LTE Security

Abstract

LTE is a new radio technology that could be seen as the next generation after GSM and WCDMA. 3GPP has finalized specification work for the first release of LTE in end of 2008 and first products are also expected fairly soon. LTE is accompanied by a new network architecture, called SAE in 3GPP, which allows also other radio technologies (including technologies not specified by 3GPP) to be connected to the one and same core network. This new setting requires many enhancements to 3G security features, and completely novel security techniques are also introduced with LTE. More specifically, the new architecture is flat (compared to GSM or 3G network architectures) which restricts the possibilities of placing security functions on the network side. As a consequence, some important security functions, e.g. encryption of user data, are terminated in the LTE base station site. This kind of very distributed approach to security requires many enhancements to the 3G security model. The new security features would be covered in the talk, with explanations of the background and the reasoning behind the design decisions. Also, comparison to GSM and 3G security architectures is given, and altogether, light is shed on the evolution of security that has happened together with the evolution of the radio and network technologies.

State of the Art of Relaying Technologies in Modern Wireless Communication Systems

Abstract

The very high data rate demands for the wireless communication systems create a need for more fundamental enhancements, other than just increasing the transmission bandwidth or introducing higher order modulation and the coding schemes. Along with technologies, such as MIMO and cooperative multi-point transmission, relaying is foreseen as a quite promising solution. At the moment, there are two major wireless technologies where multi-hop relays gained a significant interest from vendors and operators: 3GPP LTE-A and the IEEE 802.16j extensions of the baseline IEEE 802.16 system. In this talk an overview of the relaying standardization activities is given with functional features taken by the industry. Along with the standardization landscape, we will highlight related base station and relay station design and deployment issues that create a strong motivation for the relay deployment. In addition, we will present an overview of competing solutions for the in-door coverage, such as femto cells.

The future is mobile (ad hoc) networking?

Abstract [the talk is organized and sponsored by the SASN workshop]

In the last decade, mobile ad hoc networking has been suggested as a technology for realizing the ubiquitous computing vision. However, after more than ten years of research in this field, this promising technology has not yet entered the mass market. One of the main reasons for this is the lack of a pragmatic approach to the design of infrastructure-less multi-hop ad hoc networks. However, this paradigm was successfully applied in several classes of networks that are penetrating the mass market. In this tutorial, we discuss as examples mesh, opportunistic, vehicular, and sensor networks, where the multi-hop ad hoc paradigm is applied in a pragmatic way to extend the Internet and/or to support well-defined application requirements. In particular, we highlight how the proliferation of mobile devices is driving our reality toward a pervasive world, where all these classes of networks have concrete and effective use, as for example: location-based or social-based applications. We describe some examples of current and future application that can be realized only thanks to those classes of networks that exploit the mobile ad hoc networking paradigm.

Communicating with Understanding. Cognition, Language, and Emotions

Abstract

Today communications are intended for human understanding. Computers transfer contents of images, texts, and speech into communicable codes, but do not understand these contents. Future communication systems will understand the meanings of what is communicated, will understand user needs, and will be a part of integrated human-computer systems, in which computers and human users will learn from each other. Cognitive research indicates that emotional mechanisms are fundamental to cognition and to interaction between cognition and language. Creating cognitive algorithms for understanding text, language, and surrounding world has met difficulties since the 1950s. The talk briefly reviews past mathematical difficulties of artificial intelligence and new mathematical techniques of dynamic logic (DL), which overcome these difficulties. DL evolve fuzzy concepts and contents into crisp ones. Computational and neural mechanisms of concepts, emotions, instincts are described; they are inseparable from perception and cognition. Engineering applications illustrate orders of magnitude improvement in recognition, data mining, fusion, financial predictions. DL is extended to language, to mechanisms of joint operations of language and cognition, and to understanding complex situations. The brain imaging experiments have confirmed mechanisms of DL and language-cognition interactions in the human brain. Development of algorithms involving emotional, conceptual, and language mechanisms is still at an incipient stage. The talk discusses the current state of art and future research directions. These include developing future adaptive self-improving web tools capable of learning and understanding contents, web search engines with human level understanding, relating engineering algorithms and human instinctual mechanisms, emotional intelligence and emotional contents of languages, understanding differences among languages and cultures in their emotional contents, and developing approaches to improve inter-cultural communication.

Resilience, Survivability, and Heterogeneity in the Postmodern Internet

Abstract

Society increasingly relies on computer networks in general, and the Internet in particular. Consumers rely on networks for access to information and services, personal finance, and for communication with others. The Internet has become indispensable to the routine operation of businesses and to the global economy. The military depends on network centric operations and warfare. Governments depend on networks for their daily operation, service delivery, and response to natural disaster and terrorist attacks. Furthermore, the Internet is being used in ways not anticipated by its designers and evolution of the protocols, in particular: TCP, IP, BGP, DNS, and HTTP. Emerging application paradigms and mashups coupled with usage scenarios that are increasingly disconnected and mobile challenge the current architecture. This has been recognised by research and development initiatives including NSF FIND (Future Internet Design), GENI (Global Environments for Network Innovation), and EU FIRE (Future Internet Research and Experimentation). This presentation will focus on two key aspects of the future Internet: resilience and heterogeneity.

Resilience: The consequences to disruption of the Internet are increasingly severe, and threaten the lives of individuals, the financial health of business, and the economic stability and security of nations and the world. With the increasing importance of the Internet, so follows it's attractiveness as a target from bad guys: recreational and professional crackers, terrorists, and from information warfare. The EU FIRE ResumeNet project is exploring resilience and survivability as critical properties of the future Internet architecture.

Heterogeneity: New applications and usage scenarios stress the Internet architecture that has evolved assuming a stable wired infrastructure. While the current hourglass waist provided by IP, DNS, and BGP has served the Internet well, the demand for heterogeneity stresses the least-common-denominator of the waist. The NSF FIND Postmodern Internet project (PoMo) is exploring heterogeneity as a first-class citizen in the Postmodern Internet, in which a new internetworking protocol serves as the glue for heterogeneous realms with explicit support for trust and policy boundaries.

The Great Plains Environment for Network Innovation (GpENI) is constructing part of the GENI infrastructure, which will in part be used as a platform to test and evaluate ResumeNet and PoMo architecture. Additionally, research in two domain-specific realms will be described.

Highly Dynamic Airborne Networking

Highly dynamic mobile wireless networks present unique challenges to end-to-end communication, particularly caused by the time varying connectivity of high-velocity nodes combined with the unreliability of the wireless communication channel. Addressing these challenges requires the design of new protocols and mechanisms specific to this environment. Our research explores the tradeoffs in the location of functionality such as error control and location management for high-velocity multihop airborne-sensor networks and presents cross-layer optimizations between the MAC, link, network, and transport layers to enable a domain specific network architecture, which provides high reliability for telemetry applications. We have designed new transport, network, and routing protocols for this environment: TCP-friendly AeroTP, IP-compatible AeroNP, and AeroRP, which show significant performance improvement over the traditional TCP/IP/MANET protocol stack. Weather Disruption-Tolerant Millimeter-Wave Mesh Networking Millimeter-wave networks have the potential to supplement fiber in providing high-speed Internet access, as well as backhaul for emerging mobile 3G and 4G services. However, due to the high frequency of operation (70-90 GHz), such networks are highly susceptible to attenuation from rain. A resilient mesh topology with cross-layering between the physical and network layer has the potential to self-optimise under the presence of unstable links. Our research investigates mechanisms to overcome the disruptive effects of rain storms on network connectivity and service reliability. We propose two novel domain-specific predictive routing algorithms: P-WARP that uses real-time radar data to dynamically reroute traffic in advance of link failures, as well as a modified link-state algorithm XL-OSPF that uses cross-layering to instantaneously react to link failures. Simulations evaluate the effectiveness of the proposed algorithms based on data from real storms in the Midwest US.
