As quantum computing advances, the standards for Post-Quantum Cryptography (PQC) are evolving rapidly, with governments like Australia phasing out even selected PQC algorithms like ML-KEM-768 and ML-DSA-65 to maintain robust security. This article explores the challenges businesses face in adapting to these shifting standards, from resource demands to compliance across jurisdictions. It highlights the importance of cryptographic agility and collaboration to navigate this dynamic landscape and stay secure against future quantum threats.
