SUBSTANCE: method of providing data objects on rights for issuing to a device has access to encrypted content relating to one of several events and is provided with indication of position, from which the data object on rights can be requested, and event information uniquely associated with the event. The device includes a function of an agent for providing a request for a device which issues data objects on rights from the said position, and data which represent event information. The method involves steps on which a request and data representing event information are received, and a data object on rights is generated, which includes event key information which enables encryption of content data relating to the event uniquely associated with the event information. The event key information is generated using a cryptographic function relative at least part of the event information.
EFFECT: possibility of a device which provides data objects on rights working relatively independent of a content supplier.
