Covert Ephemeral Communication in Named Data Networking

In the last decade, there has been a growing realization that the current Internet Protocol is reaching the limits of its senescence. This has prompted several research efforts that aim to design potential next-generation Internet architectures. Named Data Networking (NDN), an instantiation of the content-centric approach to networking, is one such effort. In contrast with IP, NDN routers maintain a significant amount of user-driven state. In this paper we investigate how to use this state for covert ephemeral communication (CEC). CEC allows two or more parties to covertly exchange ephemeral messages, i.e., messages that become unavailable after a certain amount of time. Our techniques rely only on network-layer, rather than application-layer, services. This makes our protocols robust, and communication difficult to uncover. We show that users can build high-bandwidth CECs exploiting features unique to NDN: in-network caches, routers' forwarding state and name matching rules. We assess feasibility and performance of proposed cover channels using a local setup and the official NDN testbed

FIT for purpose – the new FLARE Index to Treaties

The FLARE Index to Treaties which was launched in March 2009 on the Institute of Advanced Legal Studies web server, was conceived to fill a gap in the range of information finding tools available on the internet for the international lawyer. It is a fully searchable database indexing and listing over 1,500 of the most significant multilateral treaties concluded from 1856 onwards. This article describes the background to the development, the various ways in which the service can be used and technical issues in its construction and use.Preprint of an article by Dr Peter Clinch, Senior Subject Librarian for Law, Cardiff University, Wales, UK and Steven Whittle, Information Systems Manager, Institute of Advanced Legal Studies, University of London published online by LLRX.co
