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/
