This paper describes thoroughly an authentication solution that is adequately strong, userfriendly and cost efficient. The idea is to use the mobile phone and its SIM (Subscriber Identity Module) as an authentication token in the authentication of the user for all Internet applications. The proposed solution is generic and offers authentication for any Internet applications on any devices connected to any networks. It is combining several standard strong authentication schemes like ISIM, Generic Bootstrapping Architecture (GBA) with the innovative SIM strong authentication mechanisms.This full text paper was peer reviewed at the direction of IEEE Communications Society subject matter experts for publication in the IEEE "GLOBECOM" 2008 proceedings.978-1-4244-2324-8/08/$25.00

This paper describes thoroughly a service called SIM strong authentication which is aiming to provide strong and user-friendly authentication to the Internet Web services. The idea is to extend the usage of the current SIM authentication used in GSM to Internet Web services. The idea of making the mobile phone and its SIM card a universal authentication token is compelling since the mobile phone is definitely the most used device nowadays and the GSM network is currently the largest mobile network and is ubiquitous in much of the world. This service is available anywhere and can support any Internet services. It is ideal for services like Internet Banking, eAdministration or enterprise internal web pages. The SIM strong authentication service is both user-friendly and cost efficient, with a low deployment threshold.

Discovery of services and other named resources is expected to be a crucial feature for the usability of mobile ad-hoc networks (MANETs
