tegra_se.h File Reference

Detailed Description

AES-256 hardware key definition functions

Description: This file specifies AES-256 hardware key definition functions.

There are two groups of functions:

• Hardware-based AES-CMAC functions, for use only at boot time
• NIST-SP 800-108 key definition functions, for use (with the respective function) at either boot time or run time.

Definition in file tegra_se.h.
