Secure MCU

There is an increasing demand on silicon manufacturers of microcontrollers (MCUs) to have security built into the hardware. The number of threat vectors to original equipment manufacturer (OEM) solutions based on MCU is increasing. To battle these threats the demand includes features for tamper detection, securing both RAM and flash memory, hardware features such as cryptographic accelerators and random number generators.

The Cypress PSoC 64 is a line of Secure Microcontrollers (MCUs) within the PSoC® 6 family that provides developers a secure framework for IoT applications. The PSoC® 64 MCU leverages the dual core architecture of the PSoC® 6 family establishing isolated processing environments between the 32-bit Arm® Cortex®-M4 Non-Secure Processing Environment (NSPE) for user application, as well as a 32-bit Cortex-M0+ core that acts as a coprocessing establishing a Secure Processing Environment (SPE). A secure enclave is further isolated from the SPE via a hardware-based Root-of-Trust (RoT) with trusted services. The trusted services utilize the RoT including cryptography engines, true random number generation (TRNG), and secure storage that provide secure boot, provisioning, and attestation capabilities to the MCU. The PSoC® 64 comes provided with the Trusted Firmware-M running in the secure environment which communicates to the non-secure Cortex-M4 through a hardware-based Inter-Processor interface (IPC) via API calls. PSoC® 64 Secure MCUs are certified as Level 1 compliant within the Arm Platform Security Architecture (PSA) certification scheme providing designers a robust, standards based secure MCU for IoT application and in addition, supports seamless integration with leading cloud providers such as Amazon Web Services (AWS) and Arm Pelion. Complete IoT security for node to cloud is enabled for developers with PSoC® 64 Secure MCUs.

When the inside of your home, office, or your wearable or medical devices are connected wirelessly, security is the top priority. Allowing access to data for those who are supposed to have it, while simultaneously protecting systems against attackers trying to modify the applications running by using methods of code injection like remote execution, is one of the key challenges in developing wireless microcontrollers. This is why the nRF5340 SoC offers the best and most recent security features from the Arm TrustZone technology. This MCU is the most advanced Bluetooth LE enabled microcontrollers to emerge from Nordic Semiconductor’s lineup so far. As the first of its kind the nRF5340 SoC is an all-in-one solution, featuring two separate Arm® Cortex™ M-33 processors with a multi-protocol radio. This gives it computing capabilities comparable to far more complex systems, but in a more compact package and with minimal power requirements. The built-in Arm TrustZone technology offers hardware implemented separation of secure and non-secure regions, applicable both to internal memory and peripherals. The MCU also features Arm CryptoCell-312 that offers stronger encryption than its predecessors, with 256-bit AES with GCM, and 3072-bit RSA. The CryptoCell-312 offers a root-of-trust for trusted execution through hardware, so no one can access the inner workings of your system unauthorized.

The nRF5340 has received the Platform Security Architecture (PSA) Certified™ Security Assurance Certificate, to PSA Certified Level 1.
