NXP® Semiconductors N.V. is one of the wolfSSL partner network members. wolfSSL ships with support for offloading cryptographic operations onto several NXP devices (such as the Coldfire and Kinetis) that include hardware cryptography modules. Examples of these operations include utilizing the Crypto Acceleration Unit (CAU), Memory-Mapped Crypto Acceleration Unit (mmCAU), LP Trusted Crypto (LTC), and more.
Using these hardware cryptography modules leads to increased performance when compared to performing hardware cryptography within software only. These speedups increase algorithm performance greatly, and can range from 1.2 times as fast to 14.5 times as fast! In an embedded and connected world, these speedups can make all the difference for an online device or network application. Additionally, these performance increases are available when wolfSSL is being used to manage TLS 1.3 connections, giving your embedded SSL/TLS application the ability to greatly increase performance and use the most up-to-date versions of the TLS protocol.
Benchmark numbers showing the comparison of hardware crypto vs. software crypto can be viewed on the wolfSSL benchmark page, here: https://www.wolfssl.com/docs/benchmarks/. This page also includes sample benchmark data for the NXP i.MX6, and the TWR-K70F120M devices. More benchmarks, and details about wolfSSL and NXP can be viewed on the wolfSSL website: https://www.wolfssl.com/docs/nxp/
More News on wolfSSL Support for NXP
wolfSSL develops a full suite of products supporting NXP designs. Learn about wolfBoot secure boot and TLS 1.3 firmware update with FreeRTOS and wolfSSL on NXP Freedom Board K64 here. And as with every release cycle, 4.2.0 improved support for crypto hardware performance, now on NXP mmCAU (download the latest wolfSSL version 4.5.0 here!)
wolfSSL also provisions surviving FIPS certificates that can be leveraged for your i.MX8, i.MX7 and i.MX8 CAAM projects. Stay tuned for upcoming FIPS 140-3 support. Also on the roadmap, upcoming support for NXP’s SE050 hardware security chip. This is an external I2C crypto co-processor chip that supports RSA key sizes up to 4096-bit, ECC curves up to 521 bit and ED25519/Curve25519. If your target is missing, tell us!
