These sources collectively address the emerging cybersecurity threat posed by quantum computing, which has the potential to break current encryption standards like RSA and ECC. To counter this, experts advocate for a transition to post-quantum cryptography (PQC), utilizing new algorithms like ML-KEM and ML-DSA that are designed to withstand quantum attacks. Organizations are encouraged to adopt crypto-agility, a flexible framework that allows for the rapid replacement of outdated security protocols as the landscape evolves. The documentation highlights the dangerous “Store Now, Decrypt Later” strategy, where malicious actors collect encrypted data today to unlock it once powerful quantum hardware is available. Leading institutions such as NIST and Orange Cyberdefense provide roadmaps for this migration, emphasizing the need for cryptographic inventories and hybrid deployment models. Ultimately, the materials serve as a strategic guide for businesses and government agencies to secure their digital infrastructure before the arrival of the “Q-Day” milestone.
