EvtolSecurity: Arquitetura de Cibersegurança para eVTOL e Aeronavegabilidade DO-326A

EvtolSecurity Multi-Domain Aviation Cybersecurity Architecture

Aircraft Control Domain boundary, cryptographic HSM root of trust, and intrusion detection engine

Central System: Aviation Security Gateway - DO-326A Airworthiness Firewall

Aviation Architecture Nodes

• Aircraft Control Domain (ACD)
• Hardware Cryptographic HSM Core
• Deep Packet Inspection (DPI) Filter
• Passenger Information Domain (PIESD)
• Airline Security Operations Center (SOC)

Architectural Layers & Protocol Stacks

• Aircraft Network Domain Segregation (ARINC 811 / RTCA DO-326A Security Architecture): Physically and logically isolating the Aircraft Control Domain (ACD) from public passenger networks and wireless ground maintenance.
• Hardware Root of Trust & Secure Boot (Hardware Security Module (HSM) / FIPS 140-3 Level 3): Cryptographically verifying firmware signatures on every microcontroller before authorizing flight code execution.
• Airborne Intrusion Detection & Prevention (Deterministic eBPF Filters / Bus Anomaly AI): Monitoring internal avionics buses (CAN, Ethernet) at wire speed, intercepting unauthorized injection commands instantly.
• Continuous Airworthiness Security (DO-328A) (Automated Software Bill of Materials (SBOM)): Continuously monitoring third-party software libraries for emerging CVE vulnerabilities throughout airframe lifespan.

Flight Telemetry Metrics: 100% (Network Domain Physical Isolation) | DO-326A (Airworthiness Security Compliance) | < 10 µs (Hardware Firewall Packet Filtering) | FIPS 140-3 (Cryptographic HSM Enclave)
