SH256 and SM3 Hash Algorithms

4.2.5

Verify that the hash calculation function of the secure OS is working properly.

See Test Networking.

1. The TrustZone kit has been burnt into the server and the TrustZone license has been activated.
2. The REE patch has been loaded to the server. The CA and TA can be loaded and can communicate with each other properly.

1. Log in to the REE OS and load the TrustZone REE patch tzdriver. (See Expected Result 1.)

   insmod tzdriver

   /usr/bin/teecd &

2. Write the CA and TA and make the following requirements on the CA and TA code. (See Expected Result 2.)
   • Test the digest calculation functions: TEE_DigestUpdate and TEE_DigestDoFinal.
   • Test the asymmetric key algorithms: SHA-256 and SM3.

1. The REE patch is loaded and no error information is displayed.
2. The APIs and algorithms are working properly.
