Policy Gradient Methods for Information-Theoretic Opacity in Markov Decision Processes

Chongyang Shi, Sumukha Udupa, Michael R. Dorothy +2

Opacity, or non-interference, is a property ensuring that an external observer cannot infer confidential information (the "secret") from system observations. We introduce an inform…

Synthesis of Dynamic Masks for Information-Theoretic Opacity in Stochastic Systems

Sumukha Udupa, Chongyang Shi, Jie Fu

In this work, we investigate the synthesis of dynamic information releasing mechanisms, referred to as ''masks'', to minimize information leakage from a stochastic system to an ext…
