Dynamic Root of Trust Challenges and Flashpoint's Approach

Modern platforms place a large and complex firmware stack in the highest privilege mode, including bootloaders, initialization code, device drivers, third-party libraries, run-time firmware, and security monitors, so a small bug in any trusted component can compromise the entire system.

Static Root of Trust measures this whole stack from boot, creating an unnecessarily large trusted computing base, while a Dynamic Root of Trust aims to remove boot-time firmware from that base by using untrusted firmware to trigger a trusted dynamic launch anchor.

This creates a bootstrap paradox: software that may already be malicious must invoke the very mechanism that restores trust, yet without isolation at the highest privilege level it can leak secrets, forge measurements, or prevent control from reaching trusted run-time firmware.

Existing approaches narrow this gap with vendor-specific microcode, special hardware privileges, de-privileging, or binary analysis, but they do not generally solve the core problem: without strong isolation in the highest privilege mode, code running there cannot safely be treated as untrusted.
