For transporting packets between an access interface of a subscriber installation and a concentrating router of a shared network the access interface carries out control operations on streams of packets transmitted to the concentrating router, within the framework of a contract between the subscriber and a manager of the shared network. After having carried out the control operations concerning a packet to be transmitted, the access interface transmits this packet to the concentrating router with a signature based on a secret shared with the concentrating router, authenticating that the packet has been subjected to the control operations.
