Abstract
A client 110 may be authenticated by transmitting or beaming a telecommunication network subscriber's authentication to the client from a device 120, over a wireless link. For example, a GSM telephone 120 may authenticate an electronic book 110 to a content providing service within the Internet. The service verifies the authentication using the subscriber's GSM network operator's Authentication Center 161 to generate an authenticator and the client correspondingly generates a local copy of the authenticator using a GSM SIM over the wireless local link. The authentication is then determined by checking that these authenticators match and thereafter the authenticator can be used as a session key to encrypt data in the service.
Claims42
A method comprising:
- receiving at a mobile client a subscriber identity sent from a mobile station comprising a subscriber identity module, the subscriber identity corresponding to a subscriber of a mobile telecommunication network, wherein the mobile telecommunication network is separate from a communication system to which the mobile client is to be authenticated, and wherein the mobile station is separate from the mobile client;
- sending the subscriber identity from the mobile client to an authentication block of the mobile telecommunication network;
- receiving at the mobile client from the authentication block at least one challenge and at least one first secret based on a subscriber's secret specific to the subscriber identity;
- sending from the mobile client the at least one challenge to a subscriber identity module;
- receiving at the mobile client at least one second secret in response to the at least one challenge;
- and
- using the second secret for authenticating the mobile client to the communication system separate from the mobile telecommunication network.

An apparatus, comprising:
- a means for receiving at a mobile client a subscriber identity sent from a mobile station comprising a subscriber identity module, the subscriber identity corresponding to a subscriber of a mobile telecommunication network, wherein the mobile telecommunication network is separate from a communication system to which the mobile client is to be authenticated, and wherein the mobile station is separate from the mobile client;
- a means for sending the subscriber identity to an authentication block of the mobile telecommunication network;
- a means for receiving at the mobile client from the authentication block at least one challenge and at least one first secret based on a subscriber's secret specific to the subscriber identity;
- a means for sending from the mobile client the at least one challenge to a subscriber identity module;
- and
- a means for receiving at the mobile client at least one second secret in response to the at least one challenge wherein the second secret is arranged to be used for authenticating the mobile client to the communication system separate from the mobile telecommunication network.
