Renesas Electronics (tse:6723), a global semiconductor solution provider, announced today that the security engine of its 32-bit arm Cortex-M microcontroller (MCU) Ra product family has been certified by the National Institute of standards and Technology (NIST) encryption algorithm verification program (CAVP). The RA product family flexible configuration package (FSP) v3.6.0 and later will contain a certified sce9 protected mode driver.

Reza ra6m4, ra6m5, ra4m2 and ra4m3 MCU product groups have obtained NIST CAVP comprehensive encryption algorithm certification, including key generation and verification of multi-mode Advanced Encryption Standard (AES), hash algorithm, Rivest Shamir Adleman (RSA) and elliptic curve encryption (ECC), key protocol scheme and pseudo-random number generator (drbg). NIST CAVP certification provides independent verification of the correct implementation of encryption algorithms, which is essential to ensure interoperability of connections.

Last year, Renesas announced that RA series products have obtained PSA level 2 certification and Internet of things platform security assessment standard (sesip) certification at the same time.

Roger wendelken, senior vice president of Renesas’ electronic Internet of things and Infrastructure Division, said: “through CAVP certification, combined with the existing sesip1 and PSA level 2 certification, Renesas can provide a comprehensive Internet of things security solution. Users in the vast Internet application field can be confident in their data security in the applications implemented by using RA products.”

Renesas’ unique integrated security architecture provides a time-saving and energy-saving solution with unlimited security key storage capacity. A recently completed independent evaluation compared sce9’s protected mode operation with some of the industry’s leading safety components.

Mario Noseda of the school of engineering at the University of Applied Sciences in Zurich said, “sce9 not only has strong encryption computing power, but also gets rid of the serial interface with external connected devices (usually I2C) , which brings various advantages. The high-speed internal data bus greatly reduces the time required for data transmission between MCU and sce9, and more importantly, completely eliminates an attack point. This has also become a huge selling point of MCU including sce9. “

The management of encryption key is very important to maintain the integrity of security products. The new security key management tool provides a direct mechanism for preparing keys for security installation and security update, and supports the development, production configuration and key update of on-site products. Its GUI interface is designed to help developers (especially those who are new to security solutions) create prototypes and proof of concept using test keys. The command line interface can coordinate multiple developers and support the configuration and update management of production keys. The downloadable application project demonstrates how to use existing Renesas tools to perform security key installation and update for development and production.

In addition to the widely recognized industry certification, Renesas RA MCU also creates advanced Internet of things security for users by combining the arm TrustZone of armv8-m with the security encryption engine certified by NIST CAVP. RA product family integrates hardware based security functions, including a fully integrated encryption subsystem from simple AES acceleration to isolation in MCU. The security encryption engine provides symmetric and asymmetric encryption / decryption, hash function, true random number generator (TRNG) and advanced key management functions, including key generation function and MCU hardware related unique key encapsulation function. If the correct access protocol is not followed, the access management circuit will shut down the encryption engine, and the built-in dedicated RAM can ensure that the plaintext key will never be exposed to any CPU or peripheral bus.

About Renesas RA MCU

RA product family ecosystem accelerates the development of Internet of things applications through core technologies such as network security, functional security, connectivity and HMI (human machine interface). Engineers can easily develop Internet of things endpoints and edge devices by using RA MCU for design, and can be used in industrial and building automation, metrology, medical care, home appliances and other applications. The RA product family includes ra2 series (up to 48mhz), RA4 series (up to 100MHz), RA6 series (up to 240mhz) and the upcoming single core / dual core ra8 series.
