In an era where quantum computing edges closer to practicality, the cryptographic protocols we rely on must evolve to meet emerging challenges. Post-Quantum Cryptography (PQC) represents a proactive step towards safeguarding sensitive information against quantum-powered threats. However, as with any technology at the frontier of innovation, PQC standards are not set in stone. The Changing Face of PQC Standards The Australian government’s recent cryptography guidelines highlight a critical reality: even within the realm of quantum-resistant algorithms, change is inevitable. Algorithms like ML-KEM-768 and ML-DSA-65, which were once heralded as secure and Post-Quantum solutions, are now to be phased out in 2030....
