U.S. sets 2027 PQC deadline for national security acquisitions as Intel ships quantum-safe Xeon 6
↗
The U.S. government has mandated that new national security system acquisitions support post-quantum cryptography algorithms by January 2027, with full adoption targeted by 2035, while Intel's Xeon 6 processors already ship with quantum-safe memory encryption and microcode signing.
Engineers managing systems with data confidentiality requirements beyond 10 years face a 'harvest now, decrypt later' threat where adversaries stockpile encrypted data for future quantum decryption. The government timelines give commercial enterprises reference points for calibrating their own PQC migration, and hardware with quantum-resistant capabilities is already shipping to handle the computational overhead that post-quantum algorithms introduce.

U.S. directives require new national security system acquisitions to support CNSA 2.0 PQC algorithms by January 2027, with implementation required by 2031 and 100% adoption targeted by 2035.
A Global Risk Institute survey of 32 quantum computing experts found a 50-50 probability that quantum computers could break a 2048-bit RSA key within 24 hours by 2040.
Intel Xeon 6 processors already ship with AES-256 quantum-safe memory encryption and microcode signing, with upcoming platforms extending PQC to firmware signing, device interconnects, attestations, and secure boot.
