摘要: 提出一种安全结构化对等网络的节点信誉管理机制。使用全局储存方式保存信誉度信息,将文件信誉与节点信誉相结合,避免恶意节点通过修改标识符伪装友好节点的行为。对文件共享系统中的基本操作过程进行分析。在各种节点行为下进行模拟实验,结果证明了该信誉管理机制的有效性。

Abstract: This paper proposes a node reputation management mechanism of secure structured P2P networks. It uses global storage to save reputation information. File reputation and peer reputation together are used for preventing untrustworthy files from spreading even in case of allowing malicious peers to change their identities. The basic operations in file sharing systems are analyzed. Simulation experiments under various kinds of node behaviour proves the validity of the secure reputation mechanisms.

Key words: structured P2P network, reputation mechanism, Distributed Hash Table(DHT), resource sharing
