Abstract: The invention relates to a method for processing, by a computer system (100) installed on board a motor vehicle, a signal transmitted by a remote communicating entity and received by means of a radiofrequency signal communication apparatus arranged inside the vehicle, and to a system implementing such a method and to a motor vehicle comprising such a system. The aim of the invention is to determine the plausibility of a radiofrequency signal transmitted by a remote communicating entity, in particular a signal that contains data relative to a followed course and/or a geographical position of the vehicle.

Abstract: A method of managing a communication network comprising a control plane and a network plane, the network comprising nodes and physical connections of the nodes, each of a plurality of nodes being a logical network device, supporting a control plane portion in the control plane and a network plane portion in the network plane, in which method, the control plane portions of the logical network devices form a logical network in a peer to peer fashion, and control data necessary for administering the communication network and/or for managing users of the communication network is contained in at least one database distributed between at least a plurality of control plane portions of the network devices forming the logical network.
