Abstract: Obscuring sensitive data from adversarial eavesdropping in distributed decision-making is a significant challenge across a range of applications, including smart grids, autonomous vehicle coordination, and multi-robot surveillance. Existing methods—such as encryption or differential privacy—modify transmitted messages without considering the underlying dynamics of the cyber-physical processes that generate the data, nor the capabilities of potential adversaries. In our recent work, we demonstrate that every dynamical system possesses an inherent system-level privacy that can be harnessed through the design of intelligent inter-agent communication protocols.
In this talk, I will present our recent results on extracting system-level privacy in the presence of eavesdropping adversaries. We derive analytical expressions that quantify the level of protection as a function of both the adversary’s capabilities and the agent communication graph. Finally, I will show how these results can be applied in the context of distributed optimization and federated learning.
