49. Cryp_sm4_gmac

49.1. Function description:

This demo shows the operation of cryptographic processor, algorithm is SM4, algorithm mode including GMAC, appending data using the CPU in polling mode.

• Configure and prepare the authenticated data firstly, then start the authentication to get tag data.

• Compare the tag data with the standard to verify the function of authentication.

49.2. Test result:

After the operation done, if the tag data is same as the standard data, then print pass, if not print fail.
