Western Digital Launches PQC-Enabled Drives to Combat Quantum Threats

• •WD's Ultrastar DC HC6100 drives now feature post-quantum cryptography to enhance security.
• •The PQC implementation aims to protect against HNDL attacks, where data is collected for future decryption.
• •These drives are currently being qualified with hyperscale customers, reflecting significant industry interest.

Western Digital Corporation announced the integration of post-quantum cryptography (PQC) into its Ultrastar DC HC6100 UltraSMR hard disk drives to protect against 'harvest now, decrypt later' (HNDL) attacks. These attacks involve adversaries collecting encrypted data today to decrypt it once quantum computing capabilities advance. The new drives utilize NIST-approved ML-DSA-87 algorithms to safeguard firmware integrity and device trust chains, rather than focusing solely on data-at-rest encryption. This move reflects a broader industry shift towards quantum-resilient storage solutions as AI-generated data becomes increasingly valuable. The drives are currently in qualification with multiple hyperscale customers, indicating strong market interest. The announcement emphasizes the urgency for organizations to prepare for long-term cryptographic resilience against evolving threats. Dr. Xiaodong Che, WD's CTO, highlighted the necessity of evolving security architectures to address these emerging challenges.
