O-band QKD link over a multiple ONT loaded carrier-grade GPON for FTTH applications

We have successfully integrated an O-band commercial Quantum-Key-Distribution (QKD) system over a lit GPON testbed that replicates a carrier-grade Fiber-to-the-Home (FTTH) optical access network with multiple ONTs to emulate real-life FTTH operational deployments.Comment: 3 page

Security for smart mobile networks: The NEMESYS approach

The growing popularity of smart mobile devices such as smartphones and tablets has made them an attractive target for cyber-criminals, resulting in a rapidly growing and evolving mobile threat as attackers experiment with new business models by targeting mobile users. With the emergence of the first large-scale mobile botnets, the core network has also become vulnerable to distributed denial-of-service attacks such as the signaling attack. Furthermore, complementary access methods such as Wi-Fi and femtocells introduce additional vulnerabilities for the mobile users as well as the core network. In this paper, we present the NEMESYS approach to smart mobile network security, to develop novel security technologies for seamless service provisioning in the smart mobile ecosystem, and to improve mobile network security through a better understanding of the threat landscape

Mobility modeling in third-generation mobile telecommunications systems

Abstract: In mobile communications, mobility modeling is involved in several aspects related to signaling and traffic load analysis. In third generation systems, the influence of mobility on the network performance (e.g., handover rate) will be strengthened, mainly due to the huge number of mobile users in conjunction with the small cell size. In particular, the accuracy of mobility models becomes essential for the evaluation of system design alternatives and network implementation cost issues. In this paper, we propose three basic types of mobility models, which are appropriate for the analysis of the full range of mobile communications ' design issues. The models provide different levels of detail regarding the user mobility behavior. In particular: (a) the City Area Model traces user motion at an area zone level, (b) the Area Zone Model considers users moving on a street network and (c) the Street Unit Model tracks user motion with an accuracy of a few meters. The validity of the basic models for mobile communications ’ design aspects is highlighted. Moreover, an "integrated mobility modeling tool”, which considers the basic mobility models as components is proposed, aiming at the development of a refined modeling approach. This is achieved by improving the accuracy of the input parameters of each basic model, via the exchange of some specific (mobility related) parameters among the component models. To justify the applicability of the proposed integrated tool for both the analysis of design aspects and network planning, indicative results are presented, derived from simulation-based application examples of the three basic mobility models. 1

Video-to-video e-Health applications supporting medical use cases for remote patients

Information and Communication Technologies (ICT) relevant to health and healthcare systems can rise their effectiveness, expand quality of life and “reveal” innovation and novelty in modern health-related markets, thus implicating options for further growth. The broadly used term “e-Health” regularly implicates the use of ICT in health products, services to improve health of citizens, efficiency and productivity in healthcare delivery, and the economic and social value of health, in general. In this end, the LiveCity Project aims at empowering the citizens of a city to interact with each other in a more productive, efficient and socially useful way, by using high quality video-to-video (v2v) over the Internet. In this work, the LiveCity platform for e-Health is presented, along with two use cases for remote patients telemonitoring and emergency cases. © IFIP International Federation for Information Processing 2014
