MCU Enlists ARM Security Architecture

STMicroelectronics employs the Platform Security Architecture (PSA) from ARM in its STM32H7 MCUs. As the IoT grows in scope and pervasiveness, public safety and national security are also at stake. As device manufacturers must always innovate to beat new and inventive hacking exploits, PSA helps them implement state-of-the-art security cost-effectively in small, resource-constrained devices.

 

ST’s STM32H7 MCU devices integrate hardware-based security features including a True Random-Number Generator (TRNG) and advanced cryptographic processor, which will simplify protecting embedded applications and global IoT systems against attacks like eavesdropping, spoofing, or man-in-the-middle interception. In addition, secure firmware loading facilities help OEMs ensure their products can be programmed safely and securely, even off-site at a contract manufacturer or programming house.

SENSORS MIDWEST

Sensors Midwest Hits Rosemont, IL October 16-17!

Sensors Midwest, the industry's largest event focusing on sensors, design, and IIoT in the Midwest region, is scheduled for October 16-17 at the Donald E. Stephens Convention Center in Rosemont, IL. Co-located with STMA, the event draws over 1,000 engineers and engineering professionals that are looking for access to the latest sensor advancements and will provide an opportunity to connect with the area's greatest technology leaders and suppliers.

 

To enable secure loading, security keys and software services already on-board the MCU permit OEMs to provide manufacturing partners with already-encrypted firmware, making intercepting, copying, or tampering with the code impossible. This enables programming and authenticating the device to establish the root-of-trust mechanism needed for the device to be connected to the end-user’s network and remotely updated over the air (OTA) to apply security patches or feature upgrades throughout the lifetime of the device.

 

The STM32H753 is in production now, priced $8.90 each/10,000 pieces. Other pricing options are available. For more details, a datasheet is available.
