Advances in security architectures for data networks have traditionally been following the trail of security breaches, consequently having a lot of solutions with no coherent foundation. Integration of user data layers with security protocols has been hindered by a myriad of factors even with the realization that security must be an integral part of a network architecture. Lack of sufficient research on the subject, international trade laws, and the lack of awareness to the amount of security required by a typical user are a few to mention. The current trend is to have security at every layer of network architecture as well as in the operating system without a rigorous framework. In this presentation we discuss how a layered security architecture can be developed for future data networks and suggest some of the components of such a network. We discuss the idea of a 'Common data security network (CDSN)'. CDSN provides and implements security on the paradigm of Common channel signaling system (such as SS#7) of the PSTN. Inter-layer communications will allow layers to share security information. Some analytical results on the security architecture for Wi-Fi networks (based on the new standard IEEE 802.11i) will be presented in order to relate resource consumption by security protocols to their effectiveness.

Biographical Sketch: Dr. Aftab Ahmad earned his Doctor of Science in Communications Engineering from George Washington University (GWU) in 1992. Since then, he has worked in industry and academia. Currently, he is Associate Professor in Computer Science Department in Norfolk State University. He has authored two books: "Data Communications Principles: For Fixed and Wireless Networks and "Wireless and Mobile Data Networks". This is in addition to authoring and co-authoring a number of referenced papers in international journals and conferences. His publications are mainly in the areas of high-speed network design, resource allocation in cellular networks and QoS control in wireless networks. His current research interests include resource management and medium access control in wireless data networks, ad hoc network routing and performance modeling of communications systems.

Checks: Checks should be made out to IEEE and brought to the meeting.
