Crypto Benchmark on STM32C0 MCU
ARM Cortex-M0+ @ 48 MHz

This benchmark conducted on NUCLEO-C092RC evaluation board with STM32C092RC MCU 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 STMicroelectronics STM32C0 microcontroller.
