摘要:

为解决当前P2P(Peer to Peer)网络中存在的一些安全问题,提出一种应用关系集合的P2P网络信任模型RSTM(Relationship Set Trust Model)。该模型利用关系集合,随机抽取节点,对给出应答消息的节点进行推荐,对提供服务的节点进行评估,对有不良行为者给予一定的惩罚措施。仿真实验证明,此模型可有效地剔除大部分恶意节点,阻止恶意节点集体欺骗行为,并在减小网络搜索范围的情况下,不失全面性地对节点进行评估,有效提高了P2P网络的安全性,可靠性。

关键词: P2P网络, 关系集合, 信任, 推荐, 反馈

Abstract:

For the sake of the problems that existed in P2P(Peer to Peer) networks,a trust model for P2P networks based on relationship set is proposed. RSTM(Relationship Set Trust Model)  uses the relationship set,chooses nodes randomly, makes recommendation of the nodes which gives respond information. RSTM carries evaluation through the nodes which offers services, there are some punitive measures to the malicious nodes. It has been proved through experiments. RSTM can eliminate most of the malicious nodes and prevent the collective deceive of them effectively. In addition, the proposed model evaluates the nodes roundly under the circumstance of minishing the search area.The security and reliability in P2P networks are improved effectively.

Key words: peer to peer(P2P) networks, set of relationship, trust, recommend, feedback
