【摘要】 针对Internet环境下广泛的信任危机,人们着力于研究可信性支撑和度量技术.传统模型和机制很少从信任本身看问题,并且大多只涉及可信的单个方面,对于有多种可信特性需求的系统来说,很难提供一致的管理.本文以Internet环境下的软件服务为研究实体,从信任角度出发,致力于为软件服务的可信性管理建立一致视图.首先基于中间件建立了一个信任管理模型,然后基于对可信特性的共性提炼,构建了一个可定制、扩展性良好的信任管理框架,并以可扩展为目标建立了一个可行的可信性度量模型.最后基于构件运行支撑平台PKUAS进行了设计和实现,并与相关工作进行了比较.更多还原

【Abstract】 <Abstrcat>Being confronted with the trust crisis under the Internet environment,people have endeavored to develop technologies for supporting and measuring trust.Basically,traditional models and mechanisms seldom studied trust from the perspective of the trust itself and most of them can only deal with trust on a single aspect.Those traditional approaches cannot manage or support trust in consistent ways when systems are required to be in possession of multiple trust properties.Regarding software services in the Internet environment as the investigating entities,this paper is devoted to build uniform view for multiple trust properties.Firstly,a trust management model based on middleware is built.Secondly,based on the model,a trust management framework is built,which is customizable and extendable.Thirdly,by analyzing various trust properties deeply,a viable trust-measuring model is setup.At last,the framework is implemented on the top of a middleware platform,i.e.,the PKUAS.This paper also compares our research with the related work.更多还原
