AES_GCMProcessAAD
AES_GCMProcessAAD
Processes additional authenticated data of a given length according to the GCM specification.
Syntax
IppStatus ippsAES_GCMProcessAAD(const Ipp8u*
pAAD
, int
ivAAD
, IppsAES_GCMState*
pState
);
Include Files
ippcp.h
Parameters
- pAAD
- Pointer to the additional authenticated data.
- ivAAD
- Length of additional authenticated data*pAAD(in bytes).
- pState
- Pointer to theIppsAES_GCMStatecontext.
Description
The function processes
ivAAD
bytes of additional authenticated data *pAAD
as specified in [NIST SP 800-38D]. Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or warning.
- ippStsNullPtrErr
- Indicates an error condition if any of the specified pointers is NULL.
- ippStsContextMatchErr
- Indicates an error condition if the context parameter does not match the operation.
- ippStsLengthErr
- Indicates an error condition ifivAADis less than zero.
- ippStsBadArgErr
- Indicates an error condition ifivAADis zero andpStateis notGcmInitorGcmIVProcessing. This means that the function call sequence is illegal.
