A method for activating an operational profile installed in a user device which is accessible to a radiocommunication network. The operational profile includes data which allows the user device to access the radiocommunication network. In such a method, the user device carries out a step of deactivating a current operational profile and activating a passive operational profile. The passive operational profile: prevents the user device from sending to the radiocommunication network at least one location update request and/or at least one attachment request to the radiocommunication network; and allows the user device to receive at least one radio-paging message including a unique identifier for the user device.

A method for capturing a packet from an encrypted session established between a terminal unit and a data server. The packet includes a datum for determining a security key used for the encryption of the packet. The method is implemented by a device routing the packet between the terminal unit and the data server and includes: analysis of a plurality of packets transmitted by the terminal unit and destined for the server; identification of a cooperation packet from among the plurality of analyzed packets, the cooperation packet including the determining datum corresponding to a security key used for the encryption of packets transmitted by the terminal unit to the data server prior to the terminal unit sending the cooperation packet; and decryption of the received cooperation packet using a security key corresponding to the determining datum from the identified cooperation packet.

The invention relates to a method of securing a mobile terminal (UE) able to communicate with a first telecommunication network (2G, 3G, 4G, 5G). According to the method, the terminal periodically emits a unique identifier from an unmodifiable dedicated memory of the terminal and the identifier is transmitted to a core network of the first telecommunication network via a control channel based on a second telecommunication network (LoRa, IoT) of low energy consumption type.
