22.3. Equal symmetric encryption and decryption algorithm AES-CMAC¶
22.3.1. 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.
22.3.2. Board Setting¶
No special settings
22.3.3. Running the example¶
When the project runs correctly, and the serial port terminal will output the following information:
> tc_start() - Performing CMAC tests:
> Performing CMAC test #1 (GF(2^128) double):
> ===================================================================
> PASS - verify_gf_2_128_double.
> Performing CMAC test #2 (SP 800-38B test vector #1):
> ===================================================================
