Summary

Summary

AAA (Authentication, Authorization, Accounting) describes aframework for intelligently controlling access to networkresources, enforcing policies, and providing the informationnecessary to bill for services.

AAA and Network Security for Mobile Access is aninvaluable guide to the AAA concepts and framework, including itsprotocols Diameter and Radius. The authors give an overviewof established and emerging standards for the provision of securenetwork access for mobile users while providing the basic designconcepts and motivations.

AAA and Network Security for MobileAccess :

Covers trust, i.e., authentication and security key managementfor fixed and mobile users, and various approaches to trustestablishment. Discusses public key infrastructures and provides practicaltips on certificates management. Introduces Diameter, a state-of-the-art AAA protocol designedto meet today?s reliability, security and robustnessrequirements, and examines Diameter-Mobile IP interactions. Explains RADIUS (Remote Authentication Dial-In User Services)and its latest extensions. Details EAP (Extensible Authentication Protocol) in-depth,giving a protocol overview, and covering EAP-XXX authenticationmethods as well as use of EAP in 802 networks. Describes IP mobility protocols including IP level mobilitymanagement, its security and optimizations, and latest IETFseamless mobility protocols. Includes a chapter describing the details of Mobile IP and AAAinteraction, illustrating Diameter Mobile IP applications and theprocess used in CDMA2000. Contains a section on security and AAA issues to supportroaming, discussing a variety of options for operator co-existence,including an overview of Liberty Alliance.

This text will provide researchers in academia and industry,network security engineers, managers, developers and planners, aswell as graduate students, with an accessible explanation of thestandards fundamental to secure mobile access.


Author Notes

Madjid Nakhjiri is currently a researcher and networkarchitect with Motorola Labs. He has been involved in the wirelesscommunications industry since 1994. Over the years, Madjid hasparticipated in the development of many cellular and public safetymission-critical projects, ranging from cellular location detectionreceiver design and voice modeling simulations to the design ofarchitecture and protocols for QoS-based admission, call control,mobile VPN access and AAA procedures for emergency responsenetworks. Madjid has been active in the standardization of mobilityand security procedures in IETF, 3G and IEEE since 2000 and is acoauthor of a few IETF RFCs. Madjid has also coauthored many IEEEpapers, chaired several IEEE conference session and has many patentapplications in process.

Mahsa Nakhjiri is currently a systems engineer withMotorola Personal Devices and is involved in future cellulartechnology planning. Mahsa holds degrees in Mathematics andElectrical Engineering and has specialized in mathematical signalprocessing for antenna arrays. She has been involved in research oncellular capacity planning and modeling, design and simulation ofradio and link layer protocols and their interaction with transportprotocols in wireless environments. Mahsa has also worked withcellular operators on mobility and AAA issues from an operatorperspective.
