America’s principal standards agency has issued new guidance on how organizations should move away from encryption algorithms that might one day be broken by sufficiently powerful quantum computers. The National Institute of Standards and Technology released its October 27, 2026 announcement alongside Transition to Post-Quantum Cryptography Standards, NIST Internal Report 8547.
Why cybersecurity is moving before the threat arrives
Quantum computers with enough capability to compromise certain widely used public-key cryptographic methods are still under development. But encrypted information stolen today could potentially be saved for later decryption, a risk security specialists call “harvest now, decrypt later.” That creates a reason to act before the relevant quantum hardware exists.
NIST finalized three initial post-quantum cryptographic standards in 2024. Its new 2026 report is a roadmap for adopting those standards, identifying vulnerable older algorithms and considering the different needs of organizations, vendors and federal systems.
What the milestones mean
According to NIST, federal high-value assets and high-impact systems face accelerated targets: migration for key-establishment technologies by 2030 and for digital signatures by 2031. A broader federal migration target of 2035 was established previously. These deadlines have specified federal scope; they should not be portrayed as blanket legal mandates for every private business.
A practical checklist for organizations
Operators should first identify where cryptography is used: websites, identity systems, payment services, document signatures, messaging and systems supplied by outside vendors. Organizations should examine which information must remain confidential for many years, how software and hardware can be updated, and whether a phased or hybrid transition is appropriate. NIST notes that combining conventional and post-quantum mechanisms can reduce some transition uncertainty, though it may demand more resources.
Watch: expert discussion of quantum-safe migration
The following independent 2025 discussion features specialists addressing the move from standards to practical implementation. It provides background and does not replace or document the October 2026 NIST publication.
