| 摘 要： | 信任评价机制是P2P电子商务中一种能够识别恶意节点并确保系统正确性和可用性的有效机制。信任评价机制的准确性依赖于信任值的计算方法。目前大多数信任评价机制中没有考虑交易金额对信任值的影响，文章提出了一种基于交易标的额的信任评价模型，并给出了一种动态信任阈值设定机制，实验表明该信任模型能有效防止节点的恶意行为，可以很好地应用于P2P电子商务中。

| Abstract: | Trust evaluating mechanism is an effective mechanism which can distinguish malicious notes and insure system validity and availability in P2P e-commerce. The validity reckons on the method of calculating the trust value. At present, most of the trust evaluating mechanisms have not taken the influence of trade amount on trust value into account. A kind of trust evaluating model based on trade amount is put forward in this paper, and a mechanism of dynamic trust threshold ini-tialization is given. Experiments show that the trust model can protect from attacks of malicious notes effectively, and could be applied into e-commerce commendably. |
