With the introduction of the connected car, secure transfer of data to and from the vehicle is critical for safe and reliable operation. Gateway modules serve as the gate keeper between the Internet and the a car's internal network. The gateway module's central microcontroller needs to have robust on-chip security capabilities to help serve this function. The gateway microcontroller in this demo, the MPC5748G, includes an embedded hardware security engine -- the Hardware Security Module (HSM).


This security demo utilizes the on-chip HSM to decrypt images captured live and securely, through AES encryption, and transmitted via Wi-Fi.
