HPE has integrated post-quantum cryptography into its latest iLO management controllers to protect server firmware against future threats. The Gen12 hardware utilizes NIST-standardized algorithms, specifically Leighton-Micali Signatures and Module-Lattice-Based Digital Signature Algorithm, to secure the boot process. These mathematical approaches are designed to resist decryption attempts from quantum computers, addressing the "save now, decrypt later" strategy used by some adversaries.

Microsoft is accelerating its transition to post-quantum cryptography (PQC) due to rapid advancements in quantum computing that threaten current encryption standards. The company now aims to migrate its critical products and services to quantum-resistant algorithms by 2029 through its Quantum Safe Program. This shift addresses "harvest now, decrypt later" risks, where attackers collect encrypted data today to decrypt it once powerful quantum computers become available.
