Most protocols for distributed, fault-tolerant computation, or multi-party computation (MPC), provide security guarantees in an all-or-nothing fashion: If the number of corrupted p...
This demo presents a privacy-preserving aggregate location monitoring system, namely, TinyCasper, in which we can monitor moving objects in wireless sensor networks while preservi...
Distance bounding protocols have been proposed for many security critical applications as a means of getting an upper bound on the physical distance to a communication partner. As...
Fair exchange is one of the most fundamental problems in secure distributed computation. Alice has something that Bob wants, and Bob has something that Alice wants. A fair exchang...
In this paper we present our authorization framework that supports the dynamic set-up of Web service federations for sharing data within virtual federations. Building on previous w...
