WhatA hardware security module or firmware-level solution providing post-quantum roots of trust for TEEs, TPMs, and secure boot chains that current silicon vendors have failed to update.
SignalThe article explicitly calls out that TEEs like SGX and SEV-SNP, plus TPM chips underpinning measured boot, have non-PQ keys baked in with no visible path to replacement — meaning the entire hardware trust foundation is at risk.
Why NowHash-based signature schemes suitable for hardware attestation have been stable for years, the NIST PQ standards are finalized, and the compressed quantum timeline means existing hardware roots of trust may be compromised before their natural replacement cycle.
MarketServer manufacturers (Dell, HPE, Lenovo), cloud providers (AWS, Azure, GCP), and chip vendors (Intel, AMD); TAM is tied to the server and endpoint security market worth tens of billions. No one is shipping PQ attestation roots today.
MoatHardware-level integration and OEM partnerships create enormous switching costs and long certification cycles that lock out later entrants.
