On November 12, 2024, NIST released the initial public draft of NIST Internal Report 8547, “Transition to Post-Quantum Cryptography Standards.” The report describes NIST’s expected approach to deprecating quantum-vulnerable cryptographic algorithms and migrating to post-quantum alternatives.
IR 8547 proposes deprecating public-key algorithms at approximately 112-bit security (such as RSA-2048 and P-256) by 2030 and disallowing all quantum-vulnerable public-key algorithms by 2035. The report identifies the three finalized PQC standards (FIPS 203, 204, and 205) as the foundation for migration. Public comments were accepted through January 10, 2025.
