IC Colloquium: Building Cryptography in a Quantum World
By: Nicholas Spooner - University of Warwick
Abstract
It is by now well-established that many cryptographic protocols will be rendered insecure if sufficiently powerful quantum computers are built. While this remains at least a few decades away, there is another, more immediate, problem: the mathematical arguments that we use to establish cryptographic security rely on properties of classical information that do not hold in the quantum setting. This renders the security of such schemes unclear, against even very rudimentary quantum computers. In this talk I will present techniques I have developed to address this challenge, and discuss how we might rebuild the foundations of cryptography for the quantum era.
