26.3. Equal symmetric encryption and decryption algorithm AES-CMAC

26.3.1. 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.

26.3.2. Board Setting

• No special settings

26.3.3. Running the example

When the project runs correctly, and the serial port terminal will output the following information:
