A hardware-enforced trust chain architecture with formal verification for secure boot and key management lifecycle. The project leverages Z3 SMT Solver to formally verify security properties of the boot chain, ensuring that each stage of the boot process is cryptographically authenticated before execution.
Key contributions:
- Formal verification framework for secure boot sequences using Z3 SMT Solver
- Key management lifecycle with hardware-backed key storage and rotation
- ML-based runtime validation for continuous trust chain integrity monitoring
- Integration with ARM and RISC-V security subsystems
This work was conducted at the Technology Innovation Institute (TII) as part of the Secure Systems Research Centre’s mission to build verifiably secure embedded platforms.
