Semantics and Syntax: A Legacy of Alan Turing

In this talk I will present two approaches towards modular security proofs for the composition of key exchange protocols with arbitrary other cryptographic tasks. While the two approaches differ in their scope and applicability they both rely on game-based security security and avoids the idiosyncrasies of simulation-based definitions. As an application, I will discuss how the results can be applied to proving the security of the Transport Layer Security protocol.
