int omac1_aes_128 ( const u8 key,
const u8 data,
size_t  data_len,
u8 mac 
)

omac1_aes_128 - One-Key CBC MAC (OMAC1) hash with AES-128 (aka AES-CMAC) : 128-bit key for the hash operation : Data buffer for which a MAC is determined : Length of data buffer in bytes : Buffer for MAC (128 bits, i.e., 16 bytes) Returns: 0 on success, -1 on failure

This is a mode for using block cipher (AES in this case) for authentication. OMAC1 was standardized with the name CMAC by NIST in a Special Publication (SP) 800-38B.

int omac1_aes_128_vector ( const u8 key,
size_t  num_elem,
const u8 addr[],
const size_t *  len,
u8 mac 
)

omac1_aes_128_vector - One-Key CBC MAC (OMAC1) hash with AES-128 : 128-bit key for the hash operation : Number of elements in the data vector : Pointers to the data areas : Lengths of the data blocks : Buffer for MAC (128 bits, i.e., 16 bytes) Returns: 0 on success, -1 on failure

This is a mode for using block cipher (AES in this case) for authentication. OMAC1 was standardized with the name CMAC by NIST in a Special Publication (SP) 800-38B.
