What is Post-Quantum Cryptography?

Post-quantum cryptography, also referred to as quantum-resistant or quantum-proof cryptography, is a specific type of cryptographic computing architecture that utilizes public-key cryptography (PKC) and is characterized by the ability to prevent quantum computing attacks. At this time, most experts in the field believe that existing computing systems are quantum-resistant, however, the potential for quantum computing attacks designed to exploit current computing infrastructure remains a real possibility. For this reason, the ongoing research and development of quantum-proof computing systems remains a high priority for cryptographers and computer scientists across the globe.
