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 an mbed TLS glue layer to enable both hardware-accelerated and software-based mbed TLS implementation at the same time.

Note

The nrf_security module interfaces with the nrf_cc3xx_mbedcrypto library. This library conforms to a specific version of mbed TLS.
