Abstract

Trust is a crucial concept in order to address scalabilityin managing security tasks such as authentication, authorizationand access control. In this paper we discuss theconcept of trust by defining a general theoretical model todescribe basic trust relationships in heterogeneous environmentscomposed of several Administrative Domains (ADs),i.e. autonomous domains for both security and administrativeissues.As a result, we introduce the design of a Trust ManagementSystem (TMS) that we plan to deploy into a middlewarearchitecture in order to provide a framework for implementingtrust relationships in Virtual Enterprises (VEs).
