This is where ARM says PSA will come

Last year, ARM and SoftBank CEO Masayoshi Son predicted that the world could have a trillion connected devices by 2035. These devices will need protection not only at the network level, but also at the hardware level, to prevent them from being used for malicious purposes, as was the case with the Mirai botnet.

into play. The company, which estimates it will ship around 200 billion ARM-based chips by 2021, says security is no longer an optional feature for IoT, and hopes that PSA will reduce the impact of price factors and provide security from device manufacturing to the cloud.

The PSA framework is a recipe that covers the fundamentals of IoT security requirements. It includes threat models and security analysis, architectural specifications of hardware and its firmware, and also addresses firmware source code that allows for better implementation of IoT security standards.

In addition, PSA provides direction for implementing secure portugal whatsapp data for device identification and over-the-air updates with certificate-based authentication (instead of traditional password protection), as well as for implementing secure boot sequences.

This architecture is independent of operating systems and can be supported by ARM RTOS and products of the company's software partners, including ARM Mbed OS.

To encourage rapid adoption of PSA, the company also plans to promote an open-source firmware reference implementation called Trusted Firmware-M that supports the PSA specification. Its code will be released to the open source community in 2018, and until then, Trusted Firmware-M will target ARMv8-M systems.
