Frictionless Authentication Systems: Emerging Trends, Research Challenges and Opportunities
Authentication and authorization are critical security layers to protect a
wide range of online systems, services and content. However, the increased
prevalence of wearable and mobile devices, the expectations of a frictionless
experience and the diverse user environments will challenge the way users are
authenticated. Consumers demand secure and privacy-aware access from any
device, whenever and wherever they are, without any obstacles. This paper
reviews emerging trends and challenges with frictionless authentication systems
and identifies opportunities for further research related to the enrollment of
users, the usability of authentication schemes, as well as security and privacy
trade-offs of mobile and wearable continuous authentication systems.Comment: published at the 11th International Conference on Emerging Security

Landscape Study in Wireless and Mobile Learning in the post-16 sector
In the post-16 sector (further and higher education, and adult and community learning) there is a need to understand how wireless and mobile technologies can contribute to improving the student experience of learning, and help institutions fulfil their missions in an age of incomparably fast technological change. In the context of this interest and growing need, a Landscape Study project was commissioned by JISC through the Innovation strand of the JISC e-Learning Programme in 2004-5. Our project aims were to take a birds-eye view of developments and practice in the UK and internationally, and to communicate our findings to a broad and varied audience. The Summary report is accompanied by 3 associated reports on 'Current Uses', 'Potential Uses' and 'Strategic Aspects'. (The four reports are available in one single document here.
5GNOW: Challenging the LTE Design Paradigms of Orthogonality and Synchronicity
LTE and LTE-Advanced have been optimized to deliver high bandwidth pipes to
wireless users. The transport mechanisms have been tailored to maximize single
cell performance by enforcing strict synchronism and orthogonality within a
single cell and within a single contiguous frequency band. Various emerging
trends reveal major shortcomings of those design criteria: 1) The fraction of
machine-type-communications (MTC) is growing fast. Transmissions of this kind
are suffering from the bulky procedures necessary to ensure strict synchronism.
2) Collaborative schemes have been introduced to boost capacity and coverage
(CoMP), and wireless networks are becoming more and more heterogeneous
following the non-uniform distribution of users. Tremendous efforts must be
spent to collect the gains and to manage such systems under the premise of
strict synchronism and orthogonality. 3) The advent of the Digital Agenda and
the introduction of carrier aggregation are forcing the transmission systems to
deal with fragmented spectrum. 5GNOW is an European research project supported
by the European Commission within FP7 ICT Call 8. It will question the design
targets of LTE and LTE-Advanced having these shortcomings in mind and the
obedience to strict synchronism and orthogonality will be challenged. It will
develop new PHY and MAC layer concepts being better suited to meet the upcoming
needs with respect to service variety and heterogeneous transmission setups.
Wireless transmission networks following the outcomes of 5GNOW will be better
suited to meet the manifoldness of services, device classes and transmission
setups present in envisioned future scenarios like smart cities. The
integration of systems relying heavily on MTC into the communication network
will be eased. The per-user experience will be more uniform and satisfying. To
ensure this 5GNOW will contribute to upcoming 5G standardization.Comment: Submitted to Workshop on Mobile and Wireless Communication Systems

An Architectural Framework for Collaboration of Heterogeneous Communication Devices Using WAP and Mobile Device Augmented(MDA)Gateway Integration
Within the last couple of years, the challenge of displaying collaborative multimedia
information has become very important with the large diversity of communication devices
such as Personal Computers, laptops, notebooks and handheld devices. The shared data
and information may be presented with different views depending on the communication
device used by a particular collaborator. The use of various web tools (HTML, WML etc)
offers some solutions to the problem but if the target application requires more complex
features such as rich multimedia data than is manageable using HTML or WML format,
something else need to be done. In this paper, we propose a framework that integrates WAP
and MDA Gateway to support collaboration among virtual teams and nomadic workers
using heterogeneous communication devices. We then discuss an approach for augmenting
mobile device small screen capabilities with surrounding large screen display device
