Abstract: The invention relates to a device for monitoring physical objects that comprises one or more short-range remote readers, memory elements to be attached to physical objects, and a controller adapted for executing a reading function capable of interaction with the one or more remote readers in order to acquire data contained in adjacent memory elements, and for executing an integrity validation function capable of distinguishing, from the acquired data, individual identifiers particular to each of the memory elements as well as group description data stored in at least some of said memory elements, and of checking the sufficiency of group description data while checking the compliance of individual identifiers with corresponding group description data.

Abstract: A method of switching a mobile terminal from a first access router to a second access router, the terminal having previously set up a secure connection with the first access router with which is associated a communication context between the terminal and the first router, said context comprising at least one identifier relating to a set of security parameters of the connection. The invention relates to a method wherein said context is transferred to the second router while the terminal is switching, the method comprising, if the at least one identifier in the transferred context is already being used by said second router, a step of the second router sending the terminal a new identifier for said set of security parameters.
