摘要:

P2P网络的匿名性和动态性带来了许多安全问题,传统的信任管理模型并不能很好的适应对等网络环境。提出了一种基于推荐的P2P网络信任模型,将节点提供服务和推荐的能力进行区分,用信誉值表示节点的推荐能力,根据节点的直接信任值、其它节点的推荐信任值和相应的惩罚值来计算节点的信任度,节点依据信任度选择交易对象。仿真实验表明,基于推荐的信任模型能有效的评估节点的信任度,在交易成功率上要优于传统的信任管理模型。

Abstract:

The anonymity and dynamics of the P2P (peer to peer) network bring many security problem, The traditional trust manage model can not satisfy the P2P environment commendably. This paper proposes a recommendation-based trust model in P2P network, the model distinguishes the ability of peer between providing service and offering recommend, uses reputation value to express the ability of offering recommend, the peer’s trust value is assessed according to direct trust value, other peer’s recommendation trust value and the corresponding penalty value, then the peer decide which to choose. The simulation experiment results show that the recommendation-based trust model is able to assess the peer’s trust value more effectively, surpass the traditional trust management model in the transaction success ratio.

Key words: P2P, trust, reputation, trust model, recommendation-based trust model
