Hardware Root of Trust with Secure Boot
Implement a hardware-anchored verified/measured boot chain with attestation and anti-rollback on a real embedded platform.
Embedded and IoT devices frequently boot unsigned firmware, allowing attackers with physical or supply-chain access to implant persistent, OS-invisible bootkits that survive reflashing and factory resets. Without a hardware-anchored root of trust, there is no cryptographic guarantee that the first code executed is authentic and unmodified. This gap undermines device identity, remote attestation, and every higher-layer security control that assumes a trustworthy platform.
**What you'll build**
Establish a measured and verified boot chain anchored in immutable hardware (fuse-burned public key hash, TPM/secure element, or MCU secure-boot ROM) where each stage cryptographically verifies the next before transferring control. Integrate a TPM 2.0 or secure element for key storage, PCR measurement, and remote attestation, and implement anti-rollback via monotonic counters. Demonstrate the full chain from ROM to signed bootloader to signed kernel/application with tamper and downgrade protection.
**Objective** — Implement a hardware-anchored verified/measured boot chain with attestation and anti-rollback on a real embedded platform.
**Expected outcome** — A device that refuses unsigned or downgraded firmware, produces a TPM/secure-element attestation quote, and a documented threat model plus verification test suite.
**Difficulty** — Expert — demands applied cryptography, low-level firmware, TPM/secure-element programming, and hardware fusing that is unforgiving of error.
