Abstracts

Elin Sundby Boysen, talk "Generic solutions to include new carrier systems in UMA"

A mobile subscriber with a UMA (Unlicensed Mobile Access) enabled, dual-mode handset may access GSM and GPRS services over unlicensed spectrum technologies like Bluetooth and 802.11 (WiFi) as well as the standard cellular network. The subscriber may roam and handover between cellular networks and public and private wireless networks.

In rescue operations or for military purposes a handset that could use whichever carrier system available would be useful. By making the handsets available to roam between GSM cellular network and WiFi or Bluetooth fixed wireless network, but also between other future carrier systems like WiMAX or Tetra, the handsets will have a better chance at finding coverage and gaining access to a network even though its preferred network is either congested, blocked or simply not covering the area in question.

Services and operational capabilities that must be considered when allowing 3GPP - WLAN interworking are amongst others: common billing and customer care, access control, authentication and authorization, seamless service continuity, roaming and handover.

Ketil Lund, talk "QoS-aware middleware in network-based defense"

The principles of Network-Based Defense (NBD) highlight the need for seamless and secure information exchange. To achieve this, Service Oriented Architecture (SOA) has been recognized as one of the key enablers. At the same time Web Services has become the de-facto technology for implementing SOA. However, NBF represents a considerable challenge for SOA, with factors such as highly mobile units, low and variable data throughput, and unreliable links. Since Web Services technology primarily is intended for high-bandwidth networks, it is not possible to put this technology to use in an NBD-context without adapting it first. In this presentation we will provide a short introduction to NBD and the most relevant SOA protocols and technologies for such a context, and present what we consider to be the most important research challenges within this area.

Eli Winjum, talk "Securing mobile wireless ad hoc networks"

Mobile wireless ad hoc networks are vulnerable to security attacks. The wireless channel is accessible to all. Dynamic network topology makes detection of irregularities difficult. The absence of infrastructure and authorization facilities encumbers the establishing of a line of defense. Due to scarce network resources, traditional security solutions are often unfeasible. Distributed, redundant and lightweight algorithms and protocols are desired. Research areas include trust, authentication, encryption, key management and intrusion detection. Network security is a multilayer issue. Also, security services should interoperate with corresponding services in fixed networks and support multiple levels of trust as well as multiple security domains.
