AES_S2V_CMAC
Produces the synthetic initialization vector.
Syntax
IppStatus ippsAES_S2V_CMAC(const Ipp8u* pKey, int keyLen, const Ipp8u* AD[], const int ADlen[], int numAD, Ipp8u* pSIV);

ippcp.h
Parameters
pKey |
Pointer to the key. |
keyLen |
Length of the key in bytes. |
AD |
Array of pointers to individual input strings. |
ADlen |
Array of length (in bytes) of the individual input strings. |
numAD |
The number of the strings. |
pSIV |
Pointer to the output 16-byte vector. |
Description
The AES_S2V_CMAC function takes a key and maps the vector of individual strings AD[0], AD[1], …, AD[numAD-1] to the 16-byte output vector.
The function uses pseudorandom AES_CMACfunctions to process each input string, as well as doubling and xoringoperations to map the output toa single output vector.
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 or a pointer AD[i] to any individual string is NULL while the length ADlen[i] is non-zero. |
ippStsLengthErr |
Indicates an error condition that occurs because of one of the following:
