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…

Reactive Synthesis of Sensor Revealing Strategies in Hypergames on Graphs
Sumukha Udupa, Ahmed Hemida, Charles A. Kamhoua +1
In many security applications of cyber-physical systems, a system designer must guarantee that critical missions are satisfied against attacks in the sensors and actuators of the C…
