TLS is the global standard for secure Internet communications. A TLS solution based on integrated and certified hardware security engines such as Renesas TSIP (Trusted Secure IP) and SCE (Secure Crypto Engine) provides the ultimate mechanism to create secure IoT products. The wolfSSL Integrated TLS Stack is a lightweight TLS solution written in ANSI C and intended for embedded, RTOS, and resource-constrained environments primarily due to its small size, speed, and feature set. wolfSSL supports industry standards up to 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 lightweight wolfCrypt encryption library, which has been FIPS 140-2 Level 1 certified. WolfCrypt supports the most popular algorithms and ciphers as well. than the more progressive ones such as quantum key exchange available through the liboqs of the Open Quantum Safe project.

Security is a key differentiator for MCU customers, especially in the rapidly growing IoT market, and Renesas has established leadership in security with a wide range of solutions and certifications. Earlier this year, Renesas announced the FIPS 140-2 Level 3 certification of the RX65N, the first such certification for a general-purpose MCU. Family Arm® Cortex-M RA microcontrollers have achieved 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 side channel attacks and SPA / DPA on encryption operations. All families offer devices with unlimited secure key storage, with the RA family offering simplified secure key installation.

“As a leader in MCUs, we pride ourselves on delivering added value to our customers,” said Roger Wendelken, senior vice president of the IoT and Infrastructure business unit at Renesas. “In addition to the many security features built into our products, the free offering of wolfSSL TLS commercial licenses and high quality cryptographic software is a clear example of this philosophy. “

“Renesas shares our passion for security,” said Larry Stefonic, CEO of wolfSSL. “We are delighted that Renesas MCU’s very large customer base now has easy and unhindered access to our industry-leading crypto software to implement the best and most up-to-date security. Renesas empowers clients to do more with less effort; isn’t that what the best MCU vendors should be doing? “
