm based on node’s trust vector is proposed. For several nodes which matching the query condition, it uses gray theory to predict trust vector of current cycle based on its previous trust vectors, and creates cloud model for several current trust vectors, selects the trustworthy node to service the source query node depending on the decision algorithm of trust-cloud and the similarity measure algorithm of trust-cloud. Simulation experimental result shows that when selecting the target service nodes, this mechanism can not only depend on node’s mean trust-value, but also take trust-value discreteness into considering. So it can select the most trust node from different angles, improve the quality of network service, and achieve the purpose of enhancing network security.关键词
