ARM introduced TrustZone to the Cortex-M series of microcontrollers with the ARMv8-M architecture. TrustZone is an optional security extension that enables two security domains within a single processor. Cortex-M cores (including the Cortex-M33 and Cortex-M23) that include TrustZone use […]

Nov 10, 2015 · ARM is bringing the Trustzone security architecture to future Cortex-M processor cores, combining that with a version of the ARM hardware bus (AHB) that will recognise the difference between secure and non-secure transactions. ARM7TDMI 시절에는 예외 상황이 Thumb 모드에서 직접 처리되지 않고 ARM 모드로 전환해야만 했지만 Thumb-2에서는 Thumb 모드에서 예외 처리가 가능하게 되었다. 사실 이 특징으로 인해 Cortex-M 계열이 Thumb 명령어만 사용 가능한 제품군으로 분리하는 게 가능해진 것. Using TrustZone for ARMv8-M on ARM Cortex-M23 and Bringing TrustZone to the Cortex-M family High performance Performance efficiency Lowest power & area In collaboration with interested parties, we will continue to enhance TF-A with reference implementations of Arm standards to benefit developers working with Armv7-A and Armv8-A TrustZone technology. Users are encouraged to do their own security validation, including penetration testing, on any secure world code derived from TF-A. Oct 26, 2016 · ARM launched its first Cortex-M MCUs with ARMv8-M and TrustZone security: the tiny, low-power Cortex-M23 and faster Cortex-M33. At the ARM TechCon show in Santa Clara, ARM unveiled two new Cortex-M microprocessors that will likely emerge as major Internet of Things workhorses over the coming decade, supplanting most existing Cortex-M designs. Oct 25, 2016 · ARM ports Trustzone down to Cortex-M IoT ecosystems should shift to cellular connectivity for security – report ARM has launched the first of a series of Cortex-M series microcontrollers based on the V8M architecture that incorporate the Trustzone security mechanism. Sep 23, 2019 · • The Cortex-M55 processor, Arm's most AI-capable Cortex-M processor • The Ethos-U55, the industry's first micro neural microprocessor (microNPU) that's designed to work with Cortex-M processors. These technologies can be developed in a unified software toolchain for the simplest and fastest development path for AI.

ARM introduces first Cortex-M cores with Trustzone

TrustZone for Armv8-M (for Cortex-M profile) The Security Extension, marketed as TrustZone for Armv8-M Technology, was introduced in the Armv8-M architecture. No-execute page protection. As of Armv6, the Arm architecture supports no-execute page protection, which is referred to as XN, for eXecute Never. Arm TrustZone technology is a system-on-chip (SoC) and CPU system-wide approach to security with hardware-enforced isolation to establish secure end points and a device root of trust. TrustZone for Cortex-A Processors TrustZone for Cortex-M Processors TrustZone Security System IP Arm Microcontroller Security with TrustZone-M Standard Level - 2 days view dates and locations. With the ever increasing range of applications for Arm® microcontrollers, from simple environmental monitors, through to automotive components and complex consumer appliances, the issue of security when developing these devices has never been so crucial. Oct 10, 2018 · This is one of the first Cortex-M processors with Arm TrustZone security technology, bringing a new level of trust to embedded systems. These new NXP microcontroller families represent the next generation of Cortex-M based design, familiar to thousands of developers and used in millions of designs. What was released by NXP?

Securing the edge with ARM TrustZone for v8-M

Introducing ARM Cortex-M23 and Cortex-M33 Processors with The Cortex-M23 and Cortex-M33 processors are the newest members of the highly popular Cortex-M product family. As such, the two processors maintain the expected characteristics of the embbeded profile such as real-time deterministic interrupt response, low power, low area, ease of development, and 32-bit performance. The security foundation is introduced via the addition of TrustZone® technology.
