Western Digital to integrate post-quantum cryptography into hard drives

Western Digital said on May 19 it integrated post-quantum cryptography into its latest high-capacity Ultrastar UltraSMR hard disk drives. The company said it will introduce HDDs that apply quantum-resistant algorithms approved by the U.S. National Institute of Standards and Technology. Western Digital said the move shows quantum security is shifting from theory to hardware-level defense and could help protect large-scale data lakes backing AI innovation from future quantum computers.
