Avnet / WNCInterface

The WDCInterface is is a drop-in replacement for an EthernetInterface class that allows the user to connect to the Internet with a Wistron NeWeb Corporation (WNC) M14A2A Series data module using the standard network Socket API's. This interface class is used in the AT&T Cellular IoT Starter Kit which is sold by Avnet (http://cloudconnectkits.org/product/att-cellular-iot-starter-kit).

Function Documentation

int mbedtls_aesni_crypt_ecb ( mbedtls_aes_context *  ctx,
int  mode,
const unsigned char  input[16],
unsigned char  output[16] 
)

AES-NI AES-ECB block en(de)cryption.

Parameters:
ctxAES context
modeMBEDTLS_AES_ENCRYPT or MBEDTLS_AES_DECRYPT
input16-byte input block
output16-byte output block
Returns:
0 on success (cannot fail)

Definition at line 95 of file aesni.c.

void mbedtls_aesni_gcm_mult ( unsigned char  c[16],
const unsigned char  a[16],
const unsigned char  b[16] 
)

GCM multiplication: c = a * b in GF(2^128)

Parameters:
cResult
aFirst operand
bSecond operand
Note:
Both operands and result are bit strings interpreted as elements of GF(2^128) as per the GCM spec.

Definition at line 141 of file aesni.c.

int mbedtls_aesni_has_support ( unsigned int  what )

AES-NI features detection routine.

Parameters:
whatThe feature to detect (MBEDTLS_AESNI_AES or MBEDTLS_AESNI_CLMUL)
Returns:
1 if CPU has support for the feature, 0 otherwise

Definition at line 48 of file aesni.c.

void mbedtls_aesni_inverse_key ( unsigned char *  invkey,
const unsigned char *  fwdkey,
int  nr 
)

Compute decryption round keys from encryption round keys.

Parameters:
invkeyRound keys for the equivalent inverse cipher
fwdkeyOriginal round keys (for encryption)
nrNumber of rounds (that is, number of round keys minus one)

Definition at line 252 of file aesni.c.

int mbedtls_aesni_setkey_enc ( unsigned char *  rk,
const unsigned char *  key,
size_t  bits 
)

Perform key expansion (for encryption)

Parameters:
rkDestination buffer where the round keys are written
keyEncryption key
bitsKey size in bits (must be 128, 192 or 256)
Returns:
0 if successful, or MBEDTLS_ERR_AES_INVALID_KEY_LENGTH
