ABSTRACT:
FIELD OF THE INVENTION
The invention relates to a telephony device comprising a base station which has a connection to a telephone line and a transceiver assembly for communicating with at least one handset from which handset the user may engage in a telephone communication, the system comprising subscription means for validating a handset with the base station by means of subscription data.
The invention relates to a handset and a base station suitable for such a device.
The invention also relates to a subscription method of a handset.
The invention finds interesting applications in the telephony devices satisfying the DECT standard. The invention is also interesting for the standards which imply steps recalling those of said standard and which make use of subscription data.
BACKGROUND OF THE INVENTION
The problem which is posed with this type of system is that during this subscription of a handset to a base station this base station broadcasts subscription data so that it is possible to recover them. These data may thus be copied to another handset which handset is not authorized. This thus forms a considerably fraudulent cause.
SUMMARY OF THE INVENTION
The present invention proposes a device of the type described in the opening paragraph which provides a good invulnerability to fraudulent subscriptions of handsets.
Therefore, such a device is characterized in that it comprises encryption means for encrypting said subscription data.
