| 摘 要： | 针对P2P网络内部的安全问题，提出了一种P2P网络基于直接交易信任和推荐信任的模型，运用了直接交易信息参数、推荐信息的评价可信度和动态平衡权值参数，较简单准确地描述了节点的综合信任值，在进行交易前与目标节点建立信任关系，能有效抑制恶意节点对网络中其他节点的恶意交易行为和评价欺骗，提高网络交易的安全性。

| Abstract: | According to the inner security issue of Peer-to-Peer (P2P) networks, a trust model based on direct transaction and recommendation in P2P network was proposed. Parameters of direct transaction information, rating confidence degree of recommendation information and dynamic balance weight were applied in the model. The model described peer’s integration trust simply and accurately, and established trust relationship with target peer before transaction, which can restrain malicious peer to do malice behavior and rating cheat to other peers in the network, and improve the security of network trade. |
