Designing Secure IoT devices with the Arm Platform Security Architecture and Cortex-M33 explains how to design and deploy secure IoT devices based on the Cortex-M23/M33 processor. The book is split into three parts. First, it introduces the Cortex-M33 and its architectural design and major processor peripherals. Second, it shows how to design secure software and secure communications to minimize the threat of both hardware and software hacking. And finally, it examines common IoT cloud systems and how to design and deploy a fleet of IoT devices. Example projects are provided for the Keil MDK-ARM and NXP LPCXpresso tool chains. 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 the features necessary to create both a secure and functional device. The recent development by ARM of the Cortex M23 and M33 architecture is intended for today's IoT world.

About the author
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.
