Open-source silicon Root of Trust (RoT) security subsystem designed for integration into SoCs. Provides identity, measured boot, and attestation capabilities. Founded by Microsoft, AMD, Google, and NVIDIA in 2022 under the CHIPS Alliance. Version 2.1 adds quantum-resilient cryptography (ML-DSA for post-quantum signatures, ML-KEM for key exchange). ~1.6M logic gates with dual RISC-V cores. Potentially the most promising cross-vendor foundation for hardware-enabled AI governance.

1| FlexHEG (Flexible Hardware-Enabled Guarantees) | Research project led by Yoshua Bengio developing open-source hardware-enabled guarantees for AI governance. Proposes a "Guarantee Processor" that monitors accelerator usage and verifies compliance, combined with a "Secure Enclosure" providing physical tamper protection. Funded with $4.1M from the Survival and Flourishing Fund (2024). Published interim report (September 2024), technical options paper (arXiv:2506.03409), and international security applications paper (arXiv:2506.15100). Interlock-based design gives the Guarantee Processor direct access to the accelerator data path. Estimated 3.7-7.9 years for integrated hardware deployment. |
