Modern autonomous vehicles run multi-billion-parameter neural networks and communicate across public 5G base stations. A software compromise must never compromise the vehicle's cryptographic roots of trust. An EVITA Full Hardware Security Module acts as a sovereign micro-citadel embedded inside the central SoC die, guarding firmware update certificates, V2X public keys, and disk encryption master keys from physical and logical intrusion.
Adversaries with physical access to an ECU can record micro-variations in power supply current (Differential Power Analysis) or electromagnetic radiation during AES or ECC calculations to deduce the private key bit by bit. EVITA Full hardware integrates internal noise generators, dual-rail pre-charge logic, and arithmetic masking. Furthermore, all cryptographic primitive libraries execute in mathematically identical clock cycles regardless of whether a bit is zero or one.
