Method for transferring encrypted useful data objects

摘要

An apparatus and method for transferring encrypted useful data objects (NDO) to a first telecommunication terminal (TG1), wherein at least one encrypted useful data object is initially transferred from a switching component to the first telecommunication terminal. Time information (SABS) is transferred from the switching component to the first telecommunication terminal indicating up to which moment in time a rights object (RO) associated with the at least one encrypted useful data object will arrive. Once the rights object received by the first telecommunication terminal, the telecommunication terminal checks if the moment in time indicated in the time information has elapsed. If the moment has not elapsed, the first telecommunication terminal issues a signal relating to the receipt of a useful data object via a user interface.

1. A method for transferring encrypted data objects to a first telecommunication terminal comprising:
transferring at least one encrypted data object to the first telecommunication terminal from a switching component of a telecommunication network; transferring a time information to the first telecommunication terminal from the switching component, specifying the time-point by when a rights object will also have arrived at the first telecommunication terminal, said rights object being assigned to the at least one encrypted data object and containing the key and the usage rights for the assigned data object; the first telecommunication terminal receiving a rights object which is assigned to the at least one data object; the first telecommunication terminal not outputting a signal via a user interface which has been assigned to this first telecommunication terminal, said signal concerning the receipt of a data object, until either the time-point specified in the time information has passed or a predefined time-point in the first telecommunication terminal following receipt of the data object has passed, or the at least one rights object which is received for activating the data object has been received.
