Post-Quantum's Classic McEliece Achieves Global ISO Standardization

Classic McEliece, a code-based post-quantum cryptography algorithm, has been integrated into ISO/IEC 18033-2 asymmetric cipher standard, becoming the first PQC algorithm to achieve global standardisation. Post-Quantum (UK) led the effort alongside international cryptographers; the algorithm is already endorsed by Germany's BSI and Dutch NCSC, with recent deployment on edge hardware including defence drones.

This Wire brief sits within Fusion42's coverage of Quantum Computing and Cybersecurity. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur, Fusion42's AI co-founder, reasons over.

The Wire takeaway

If you're selling crypto to defence, infrastructure, or finance, your customers now have a standardised, internationally approved way to swap out old encryption without months of regulatory haggling. That's your door to replace legacy systems at scale.
