Zonal Bus Microsegmentation & SecOC
AUTOSAR Secure Onboard Communication (SecOC) authenticating chassis, powertrain, and steer-by-wire frames using cryptographic MAC tags and freshness values.
Sub-50 Microsecond MAC Verification
Dedicated hardware crypto coprocessors calculate AES-128-CMAC tags directly in the CAN XL controller network interface without CPU intervention, preventing denial-of-service bus delays.
- AES-128 CMAC authentication on all CAN-XL and Ethernet frames.
- Zero possibility of unauthorized ECU command injection.
- Dynamic freshness value management preventing replay attacks.
- Packet filtering firewalls isolating infotainment from powertrain networks.
