1.1.3 (SAM); This project aims to take an information theoretic view on the investigation of the fundamental limits of cryptographic primitives. Most existing literature in theoretical computer science community considers the complexity theoretic formulation that focuses on performance metrics along different scaling laws when compared to our Shannon theoretic formulation that concentrates on the landmark information theory concept - capacity. This viewpoint has been successfully applied by the PI to unravel insights on the fundamental capacity limits of several canonical cryptography problems such as broadcast encryption, conditional disclosure of secrets, and secure multiparty computation. Alongside, inspired by recent advances in network information and coding theory, a set of sophisticated mathematical tools have been developed over the past several years and are expected to play instrumental roles in the proposed study, including but not limited to: interference alignment based code design, generic subspace codes, linear dimension counting, information inequalities framework for converse derivation, and random binning and algebraic codes. The PI, as a key contributor of these techniques, will apply and further develop them in the context of the proposed study.
