Abstract

Trust in software services is a key prerequisite for the success and wide adoption of Services-Oriented Computing (SOC) in an open Internet world. However, trust is poorly assessed by existing methods and technologies, especially in dynamically composed and deployed SOC systems. In this paper, we discuss current methods for assessing trust in Service-Oriented Computing and identify gaps of current platforms, in particular with regards to runtime trust assessment. To address these gaps, we propose a model of runtime trust assessment of software services and introduce a framework for realizing the model. A key characteristic of our approach is the support that it offers for customizable assessment of trust based on evidence collected during the operation of software services and its ability to combine this evidence with subjective assessments coming from service clients.
Web服务信任:走向动态评估框架
对软件服务的信任是在开放的Internet世界中成功和广泛采用面向服务的计算(SOC)的关键先决条件。然而,现有的方法和技术很难评估信任,特别是在动态组成和部署的SOC系统中。在本文中,我们讨论了面向服务计算中当前评估信任的方法,并确定了当前平台的差距,特别是在运行时信任评估方面。为了解决这些问题,我们提出了一个软件服务运行时信任评估模型,并引入了实现该模型的框架。我们的方法的一个关键特征是,它支持基于软件服务运行期间收集的证据对信任进行可定制的评估,并能够将这些证据与来自服务客户的主观评估相结合。
