Classic McEliece, a code-based post-quantum cryptography algorithm developed by UK firm Post-Quantum, has been integrated into ISO/IEC 18033-2, making it the first PQC algorithm to achieve global standardisation under this asymmetric cipher standard. The algorithm is now available for adoption across ISO's 177 member states and is already recommended by German and Dutch national security agencies for protecting long-shelf-life data and has been deployed on battlefield drones.

◆ ◆ The Wire takeaway
You can now sell encryption that governments and enterprises will actually buy without a five-year approval cycle. Classic McEliece is in the ISO standard, which means your customer's compliance officer stops blocking the deal—and defence primes building quantum-resistant systems need suppliers who can embed it yesterday.
