First Claim
1. A method for secure routing of information and addressing of a service and of parties to the service in a telecommunication system that includes a telecommunication terminal, a telecommunication network, a service provider connected to the telecommunication network, a service apparatus connected to the telecommunication network for mediating the service, and a communication link connecting the telecommunication terminal and the service apparatus, said method comprising the steps of:
- providing the telecommunication terminal with a terminal-specific unambiguous identifier;
addressing the service apparatus from the telecommunication terminal by sending a predetermined connection setup request from the telecommunication terminal to the service apparatus;
providing at least one of the service apparatus and the service mediated by the service apparatus with a service-specific unambiguous identifier associated with predetermined keys for at least one of encryption and digital signing; and
sending one of a network address of the service provider and information relating to the mediated service from the telecommunication terminal to the service apparatus via the communication link.

Abstract
A method and system for secure routing of information and addressing of a service and of the parties to the service in a telecommunication system that includes a telecommunication terminal, a telecommunication network, a service provider connected to the telecommunication network, a service apparatus connected to the telecommunication network, and a communication link between the telecommunication terminal and the service apparatus. The service apparatus and/or the service indicated by the apparatus, and the telecommunication terminal, are each provided with an unambiguous identifier associated with predetermined encryption and/or digital signing keys. A given service apparatus is addressed by means of the telecommunication terminal by sensing a predetermined connection setup request from the telecommunication terminal to the service apparatus. The service provider'"'"'s network address and/or other information relating to the selected service is sent from the telecommunication terminal to the service apparatus via the communication link, which may be based on Bluetooth technology.
