Information Theoretic Methods in Cybersecurity

Information theoretic security offers the strongest possible security guarantees, since information theoretically secure keys are unbreakable in principle, without the need for any hardness assumption. This project studies information theoretic key generation in the context of the Internet of Things (IoT), for which a large number of agents of limited capabilities and secret keys need to be created on demand by subsets of these agents for specific applications. The architecture envisioned is a process of interactive message exchanges that creates a distributed approximately shared key, from which, on demand, subsets of nodes can extract a secure key when needed.
