Lower Bounds for Local Monotonicity Reconstruction from Transitive-Closure Spanners
Abstract. Given a directed graph G = (V, E) and an integer k 1, a ktransitive-closure-spanner (k-TC-spanner) of G is a directed graph H = (V, EH ) that has (1) the same transitive...

New Constructive Approach to Covert Channel Modeling and Channel Capacity Estimation
In this paper, we examine general mechanisms that a covert channel may exploit and derive new minimum requirements for setting up a covert channel. We also propose a new classifica...
