PASSIVE: POLICY-ASSESSED SYSTEM-LEVEL SECURITY OF SENSITIVE INFORMATION PROCESSING INVIRTUALISED ENVIRONMENTS

Virtualised service platforms and cloud computing hold great promise for delivery of large applications in e-Government. However, to date, the fundamental shared-resource nature of virtualisation technologies has raised legitimate security concerns for Government and other organisations with duties to protect confidential data.

The PASSIVE project proposes an improved model of security for such virtualised systems to ensure that:

  • adequate separation of concerns (e.g. policing, judiciary) can be achieved even in large scale deployments,
  • threats from co-hosted operating systems are detected and dealt with;
  • public trust in application providers is maintained even in a hosting environment where the underlying infrastructure is highly dynamic.

To achieve these aims, the consortium proposes:

  • A policy-based Security architecture, to allow security provisions to be easily specified, and efficiently addressed.
  • Fully virtualised resource access, with fine-grained control over device access, running on an ultra-lightweight Virtual Machine Manager.
  • A lightweight, dynamic system for authentication of hosts and applications in a virtualised environment.

In so doing, PASSIVE will lower the barriers to adoption of virtualised hosting by government users, so that they may achieve the considerable gains in energy efficiency, reduced capital expenditure and flexibility offered by virtualisation.

COGEU : COgnitive radio systems for efficient sharing of TV white spaces in EUropean context

The COGEU project is a composite of technical, business, and regulatory/policy domains, with the objective of taking advantage of the TV digital switch-over (or analog switch-off) by developing cognitive radio systems that leverage the favorable propagation characteristics of the TVWS through the introduction and promotion of real-time secondary spectrum trading and the creation of new spectrum commons regime.

COGEU will also define new methodologies for TVWS equipment certification and compliance addressing coexistence with the DVB-T/H European standard. The innovation brought by COGEU is in the combination of cognitive access to TV white spaces with secondary spectrum trading mechanisms in a real demonstrator.

HURRICANE: HANDOVERS FOR UBIQUITOUS AND OPTIMAL BROADBAND CONNECTIVITY AMONGCOOPERATIVE NETWORKING ENVIRONMENTS

HURRICANE aims to provide concrete networking system answers to the question how an optimized handover operation is performed between two cooperative RATs that constitute potential business cases for both Telecom Operators and Broadcasters in the context of a FMC communications environment. The main objectives of the project are to Investigate, design, implement, validate, and propose for standardisation inter-system handover operations among radio cooperative networking environment.

UNITE: “VIRTUAL DISTRIBUTED TESTBED FOR OPTIMISATION AND COEXISTENCE OF HETEROGENEOUS SYSTEMS”

The renown beyond 3G scenario depicts a diverse wireless networking world of network-of-wireless-networks accommodating a variety of radio technologies and mobile service requirements in a seamless manner. The achievement of this vision raises significant research challenges in view of system coexistence; system scale; network robustness requirements; and evaluation tool design to provide a framework for cost-effective assessment of optimisation algorithms within a heterogeneous system environment. The UNITE platform aims to address the aforementioned research challenges by: (a) Implementing an efficient, accurate and scalable Virtual Distributed Testbed (VDT) to support cross-system, and cross-layer optimisation of heterogeneous systems in a unified manner. (b) Through the use of the virtual testbed, to investigate, design and evaluate cross-layer and cross-system interactions, between next generation radio and protocols without neglecting important real-system details.
