Designing Secure IoT Devices with the Arm Platform Security Architecture and Cortex-M33 - Tapa blanda

Trevor Martin graduated from Brunel University in 1988 with an Honors degree in electrical and electronics engineering. In the same year, he began work as a junior hardware engineer at Philips Medical Systems. He joined Hitex in 1992 as a technical specialist for 8-bit microcontroller development tools. This included the 8051,68HC11\05\08 microcontrollers. He also gained experience with networking protocols such as CAN, USB, and TCP/IP. Since 2000, he has been supporting ARM-based microcontrollers, initially ARM7 and ARM9 CPU then moving to Cortex-M processor. To promote these devices, he has worked closely with both NXP and ST and also TI and Freescale to a lesser extent. Since 2005, he has written a number of “Insider’s Guide” books that are introductory tutorials to ARM-based microcontroller families such as LPC2000, STR9, and STM32. He also runs regular training courses, a general Cortex Microcontroller workshop and also device-specific courses.

De la contraportada

Since their inception, microcontrollers have been designed as functional devices with a CPU, memory, and peripherals that can be programmed to accomplish a huge range of tasks. With the growth of internet-connected devices and the Internet of Things (IoT), "plain old microcontrollers" are no longer suitable as they lack many features that are necessary to create both a secure and functional device. The recent development by Arm of the Armv8-M architecture has created a processor family that meets the needs of today’s IoT world.

explains how to design and deploy secure IoT devices based on the Cortex-M33 processor and the TrustZone security peripheral using the Arm Platform Security Architecture (PSA). The book is split into three parts. First, it introduces the Cortex-M33, its architectural design, and major processor peripherals including the TrustZone Security peripheral. Second, it provides an introduction to modern cryptography for developers of microcontroller-based systems. Third, it introduces the PSA Security Model and Trusted Firmware to create IoT devices that are resistant to both network and software attacks.

This book is designed as a hands-on tutorial with example code that can be ported to Cortex-M33-based microcontrollers. Example projects are provided for the Keil MDK-ARM community edition toolchain and the NXP LPC55S69 microcontroller.
