AUTOSAR Secure Onboard Communication (SecOC): AES-128 CMAC and Truncation Strategies
Standardizing cryptographic message authentication across CAN-FD frames to guarantee payload integrity, sender authenticity, and non-repudiation.
CAN Bus Transmission Security, AUTOSAR SecOC & Anti-Replay Engine
Hardening in-vehicle networks against spoofing, replay, and masquerade attacks with hardware-accelerated AUTOSAR SecOC, AES-128 CMAC authentication, and synchronization.
Engineering Specifications
Freshness Value Management (FVM): Anti-Replay Counter Synchronization over CAN-FD
Defeating replay attacks using multi-tier monotonic freshness counters and trip-counter synchronization across distributed vehicle nodes.
HSM-Assisted Hardware MAC Generation & Verification at Line Rate (5 Mbps)
Leveraging dedicated on-chip Hardware Security Modules (EVITA Medium) to verify hundreds of authenticated frames per second without CPU degradation.
