Post-Quantum Cryptography: Preparing for the Quantum Threat 🔐

Emerging quantum technologies will break currently deployed public-key cryptography which is one of the pillars of modern-day cybersecurity. Thus we need to migrate our systems and practices to ones that are quantum-safe before large-scale quantum computers are built. There are viable options for quantum-proofing our cryptographic infrastructure, but the road ahead is neither easy nor fast. Impressive progress in developing the building blocks of a fault-tolerant scalable quantum computer indicates that the prospect of a large-scale quantum computer is a medium-term threat. I believe organizations will soon be distinguished by whether or not they have a well-articulated plan for mitigating this quantum risk. I will discuss the quantum threat to cybersecurity and the process for mitigating the risk.
