This is information on a product in full production. May 2020 DS12737 Rev 4 1/339 STM32L552xx Ultra-low-power Arm ® Cortex®-M33 32-bit MCU+TrustZone®+FPU, 165 DMIPS, up to 512 KB Flash memory, 256 KB SRAM, SMPS

TrustZone technology for Arm Cortex-M processors enables robust levels of protection at all cost points for IoT devices. The technology reduces the potential for attack by isolating the critical security firmware, assets and private information from the rest of the application. of the Danish banking sector is protected by TRUSTZONE certificates Encrypt, Authenticate, Automate™ Apart from being Scandinavia’s largest vendor of SSL/TLS certificates, TRUSTZONE is a leading provider of scalable PKI and IoT solutions for encryption, authentication, and automated certificate lifecycle management. May 28, 2019 · The good thin is trustzone team advised me to acquire dedicated IP address at trust.zone. Dedicated IP is unique, no one uses it except me. Finally, got excellent Netflix quality and zero problems, no bans since feb 2018Use dedicated IP for netflix Jan 12, 2020 · TrustZone is the last hardware security mechanism integrated to ARMv8-M. This article presents some Fault Injection results achieved on Nuvoton M2351 (Cortex-M23), targeting MKROM crypto-functions and secure Code. ARMv8-M TrustZone. TrustZone technology (TZ) is NOT really a NEW security concept. It has been available on ARM Cortex-A since more TrustZone technology on the system infrastructure, the second looks at the impact of the technology to the ARM processor core, and the last part looks at the changes to the debug architecture. Chapter 4 TrustZone Hardware Library An overview of the TrustZ one-aware peripheral IP that is available from ARM. ARM TrustZone • ARM TrustZone is a hardware-software solution for security in handhelds – Important pieces of information such as various encryption keys must be protected – TrustZone hardware allows the application processor to execute in one of the three modes: normal, monitor, and secure The problem is the lack of secure storage, as TrustZone specification doesn’t provide any mechanism to implement secure storage. However, the TrustZone feature: assigning a specific peripheral to secure world access only is the key point, but it is up to the Soc Vendors or the TEE developers to decide what peripheral is used as a secure

With TrustZone, each DMA master and slave has access rights (like an MMU in a hypervisor). TrustZone is limited to either secure or normal. A secure peripheral can only be accessed by a secure master; a master is either a CPU or a device which does DMA. Some boot code must configure (and possibly lock) the slave and master permissions.

TrustZone + TEE techniques put the access control at the peripheral or memory and separate its management form system design and software not focused on security. This isolation barrier separates assets, giving two execution environments which prevail throughout the general assets of the SoC: ARM’s developer website includes documentation, tutorials, support resources and more. Over the next few months we will be adding more developer resources and documentation for all the products and technologies that ARM provides.

The APB4 TrustZone peripheral protection controller gates transactions to, and responses from, peripherals when a security violation occurs. The APB4 TrustZone peripheral protection controller can be instantiated in the system in connection to any non-security aware peripherals.
