Authorization and trust enhanced security for distributed applications

Abstract

This paper addresses the issues of authorization and trust in a federated distributed environment. We describe some of design principles involved in the development of authorization service for practical large scale distributed systems. We present the design of web services authorization architecture and discuss its implementation within the NET framework. Then we discuss the notion of trusted computing and presented our approach and architecture to enhancing the distributed authorization service using trusted platforms technologies. © Springer-Verlag Berlin Heidelberg 2005.
