Detailed Description

Args for GMAC generate and verify Note: These services are only available in HSSE mode.

Generate: on return ptrTag holds the full 16-byte GMAC output. Verify: ptrTag must contain the expected 16-byte tag. ACK if tags match, NACK otherwise.

Parameters

ptrData	Pointer to input data in shared memory
dataLen	Length of input data in bytes
ptrTag	Pointer to 16-byte tag buffer
ptrIV	Pointer to IV buffer
ivLen	Length of IV in bytes

Data Fields
uint8_t *	ptrData
