AES_GCMProcessIV

Processes an initial vector of a given length according to the GCM specification.

Syntax

IppStatus ippsAES_GCMProcessIV(const Ipp8u*
pIV
, int
ivLen
, IppsAES_GCMState*
pState
);
Include Files
ippcp.h
Parameters
pIV
Pointer to the initialization vector.
ivLen
Length of the initialization vector
*pIV
(in bytes).
pState
Pointer to the
IppsAES_GCMState
context.
Description
The function processes
ivLen
bytes of the initial vector
*pIV
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 if the length of the initialization vector is zero.
ippStsBadArgErr
Indicates an error condition if the
pState
parameter value is not
GcmInit
or
GcmIVProcessing
. This means that the function call sequence is illegal.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
