Li Yang, Raimund K. Ege, Huiqun Yu · Software Engineering and Knowledge Engineering · 2004
Research on mediation techniques to integrate datafrom heterogeneous data sources has made comprehen-sive progress. However, mediation poses extensive securityproblems. Protecting proprietary data from unauthorizedaccess is recognized as one of the most significant barriersto the mediation systems. Neither traditional access controlmethods are adequate to model the flexible access controlrequirements, nor are they amenable to manage the evolv-able security features of mediation systems. This paper ad-dresses to enhancing mediation security by aspect-orientedapproach. The basic functionality components and secu-rity concerns are separated, independently specified, andthen systematically integrated into a unified model. Our ap-proach benefits in both decreasing design complexity of me-diation systems and increasing flexibility and dependabili tyof security enforcement.Keywords: mediation system, security, aspect-oriented,specification
