A method, system and a component is provided which enables monitoring of usage statistics associated with broadcast or multicast services, distributed via a communications network. Information, such as e.g. the identity of a user client and the identity of a requested service, associated with a request for a long term key (LTK) is stored in a key management system for later retrieval. A statistics client requesting aggregated statistics associated with the information, may request such statistics from a statistics aggregation system, which is configured to compile the requested statistics on the basis of the stored information.
