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.
