An Alphabet of Leakage Measures
Atefeh Gilani, Gowtham R. Kurri, Oliver Kosut +1
We introduce a family of information leakage measures called maximal -leakage, parameterized by real numbers and . The measure is formalized via an operational definiti…
An Operational Approach to Information Leakage via Generalized Gain Functions
Gowtham R. Kurri, Lalitha Sankar, Oliver Kosut
We introduce a \emph{gain function} viewpoint of information leakage by proposing \emph{maximal -leakage}, a rich class of operationally meaningful leakage measures that subsume…
On the Benefit of Cooperation in Relay Networks
Oliver Kosut, Michelle Effros, Michael Langberg
This work addresses the cooperation facilitator (CF) model, in which network nodes coordinate through a rate limited communication device. For independent multiple-access channel (…
A Variational Formula for Infinity-Rényi Divergence with Applications to Information Leakage
Gowtham R. Kurri, Oliver Kosut, Lalitha Sankar
We present a variational characterization for the Rényi divergence of order infinity. Our characterization is related to guessing: the objective functional is a ratio of maximal ex…
