在P2P环境中，一个节点需要与未知节点进行交互以获得所提供的服务。这就需要在交互之前和之后进行信任评估。提出了Trust/sup 2/：一种新的动态的节点信任评估模型，旨在衡量节点推荐的可信度，从而过滤响应中的噪声，得到更准确、客观的信任值。在我们的模型中，在任何交互之前，信任值来自其他对等体给出的评估。在交互之后，信任值来自其他对等体的评估和请求对等体的经验。在信任评估的聚合中，请求对等体的权重变得越来越高。同时，在这个过程中，每个响应节点的推荐可信度可以逐轮测量。这导致过滤低可信度的同行和信任评估的改善。
In peer-to-peer (P2P) environments, a peer needs to interact with unknown peers for the services provided. This requires the trust evaluation prior to and posterior to interactions. This paper presents Trust/sup 2/: a novel and dynamic peer trust evaluation model, which aims to measure the credibility of peers' recommendations, and thus to filter noise in responses and obtain more accurate and objective trust values. In our model, prior to any interaction, the trust value results from the evaluations given by other peers. Posterior to interactions, the trust values results from both other peers' evaluations and the requesting peer's experience. In the aggregation of trust evaluations, the weight to the requesting peer becomes higher and higher. Meanwhile, during this process, the credibility of each responding peer's recommendation can be measured round by round. This leads to the filtering of low credibility peers and the improvement of trust evaluations.
