The AES-GCM core has a 32-bit word-based data interface with support for a 256-bit key. The AES-GCM mode supports encryption and decryption, multiple key sources, and built-in message integrity check.

Note:   The AES engine operates on a 32-bit boundary.

The AES-GCM-256 core allows for the following key sources.

BBRAM key

eFUSE device key

Operation key (OPKEY)

Key update register (KUP)

Family key (for obfuscated key storage)

PUF key-encryption-key (KEK) (for black key storage)
