Current cloud computing infrastructure offerings are lacking in interoperability, which is a hindrance to the advancement and adoption of the cloud computing paradigm. As clouds ar...
Secure multiparty computation allows parties to jointly compute a function of their private inputs without revealing anything but the output. Theoretical results [2] provide a gen...
Abstract. In this work we will show how non-qualified electronic signatures and time stamps can be efficiently enhanced in order to equip them with similar features as qualified ...
In this paper we introduce Social VPNs, a novel system architecture which leverages existing social networking infrastructures to enable ad-hoc VPNs which are self-configuring, s...
