Zonal ECUs have improved efficiency but also widened the attack surface. TEE based security tackles this by isolating sensitive operations like secure boot, firmware validation, and key storage, ensuring a resilient and scalable secure automotive system across all ECU types.

The Motor Control Unit (MCU) and Vehicle Control Unit (VCU) are the backbone of an electric vehicle’s performance, ensuring seamless communication and precise control over various subsystems. While the MCU manages motor functions like speed, torque, and efficiency, the VCU oversees overall vehicle operations, integrating powertrain, battery, and safety mechanisms. Their synchronized operation enables optimal energy usage, smooth driving dynamics, and enhanced safety.

Trusted applications in automotive cybersecurity secure critical operations by isolating them. But how do they stay protected from the system they serve? Can a single line of code expose the entire chain of trust? Lets find out..
