Abstract: A method for securing data flows in a communication device configurable from a remote terminal, the method comprising steps of recording a first encryption key in a memory of the device, the generation, from the first key, of a public key and of a private key corresponding to the public key, the reception of a request for securing sent by the remote terminal and a sending of the public key to the remote terminal in response to the request for securing, the operations of receiving the request and of sending the public key being performed when the device and the terminal are connected to the same local network. Another object of the invention is a communication device configured to implement the method described.

Abstract: In order to control a measuring system with a tacheometer mounted on a carrier trolley circulating on a railway track under construction and a target fastened to a railway construction machine, the carrier trolley is circulated on the railway track in a working direction from a starting position to an arrival position in the vicinity of a topographic arrival singularity. The carrier trolley is immobilized and an observation of the topographic arrival singularity is made. Then, with the railway construction machine having been brought into the starting position, an observation of the target is made. Finally, the coordinates of the arrival position of the carrier trolley are calculated as a function of the measurements made, of additional data relating to the starting position, and of positioning data of the topographic arrival singularity and data relating to a theoretical line of the track.

Abstract: A gateway manages a first secure wireless local network and a second secure wireless local network. The gateway interconnects the second secure wireless local network and a wide-area network so that each device paired with the second secure wireless local network can access services offered by the wide-area network. The gateway detects an attempt at first pairing, with the first secure wireless local network, using first authentication data. The gateway checks with a provisioning server that the first pairing is performed by a device associated with the same user as the gateway, and checks that the first authentication data correspond to expected authentication data. In the case of a positive check, the gateway transmits, via the first secure wireless local network, second authentication data as well as a network identifier of the second secure wireless local network, with a view to pairing with the second secure wireless local network.

Abstract: Some embodiments of the present application relate to the field of gateways for internet access, associated video service decoders and the methods for broadcasting video content by an operator through such a gateway intended for such a decoder. A virtual MAC address is dedicated to VOD on the decoder. This address is then recognized by the gateway. The gateway implements a direct circuit directly directing the traffic related to this virtual address between the interface for accessing the communications network and the gateway physical port to which the decoder is connected. Advantageously, the circuit is dynamically configured by intercepting the DHCP request used to configure this virtual address.
