The National Institute of Standards and Technology (NIST) has released a high‑level roadmap, NISTIR 8547, to guide organizations in transitioning from quantum‑vulnerable cryptographic algorithms to the post‑quantum standards finalized in 2024. The report identifies which current algorithms are at risk, outlines federal migration timelines (2030 for key establishment, 2031 for digital signatures, and 2035 for full federal systems), and offers practical guidance on prioritizing upgrades, managing the cryptographic supply chain, and considering hybrid approaches to mitigate the “harvest‑now, decrypt‑later” threat. It also complements NIST’s National Cybersecurity Center of Excellence project, which provides tools and demonstrations to support the migration. https://www.nist.gov/news-events/news/2026/09/nist-report-provides-guidelines-transition-post-quantum-cryptography
