In recent years, the threat to the public key infrastructure posed by quantum computers has gained some attention. Standards agencies such as NIST and ETSI have begun efforts to standardize encryption and signature algorithms that are quantum resistant. This talk will introduce attendees to the threat posed by quantum computing and explain which parts of the cryptography we use today is threatened. We will then briefly explain the different families of quantum-resistant algorithm proposed to NIST. We will explain where to find implementations of those algorithms and how to integrate them to your security infrastructure. After attending this talk, you should have a high-level understanding of why quantum computing is threatening cryptography, why this is bad, what are the proposed solutions and how they work. I will also discuss performance comparison of quantum-resistant algorithms, where to find open-source implementations and how to integrate them to existing protocols such as SSH or TLS.
