ST: STM32H7 series leverages new platform security architecture from Arm

STMicroelectronics welcomes Platform Security Architecture (PSA) from Arm as a major enabler for ubiquitous, best-in-class cyber security. ST’s STM32H7 high-performing MCUs are designed with the same security concepts as the PSA framework and combine these principles with STM32-family enhanced security features and services.

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.
