As the next evolutionary step, social networking will evolve towards user communities that are dynamically established according to contextual aspects such as the shared location and/or activities of people. In this vision, distributed peer-to-peer (P2P) technologies provide a respectable alternative to ...

Works in communication security policy have recently focused on general-purpose policy languages and evaluation algorithms. However, because the supporting frameworks often defer enforcement, the correctness of a realization of these policies in software is limited by the quality of domain-specific implementations. This paper introduces the Antigone communication security policy enforcement fra...

We are interested to understand whether crowdsourcing represents a robust strategy that can be used in conjunction with c...

The capabilities of the conceptual link between threshold gates and sorting networks are explored by implementing a which uses a sorter as the main building block. Traditional disadvantages of binary sorters such as their hardware intensive nature are avoided by using νMOS circuits which allow to improve previous results for multipliers based on a similar architecture.
