摘　　要：P2P系统中许多现有的信任评价模型在计算直接信任时,只把过去好/坏的评价数目简单的相加,这使得很难对合作伙伴的可信性做出准确的判断。为了弥补此类方法存在的缺陷,提出了一种新的基于关系强度的交互信任计算模型。通过引入在关系强度的计算过程中忽略的交易金额这个重要因素,改进了原有关系强度的计算方法。实验结果表明,P2P系统中基于关系强度的交互信任计算模型能够帮助peer选择更合适的交易伙伴。Many existing rating models for trust simply total the number of good and bad evaluations. These models, however, make it difficult to create really reliable evaluations. So interaction trust model based on strength of relationships （ITSR） is put forward. The computational method of strength of relationships is improved by introducing an important factor--transaction value--neglected in the process of trust evaluation. Experiment shows that it helps peers pick more suitable interaction partners.
