Abstract

A 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.
