Abstract: This paper proposes a trust model which combines reputation and credential. The model is based on reputation trust management, and according to the correlation of credential and reputation, the model can derive credential trust from the credential adaptively, combine the credential trust and reputation to get the overall trust value. Simulations show that this model can improve the accuracy of the trust value computation significantly, especially under circumstances where the service provider’s interaction history is very few.

Key words: trust management, reputation, credential

摘要： 提出一种融合凭证和声望的信任模型。该模型以声望式信任管理为基础，以凭证和声望值的相关性为依据，动态自适应地计算凭证的信任值，并将凭证信任与声望进行融合得出综合信任度。仿真表明，该方法可以大幅提高信任计算的精度，尤其适用于服务提供者的交互历史数据较少的环境。
