Trusted Execution & Key Protection
Trusted execution technologies are powerful, but they are often misunderstood. A TEE, TrustZone design, secure element, TPM, HSM, or enclave does not automatically protect secrets unless the architecture uses it correctly.
Device Prophet reviews trusted execution and key-protection designs to validate what is isolated, what is exposed, and where trust assumptions may fail.
Typical scope
- · TrustZone / TEE partitioning
- · Secure-world and normal-world boundary review
- · Key storage and key-use model
- · Secure element / TPM / HSM integration assumptions
- · Device identity and attestation model
- · Secure API and attack-surface review
- · Update and lifecycle implications
Outcome
You receive a written review of trust boundaries, what is enforceable in your trusted-execution design, where assumptions may not hold, and how to harden the architecture.
Our review process may use AI-assisted research and mapping to speed up standards analysis, requirement discovery, and preparation. Final findings and technical recommendations are reviewed by human embedded-security expertise.
