Sistemi di Aggiornamento Software di Bordo Protetti da Uptane

AutomotiveOTA definisce l'implementazione ingegneristica dello standard di sicurezza Uptane per veicoli connessi. Disaccoppiando i repository Image e Director e applicando un protocollo two-phase commit tra le ECU, garantisce aggiornamenti a tempo zero di inattività.

Prevenire la Compromissione dei Server e Mitigare gli Attacchi Man-in-the-Middle

I sistemi OTA tradizionali dipendono da semplici connessioni TLS verso un unico server cloud. In caso di violazione, gli aggressori possono distribuire firmware malevolo a milioni di veicoli. Uptane elimina questo singolo punto di vulnerabilità richiedendo firme crittografiche separate da un repository Image offline e da un repository Director online.

Core Engineering Areas

• Uptane Security Framework — Implementing the Uptane standard (IEEE-ISTO 6100) separating Image and Director repositories to protect fleets even if OEM cloud servers are breached.
• Differential Delta Compression — Using instruction-aware differential compression algorithms (Courgette, bsdiff) to transmit only binary diffs over cellular networks.
• Atomic Multi-ECU Orchestration — Coordinating complex multi-ECU dependency graphs: ensuring powertrain, braking, and radar nodes switch versions simultaneously during key-off.
