STMicroelectronics has announced a major enabler for ubiquitous, best-in-class cybersecurity. ST’s STM32H7 high-performing MCUs are designed with the same security concepts as the PSA framework and combine these principles with STM32-familyenhanced security features and services.

 

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.

 

Commenting on the same, Michel Buffa, Microcontroller Division General Manager, STMicroelectronics, says, “Security is a major priority to ensure the success of the IoT. Winning the confidence of end-users from individual consumers to businesses and government agencies – is critical to adoption.” “PSA from Arm is making core security capabilities like device identity and over-the-air (OTA) updates more affordable and scalable for small autonomous IoT devices, and we’ve made it work with the existing security features of STM32 microcontrollers, including on our high-performing STM32H7 series.”

 

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. 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.

 

Speaking on behalf of Arm, Paul Williamson, Vice-President and General Manager, IoT Device IP, said, “Arm is working with our ecosystem to shift the economics of security with the introduction of PSA as a common industry framework for securing the next trillion connected devices.” “The secure hardware blocks and firmware-loading services ST has embedded in the Cortex-M based STM32H7 series utilizes the Arm PSA principles to drive innovation in security for a broad range of applications, including communication gateways and connected objects.”

 

The STM32H753 is in production now, priced at $8.90 for orders 10,000 pieces.
Other pricing options are also available.
