Classification: CPC H | IPC H

Claim 9:
10. A device for modifying a data message sent by a first node to a second node on a path of a communication network comprising an equipment capable of intercepting the data message, the path established between the two nodes, the second node having previously obtained a set of encryption variables from the first node, the device comprising a processor and a memory, the device configured to:
intercept the data message sent from the first node and destined for the second node, the data message comprising encryption parameters relating to the set of encryption variables;
extract one encryption parameter, specific to the equipment intercepting the message, from the encryption parameters received from the first node in the data message;
modify at least one datum in the data message based on the extracted encryption parameter; and
send the modified data message to the second node.
