| 摘 要： | 首先依据新实体能力属性给出了初始信任度计算算法，然后根据实体的直接交互满意度与其他信任实体的推荐信息，设计了直接信任度和推荐信任度计算算法。综合三种信任度，提出了信任度计算模型。该模型为网络实体间信任关系的建立和信任行为的决策提供了有力依据，从而减少实体交互风险，提高网络运行稳定性。

| Abstract: | An algorithm to compute an initial trust value for the new entities based on its capability was presented, and then the computation algorithms of direct trustworthiness based on the degree of interaction satisfaction were designed. The recommendation trustworthiness based on the recommendation opinions came from trusted entities. Finally, the integrated trustworthiness computation model was given. Based on this model, the trust relationships can be built among entities in P2P network service environment and the decision of trust can be made based on the trustworthiness, and the risk can be reduced and the stability of network can be promoted. |

| Keywords: | P2P network trust trustworthiness capabilities attribute degree of satisfaction |
