WIPO Patent Application WO/2009/156108
Kind Code:

Abstract:
The invention relates to a method for releasing a service provided by an electronic appliance (100). According to said method, a registration request (114) is produced by the appliance (100) and sent (S7) to the registration server (300). The registration server (300) then produces a registration confirmation (305) and sends (S9) it to the appliance (100) where the service is then released by receiving and recording (S10) the registration confirmation (305) on the appliance (100). A trustworthy entity (200) then sets up (S6, S12) a time frame on the registration server (300) such that the registration server (300) sends a registration confirmation (305) only for a registration request (114) received within the time frame, and the appliance (100) sends the registration request (114) to the registration server (300) within said time frame.
