1. A method of 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 second node having obtained a set of encryption variables from the first node, the method executed by the equipment capable of intercepting the data message, the method comprising:
intercepting 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;
extracting one encryption parameter, specific to the equipment intercepting the data message, from the encryption parameters obtained from the first node in the data message;
modifying at least one datum of the data message based on the extracted encryption parameter; and
sending the modified data message to the second node.
