<p>A method for sending data from a second node (102) to a first node (100), including generating a hashed message authentication code (M) using a key and data, sending the hashed message authentication code (M) to the first node (100), generating a nonce in response to receiving the hashed message authentication code (M) by the first node (100), sending the nonce to the second node (102), sending the nonce, the key (K) and data (D) to the first node in response to the second node (102) receiving the nonce, verifying the hashed message authentication code (M) by the first node (100) using the key (K) and data (D), if the hashed message authentication code (M) is verified: generating a first representation on the first node (100) and a second representation on the second node (102), wherein the first representation and the second representation are associated with the key (K), and verifying that the first representation matches the second representation using an authentic channel (110).</p> |
