FIELD: physics.
SUBSTANCE: method is performed by performing the first cryptographic mutual authentication between the telecommunications chip-card and the terminal device through the interface of the chip-card reader. The terminal device has a chip-card reader that is operable to connect to the chip-card reader interface, to receive a configuration message through the chip-card reader interface, to save the configuration message in a secure memory and to remove the program from the protected memory means, so that the telecommunications chip-card can only be modified once.
EFFECT: ensuring the registration of a mobile telephone device in a digital cellular mobile telecommunication network.
