Internet connectivity will bring a multitude of services to vehicles and their owners, such as software updates, service packs, location-based information, social media, streaming entertainment content and emergency support. This brings forth the need to protect connected cars against internet-based attacks that can steal personal data or compromise important vehicle systems.

STMicroelectronics’ secure microcontrollers (ST32G512A and ST33G1M2A) are qualified to the stringent automotive quality standard AEC-Q100. In the connected car, the secure microcontroller handles authentication in a similar way to a smartphone’s SIM. Additional security implemented by unalterable hardware in the ST33G1M2A allows use as an embedded secure element that provides a root of trust for preventing attacks on vehicle engine control units (ECUs) and gateways. The ST33 family is already useful in applications such as NFC SIM and NFC embedded secure element.

In addition to connected car applications, the secure MCUs are suitable for a variety of M2M communications in harsh environments, such as industrial networking and asset monitoring. Engineers can port software already qualified on compatible previous-generation devices (ST32/ST33) to streamline development and reduce time to market.
