US 2002/0172190 A1 · Method and apparatus for secure communication and key distribution in a telecommunication system

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.
