Abstract. A group key agreement protocol allows a set of users, communicating over a public network, to agree on a private session key. Most of the schemes proposed so far require ...
We present a new undeniable signature scheme which is based on the computation of characters. Our signature scheme offers the advantage of having an arbitrarily short signature. I...
We develop a framework for the image segmentation problem based on a new graph-theoretic formulation of clustering. The approach is motivated by the analogies between the intuitiv...
Overlay broker networks are an important part of an eventbased middleware. In this paper, we investigate the requirements of overlay broker networks and argue that using peer-to-p...
Previous methods have generally identified the location of a type error as a particular program point or the program subtree rooted at that point. We present a new approach that ...
