Abstract

In this paper, we demonstrate how role-based access control policies may be used for secure forms of knowledge module exchange in an open, distributed environment. For that, we define an algebra that a security administrator may use for defining compositions and decompositions of shared information sources, and we describe a markup language for facilitating secure information exchange amongst heterogeneous information systems. We also describe an implementation of our approach and we give some performance measures, which offer evidence of the feasibility of our proposal
