Crypto Benchmark on MCX E31B MCU
ARM Cortex-M7 @ 160 MHz

This benchmark conducted on FRDM-MCXE31B Development Board for MCX E31 MCUs will help you in qualifying performance of CycloneCRYPTO (Cryptography library), CycloneSSL (TLS 1.3 & DTLS 1.2 library), CycloneSSH (SSH library with SCP & SFTP protocols), CycloneIPSEC (IPsec/IKEv2 library) and CycloneTCP (TCP/IPv4/IPv6 stack with secure protocols like HTTPS, FTPS, MQTTS, Secure WebSocket, Secure CoAP, Secure Modbus/TCP, SNMPv3...) running on NXP MCX E31B microcontroller.
