emberAfPluginAesMacAuthenticate#

void emberAfPluginAesMacAuthenticate (const uint8_t * key, const uint8_t * message, uint8_t messageLength, uint8_t * out)

Compute the Cipher-based Message Authentication Code (CMAC) corresponding to the passed message and the passed key.

Parameters
[in]key

The key to be used to produce the cipher-based authentication code.

[in]message

A pointer to the message for which a cipher-based authentication code should be computed.

[in]messageLength

The length in bytes of the message to be authenticated.

[out]out

A pointer to a 16-byte area memory in which the resulting cipher-based authentication code will be stored.
