Authentication, Authorisation, and Access Control in Mobile Systems

Abstract

Converging networks and mobility raise new challenges towards the existing authentication, authorisation, and accounting (AAA) systems. Focus of the research is towards integrated solutions for seamless service access of mobile users. Interworking issues between mobile and wireless networks are the basis for detailed research on handover delay, multi-device roaming, mobile networks, security, ease-of-use, and anonymity of the user. This chapter provides an overview over the state of the art in authentication for mobile systems and suggests extending AAA mechanisms to home and community networks, taking into account security and privacy of the users.
