About this tag
The root-of-trust tag covers discussions about hardware-based security foundations, particularly Microsoft's Azure Integrated HSM and the open-source Caliptra 2.0 root-of-trust. These technologies establish discrete security boundaries at the silicon level, protecting cryptographic keys and enabling confidential computing at hyperscale. Related topics include post-quantum cryptography accelerators, NVMe key management, and Secure Boot certificate management for Windows systems. The content emphasizes how roots of trust are evolving from centralized appliances to per-server silicon modules to address multi-tenant isolation, insider threats, and compliance with Microsoft's security standards.
