Secret-key cryptography from ideal primitives: A systematic overview

Secret-key cryptography from ideal primitives: A systematic overview Secret-key constructions are often proved secure in a model where one or more underlying components are replaced by an idealized oracle accessible to the attacker. This model gives rise to information-theoretic security analyses, and several advances have been made in this area over the last few years. This paper provides a systematic overview of what is achievable in this model, and how existing works fit into this view.
