In-network aggregation is an essential primitive for performing queries on sensor network data. However, most aggregation algorithms assume that all intermediate nodes are trusted...
Abstract. Recently, efficient leader election algorithms for ad hoc radio networks with low time complexity and energy cost have been designed even for the no-collision detection,...
An important factor in the successful deployment of federated web-services-based business activities will be the ability to guarantee reliable distributed operation and execution....
Keystroke dynamics—the analysis of typing rhythms to discriminate among users—has been proposed for detecting impostors (i.e., both insiders and external attackers). Since man...
We consider a set of clients collaborating through an online service provider that is subject to attacks, and hence y trusted by the clients. We introduce the abstraction of a fai...
