Western Digital Adds Post-Quantum Cryptography to Hard Drives

AI-summarised brief · reviewed before publication

Western Digital has announced the integration of NIST-approved post-quantum cryptography into its new Ultrastar UltraSMR hard drives. This marks one of the first deployments of quantum-resistant security in production storage infrastructure for AI-era data systems. The drives are designed to defend against "harvest now, decrypt later" threats and firmware-level attacks. They are currently being qualified by multiple hyperscale customers as enterprises prepare for long-term cryptographic risks tied to future quantum computers.
