中文摘要：

文章研究了对等网网络社区中信任机制的工作原理：社区普通节点提出查询请求,由社区管理节点验证请求节点的身份是否合法,接着向合法普通节点推荐可信任节点来满足其查询请求,知识共享结束后对双方信任值进行存储更新处理。具体描述了相关模块的功能并给出了信任机制的工作流程图,最后通过实例进行验证并对未来的研究进行展望。

英文摘要：

This paper studies the working principle of the trust mechanism in the peer-to-peer network community.The ordinary node in the community puts forward the request for query.The management node in the community verifies whether the identity of the request node is legal or not.Then the credible node is recommended to the legal ordinary node to meet the request for query.After the completion of knowledge sharing,the trust value of both sides is stored and updated.The paper describes the function of the related module in detail,and gives the flow chart of the trust mechanism.Finally,an example is given to verify the process,and the future research is predicted.
