Nordic Security Module

The Nordic Security Module (nrf_security) provides an integration between Mbed TLS and software libraries that provide hardware-accelerated cryptographic functionality on selected Nordic Semiconductor SoCs as well as alternate software-based implementations of the Mbed TLS APIs. This module includes a PSA driver abstraction layer to enable both hardware-accelerated and software-based implementation at the same time.

The nrf_security module can interface with the nrf_cc3xx_mbedcrypto library. This library conforms to the specific revision of Mbed TLS that is supplied through the nRF Connect SDK.
