Quantum computing presents a major challenge to traditional cryptography, threatening to break widely used encryption methods. Andrew Lord dives into how quantum computers could undermine current security systems and what’s being done to mitigate the risk. Learn about Post-Quantum Cryptography (PQC) and Quantum Key Distribution (QKD), two critical approaches to safeguarding data in the quantum era. Gain insights into how organisations are preparing for the shift to quantum-resistant security.
