摘　　要：处于开放网络环境中的Web服务,时刻面临着遭遇恶意欺诈行为的风险,因此在Web服务体系中构建安全可靠的信任管理机制成为必然趋势.根据Web服务的特点,提出了一种新的信任评估模型,把对Web服务的信任度量归纳为业绩信任度和用户评价信任度两种情况.在实施信任度评估时,重点考虑服务时间、服务结果、恶意行为对信任度的影响,并按新的信任评估模型设计了Web服务的体系结构,说明了新体系结构下Web服务的应用过程.仿真结果表明提出的信任评估模型能较好地辨别Web服务应用中的恶意欺诈行为.Huge risk exists in web service because of many cheatings and malicious acts in the open environment of internet with web services. So it’s a trend to build an effective trust mechanism based on web services. According to the characteristic of web service, a new trust evaluation model is proposed. In this trust model for web services reduces to trust degree of business and trust degree of customer evaluation. During implementing trust degree evaluation, it is necessary to think about the influence of service time, service result and malicious behavior to trust degree as pivot, and it designs a new web services architecture grounded on the new trust evaluation model, and explains the application of web services under the new architecture also. Simulation experimental results show the new trust evaluation model can distinguish the cheating and malicious act in web services.
