摘　　要：随着Web技术的不断发展,Web服务的安全和信誉度是目前的热点研究问题,传统的SOA提供了一种新的共享模式,没有考虑到Web服务的安全和信誉问题,也不支持对Web服务信誉度的评估工作。提出了基于扩展SOA的Web服务信誉度评估模型,并重点研究了信誉度评估的算法,提出了信誉度值及综合信誉度值的计算方法,这种方法有利于服务提供者和使用者双方建立信任关系,并针对当前信任评估模型系统性能低的问题,对Web服务环境中采用的信誉评价模型进行改进,提高系统的整体性能,同时对模型中计算信誉度值及综合信誉度值的运算进行改进。通过模拟实验证明,扩展后的SOA模型考虑了服务信誉度问题,达到了预期效果。With the continuous development of Web Service, its credibility and security has become a hot spot in the research. The traditional SOA provides a new sharing model, but doesn＇ t support the credibility evaluation of WebService, It does not take into account the Web service security and credibility, and does not support Web services and credibility assessment. This paper proposes a credibility evaluation modal based on extended SOA, and focus on the algorithm of credibility evaluation. It puts forward the computation method of credibility degree and comprehensive credibility degree including both sides of service provider and service customer, so it could help build reputation relationship between them. In the end of the paper, it shows the simulation experiments, and improve the credibility of the evaluation model, improve the overall performance of the system on the Webservices environment for the low of the trust evaluation model, and improve the model to calculate the value of reputation and credibility value of an integrated computing. As the extended SOA model considers the credibility evaluation, it proves that it achieves the expected result through simulation experiments.
