# Equal symmetric encryption and decryption algorithm AES-CMAC

## Overview

**aes_cmac_mode_example** the example project shows the implementation of aes-cmac mode of equal symmetric encryption and decryption algorithm.
- The equal symmetry encryption and decryption algorithm of this project adopts aes-cmac mode, and the integrity verification of encryption and decryption information of cmak module is completed through 5 tests.

## Board Setting

- No special settings

## Running the example

When the project runs correctly, and the serial port terminal will output the following information:
```console
tc_start() - Performing CMAC tests:
