Secure Boot & Root of Trust Review
Secure boot is not only about enabling a feature in the datasheet. The real question is whether the full boot chain, signing model, rollback protection, lifecycle states, key hierarchy, recovery path, and production process work together.
Device Prophet helps design, implement and review boot chains, signing workflows, rollback protection and recovery.
Typical questions
- · What is the immutable trust anchor?
- · Which keys sign which stages?
- · Can an attacker downgrade firmware?
- · How are debug and recovery handled?
- · What happens if a signing key is compromised?
- · Are fuse states and lifecycle states correctly planned?
- · Can manufacturing provision devices safely?
Outcome
For implementation work, receive the agreed code or configuration changes and checks. A review provides findings and recommended changes to the boot chain, keys, rollback and provisioning.
