Core engineering and protocols for ARINC 653 Partitioned Key Isolation.
Modern commercial airliners (such as the Boeing 787 and Airbus A350) utilize Integrated Modular Avionics (IMA), where multiple airborne software functions share common computing platforms. ARINC 653 establishes strict spatial and temporal boundaries, ensuring that a software glitch or compromise in a lower-criticality partition (e.g., passenger Wi-Fi) can never exhaust CPU time or access memory belonging to critical flight control partitions.
AvionicsVault hosts all post-quantum private keys inside a dedicated, high-priority ARINC 653 secure partition. Other flight systems request cryptographic services exclusively through memory-protected queuing ports, ensuring that raw key material is never exposed across the avionics backplane.
