Vladimir Soukharev, Cryptographer, InfoSec Global Inc. Practical quantum technologies, that would allow to build a large-scale quantum computer, have been actively emerging. According to some experts, it might take another 15-20 years to be able to build one. Quantum computers will open new capabilities for the world. However, in the hands of malicious adversaries, they could become a real threat. All of today’s standardised public-key cryptography could be efficiently broken by large-scale quantum computers. For a number of reasons, protection against this threat is required to be available now or in near future. Still, using quantum techniques for protection is not yet feasible. Hence, the solution is to apply Post-Quantum Cryptography in order to build classical cryptographic schemes that would be quantum-resistant. In this presentation, we give an overview of technical capabilities of quantum computers and describe the currently available methods of protection against them. We observe the recent developments in Post-Quantum Cryptography and explain how to integrate them into classical cryptographic schemes today, to be protected in due time. We concentrate on Post-Quantum solutions based on elliptic curves, namely elliptic curve isogenies. We will present a quantum-resistant key agreement and public key encryption algorithms based on elliptic curve isogenies. Other schemes, based on these cryptographic primitives, will also be discussed.
