Arm Platform Security Architecture (PSA) uses cost-effective, leading-edge technology to comprehensively enhance security technology support for the IoT market Arm Cortex-M7 microcontrollers developed based on the STM32H7 series integrate PSA concepts and advanced security functions services

China, October 23, 2017 ---- A global semiconductor leader across multiple electronics applications, the world's leading Arm microcontroller manufacturer for Internet of Things (IoT) devicesSTMicroelectronics (STMicroelectronics, NYSE: STM), today launched the Platform Security Architecture (PSA). PSA is a key technology for achieving best-in-class pervasive network security. ST's STM32H7 high-performance microcontrollers adopt the same security concepts as the PSA framework and perfectly combine these concepts with the enhanced security features and services of the STM32 product family. Individual users and organizations increasingly rely on connected electronic products to manage time, monitor health, handle social activities, enjoy or provide services, and improve work efficiency. Preventing unauthorized interactions with devices is extremely important for protecting device identities, personal information, physical assets, and intellectual property. As the scale and popularity of the Internet of Things increase, both citizen safety and national security are threatened. Device manufacturers must continue to innovate security systems to combat the endless intrusion methods of hackers. PSA enables them to implement the most advanced security mechanisms on small devices with limited resources at an appropriate cost. “Ensuring the success of the Internet of Things requires security first,” said Michel Buffa, General Manager, Microcontroller Division, STMicroelectronics. “Winning the trust of all end users, from individual consumers to enterprises and governments, is critical to the widespread adoption of the Internet of Things. Arm’s PSA platform makes core security functions of autonomous IoT devices, such as device identification and over-the-air (OTA) software updates, more affordable and scalable. We have integrated it into the STM32 microcontroller family, including the STM32H7 High Performance series, to work in conjunction with existing security features.” MCUs integrate hardware security features such as hardware random number generators (TRNG) and advanced cryptographic processors to simplify the security design of embedded applications and global IoT systems, and prevent network attacks such as network eavesdropping, deception, or man-in-the-middle intervention. In addition, the secure firmware loading function helps OEMs ensure that product programming is safe and reliable, and firmware can be safely loaded into product devices even in non-internal production environments such as foundries or program development companies. To achieve the secure loading function, the security keys and software services pre-installed in the microcontroller allow OEMs to hand over encrypted firmware to the foundry, eliminating the possibility of intercepting, copying, or tampering with the firmware with code. This can realize the function of writing code to the device and verifying the device, and establish the trusted root mechanism required for the device to connect to the end-user network to complete remote over-the-air updates (OTA), so as to download and install security patches or upgrade software during the life cycle of the device. “With the introduction of the PSA Platform Security Architecture, a common industrial framework to secure trillions of IoT devices in the future, Arm is revolutionizing the economics of security technology with the ecosystem,” said Paul Williamson, vice president and general manager of the IoT IP business group at Arm. “ST has embedded a hardware security module and firmware loading services in the STM32H7 Cortex-M microcontrollers, leveraging Arm’s PSA concepts to drive security technology innovation in application areas such as communication gateways and IoT devices.” Note: As a member of the STM32H7 series that supports PSA, the STM32H753 The MCU is based on Arm's highest-performance embedded processor core (Cortex-M7), which sets a new industry record for processing performance when executing embedded flash code at a frequency of 400MHz, with a test score of 2020 CoreMark/856 DMIPS. To further improve the performance of the microcontroller, STMicroelectronics has also implemented other innovative technical features on the chip, including Chrom-ART Accelerator for faster and more efficient graphical user interface processing, hardware JPEG codec for high-speed image processing, efficient direct memory access (DMA) controller, on-chip dual-zone Flash with a maximum capacity of 2MB of simultaneous read and write, and L1 cache that allows the microcontroller to access off-chip memory at full speed. Multiple power domains allow developers to minimize application power consumption, while a sufficient number of I/O ports, communication interfaces, audio and analog peripherals meet the needs of applications such as entertainment, remote monitoring and control. The STM32H753 is in mass production now.

The key is the price. NXP seems to be relatively lower than ST.
