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 mapsthe vector of individual strings AD[0], AD[1], …, AD[numAD-1] tothe 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:
