NXP’s LPC55S6x MCUs are dual-core Arm Cortex-M33 MCUs, which leverage the Armv8-M architecture to deliver advanced security capabilities. One of the cores includes Arm TrustZone technology and a memory protection Unit.
The MCU is equipped with crypto accelerators for symmetric and asymmetric cryptography and a PUF (Physically Unclonable Function) to fight cloning and counterfeiting. It has a True Random Number Generator (TRNG), a Unique Device Identifier, Secure GPIOs, secure authenticate debug capabilities, a secure boot with root-of-trust keys and anti-rollback protection, real-time PRINCE encryption/decryption of the on-chip flash and it supports the Device Identification Composition Engine (DICE) as specified by the TCG (Trusted Computing Group).
C-Trust is as an extension of the complete development toolchain IAR Embedded Workbench for Arm and enables developers to protect an existing or new application, and ease mastering the deeper complexities of security, through the use of Security Context Profiles. These Security Context Profiles are developed by Secure Thingz, an expert in device security, and include all the necessary security and encryption settings, such as cryptographic keys and certificates, Secure Boot Manager configuration, access to platform security features, application update process and policy, and device memory layout. C-Trust provides the application with a robust protection against Intellectual Property (IP) theft, malware injection, counterfeiting and overproduction. This technology takes advantage of the hardware security features of Arm TrustZone technology to protect both the included Secure Boot Manager and the cryptographic keys needed to protect software IP.
IAR Systems and Secure Thingz also offer the Security from Inception Suite which is a unique set of tools and services for implementing and customising security in embedded applications. To enable secure transferring of designs into production, the Security from Inception Suite includes Secure Desktop Provisioner which delivers improvements on the ease of implementation of security across the supply chain. The entire offering supports many mainstream devices as well as devices secured by Arm TrustZone technology, such as the NXP LPC55S6x MCUs.
“The support of NXP’s LPC55S6x Arm Cortex-M33 MCUs in our security offering adds extended possibilities for the joint customers of IAR Systems and NXP,” said Clive Watts, Security Products Manager at Secure Thingz/IAR Systems. “With the right tools, you can translate your security design in a reliable implementation leveraging the right security features of the selected MCUs, and we will continue to leverage our strong industry relationships to expand our device support and help organizations both in creating new secure applications easier as well as implementing security in existing applications.”
