 SUBJECT AREA: Broadband Wireless Technologies, Integrated Public Access Networks

ABSTRACT

Local and wide-area wireless data networks are becoming increasingly important in providing ubiquitous seamless connectivity to end-users. Third generation wide-area networks such as CDMA-2000 and UMTS have been standardized and are gradually being deployed. In local-area wireless networks common in enterprises, home and public hot spots, the IEEE 802.11b standard is seeing explosive growth. This tutorial will provide detailed discussion of the state-of-the-art architectures, protocols, network elements, systems and open research questions in key broadband wireless technologies such as 802.11, CDMA2000, UMTS, 802.16 and emerging multi-hop all wireless mesh networks. Particular emphasis will be on the aspects of security and service integration between different technologies, as seamless inter-technology roaming and ubiquitous connectivity are perceived as the key to the success of broadband wireless.  The tutorial will include demonstrations that will use Verizon’s live 1XRTT or EV-DO network and key technologies developed in Bell Labs to illustrate various aspects of Integrated Public Wireless Networks.

Tutorial B (half day): Security in Public Wireless Networks
 

SPEAKER: Dr. Milind M. Buddhikot (milind@dnrc.bell-labs.com)
                      Lucent Bell Labs, USA

SUBJECT AREA:  Security, Broadband/Public Wireless Networks, 3G and 802.11 Networks

 ABSTRACT

Recent trends indicate that two complementary technologies, namely IEEE 802.11 Wireless LANs (1-54 Mbps, 100-300 feet range) and Third generation (3G) wide-area wireless networks (64Kbps to 2.4 Mbps, few kms range) such as CDMA2000 and UMTS will compete and co-exist to offer wireless Internet access to end-users.  One key aspect of these networks is the security architecture and associated protocols used to authenticate, encrypt and bill end user communication. The authentication phase is the first step that verifies user credentials, establishes required service class, derives session keys such as encryption and anonymization keys and commences billing before the user can access network services.

The performance and flexibility of wireless data services will be dramatically improved if users can seamlessly roam across the two kinds of networks. Given this, the Network Service Providers (NSP s) will integrate their networks using roaming agreements that allow such seamless roaming. Efficient, high performance authentication and re-authentication and derivation of session keys using a common profile shared among all NSPs will play a critical role in such integration.

This tutorial will focus on emerging stand-alone and integrated local and wide-area wireless networks such as 802.11, 3G1X, 1XEV-DO and UMTS.  It will provide in-depth knowledge of state-of-the-art security architectures, protocols, and network and client systems for user authentication, dynamic session key negotiation, encryption and accounting in these networking technologies.  It will also highlight known limitations, attacks, and security weaknesses.
