The invention relates to a method for transferring encrypted useful data objects (NDO) to a first telecommunication terminal (TG1), comprising the following steps: at least one encrypted useful data object is initially transferred from a switching component of a telecommunication network 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, containing the key and rights of use for the allocated useful data object, will arrive at the first telecommunication terminal. Subsequently, a rights object associated with the at least one useful data object is received by the first telecommunication terminal. The first telecommunication terminal then checks as to whether the moment in time indicated in the time information has elapsed. If said moment has not elapsed, the first telecommunication terminal issues a signal relating to the receipt of a useful data object via a user interface.
