Abstract
The messages established on a communication path between two nodes are increasingly encrypted. However, the devices present on the communication path may intervene to transport the messages and to read, edit or add data in the messages. It may also be desirable that only “authorized” devices can carry out these actions. In order to intervene on these data, it would be necessary that the devices on the communication path have available all the keys used by the nodes to encrypt and decrypt the data of the messages, which is difficult to envisage. A modification method enables a device, capable of intercepting a data message on a communication path between two nodes, to edit the data under the control of the nodes, while ensuring that a device cannot access the data edited by another device on the path.
