摘　　要：网络中的资源评价者分为个体和团体两类。以不同评价者的信任评价为基础,提出了一种P2P网络资源选择方法。给出个体和团体对资源的片面信任计算方法,得到资源的普遍信任度的综合计算方法。提出为用户确定可取信评价者的范围,实现以可取信者为转发对象的资源查询转发。从候选资源中选择出普遍信任度最高的资源。The resource valuators in networks are divided into two types： individual valuator and group valuator. Based on the trust evaluations from different valuators, a resource selection mechanism for P2P networks is proposed. Computation method of single-faceted trust evaluation for resources from individual valuator and group valuator is presented. Universal trust can be calculated comprehensively based on single-faceted trusts. The creditable valuator boundary computation is proposed for resource requestor in order to realize trans- mitting resource queries between creditable peers. The resource selection mechanism is presented for finding out the most trustable resource from candidate resources in P2P networks.
