虚拟计算环境下信任管理研究

ON TRUST MANAGEMENT IN IVCE

可信保证体系是虚拟计算环境的基础组件。虚拟计算环境下信任管理具有不确定性和动态性特点,因此,虚拟计算环境下的可信保证体系应具备主观性、基于证据以及上下文相关性的特性。针对虚拟计算环境下虚拟共同体的服务选取以及自主元素的可信度计算的安全问题,提出了基于贝叶斯分析的信任模型。

Trustworthiness assurance system is an elementary component in internet-based virtual computing environment （iVCE）. The uncertainty and dynamic characteristics of trust management in iVCE necessitate the requirement for the trustworthiness assurance system to be subjective,historical evidence based and context dependent. This paper presents a Bayesian analysis-based trust model ,which is aimed at the service selection of appropriate virtual commonwealth in iVCE and the security in trustworthiness computation of the autonomic agents.
