摘要

构建一个基于上下文因素的多维度P2P信任模型，结合考虑时间衰减、交互重要性和交互次数度量实体交互信任，基于 Dice 相似度给出信任相似度算法，设计一种多链路反馈可信度融合算法，聚合直接交互、评价相似度和信任链传递计算实体的推荐信任，综合直接信任和推荐信任进行实体信任的评估，并提出一种新的信任更新和奖惩机制。实例分析表明，模型较好地体现了上下文因素对信任计算的影响，增强了模型在上下文因素的敏感性。

Abstract

A multi-dimensional trust model was constructed based on the context factors.The direct trust of the interac-tive entities was estimated by integrating the time-decay factor

the transaction impact factor and the participation fre-quency.The trust similarity algorithm was designed based on the Dice similarity and the feedback credibility was aggre-gated from multiple trust chains.The direct interaction

the evaluation similarity and the trust chain was integrated for calculating the recommendation trust.The peer's trust was evaluated by combing the direct trust and the recommendation trust.A new mechanisam was proposed for the trust's update

incentive or punishment according to the peer's behavior on the interaction.The practical example analysis shows that the proposed model can effectively explain the effect of the transaction contextual factors on the entity trust

and can improve the trust sensitivity to the context transaction factors.
