Customizable framework for managing trusted components deployed on middleware

Due to the widespread trust threat under the open and dynamic Internet environment, the computer community has endeavored to engage in the studies of technologies for protecting and evaluating trustworthiness. This paper firstly defines trust from three aspects: trust relationship, trust property and trust entity, and build a uniform view for multiple trust properties. Secondly, according to abstract the common characteristics over varied trust properties, a model of trust management is elaborated, in which the trust entities, measurement model and trust policy are described. Thirdly, the trust management is implemented as a kind of public service on a J2EE-compliant middleware platform, i.e., the PKUAS.
