Renesas, WolfSSL team for free embedded IoT security license
All Renesas 32bit RA, RX and Synergy microcontrollers can access a free wolfSSL standard commercial license to use the wolfCrypt cryptographic library

Renesas Electronics and wolfSSL have signed a multi-year licensing agreement to provide a free commercial license to IoT security technology across the range of different Renesas 32bit microcontrollers.

Developers using either the ARM-based RA family or Renesas RX core devices can obtain a free commercial license for the wolfSSL TLS (Transport Layer Security) stack with integrated Renesas hardware security engine support plus the FIPS certified wolfCrypt crypto library. All customers of Renesas RA Family, RX Family, and Synergy Platform MCUs are eligible for the commercial license, which includes technical support from wolfSSL.

TLS is the world-wide standard for securing internet communications. A TLS solution built on certified, integrated hardware security engines such as the Renesas TSIP (Trusted Secure IP) and SCE (Secure Crypto Engine) provides the ultimate mechanism to create secure IoT products.

The wolfSSL embedded TLS stack is a lightweight TLS solution written in ANSI C and targeted for embedded, RTOS, and resource-constrained environments - primarily because of its small size, speed, and feature set. wolfSSL supports industry standards up to the current TLS 1.3 and DTLS 1.2 levels, and is up to 20 times smaller than OpenSSL.

In addition to full integration with the Renesas MCU’s hardware security engines, wolfSSL includes the wolfCrypt lightweight crypto library, which has been certified to FIPS 140-2 Level 1. wolfCrypt supports the most popular algorithms and ciphers as well as progressive ones such as post-quantum key exchange available through available through the Open Quantum Safe project's liboqs.

Security is a key issue for microcontroller customers, particularly in the fast-growing IoT market. Earlier this year, Renesas announced FIPS 140-2 Level 3 certification of the RX65N, the first such certification for a general purpose MCU. RA Family Arm Cortex-M MCUs have achieved both PSA Certified Level 2 and Security Evaluation Standard for IoT Platforms (SESIP) certifications, with additional NIST certifications planned. Renesas offers MCU devices with protections against timing and SPA/DPA side-channel attacks on crypto operations. All families offer devices with unlimited secure key storage, with the RA Family offering simplified secure key installation.

“As the MCU leader, we pride ourselves in delivering added value to our customers,” said Roger Wendelken, Senior Vice President in Renesas’ IoT and Infrastructure Business Unit. “In addition to the many security features built into our products, offering high-quality wolfSSL TLS and crypto software commercial licenses free of charge is a clear example of that philosophy.”

“Renesas shares our passion for security,” said wolfSSL CEO, Larry Stefonic. “We’re pleased that the very large Renesas MCU customer base will now have easy and unfettered access to our market leading cryptography software to implement the best, most up-to-date security."

Renesas 32-bit MCU customers can download the wolfSSL TLS stack, including the wolfCrypt Cryptography library today at https://github.com/wolfssl/Renesas.
