Core engineering and protocols for DO-254 DAL-A Hardware Certification.
In commercial aviation, DAL-A is the most stringent safety certification tier, reserved for systems whose malfunction could result in catastrophic failure of the aircraft. Developing a post-quantum cryptographic vault for DAL-A avionics requires full traceability from high-level safety requirements down to individual silicon gates, accompanied by extensive physical fault injection and hardware verification.
AvionicsVault incorporates dual-channel lockstep processing: two identical, physically separated ML-KEM/ML-DSA cores compute every operation in parallel. A majority-voter comparator checks outputs on every clock cycle; any discrepancy immediately triggers safe-state fallback and asserts an alert to the aircraft avionics maintenance computer.
