摘要 以改善P2P网络的安全性能为目标,介绍了基于关键节点的混合式P2P结构和基于信誉的信任机制,提出了一种基于该信任机制的混合式P2P模型,描述了该模型的工作机制。利用该模型可以在两个对等实体之间建立高效、可靠的信任关系,有效防止恶意攻击,提高P2P网络的效率和安全。 To improve the security performance of P2P networks, the hybrid P2P structure based on sticking point and the reputation-based trust mechanism was introduced, and a hybrid P2P model based on the reputation-based trust mechanism was proposed. Meanwhile, the workflow of the model was described. The model can effectively build up a high efficient and reliable trust relationship between peers, prevent malicious attack and enhance security and efficiency of the P2P networks.
