Abstract: A method and apparatus for personalizing a smart card coupled with a communication device of a user who is a subscriber of a first telecommunication network and wishes to become a subscriber of a second telecommunication network is disclosed. A first authentication key is stored in both the smart card and in an first application server included in the first telecommunication network. A secure session is established with a second application server included in the second telecommunication network via the first telecommunication network by negotiating with the first application server and the second application server in order that the smart card and the second application server agree on an second authentication key.

Abstract: To authenticate a user possessing a first communication terminal (TC1) and a second communication terminal (TC2), the first terminal being connected to an application server (SApp) in order to access a service, this application server being connected to an authentication server (SAuth) capable of communicating with the second terminal, the authentication server (SAuth) receives a user identifier (IdU) transmitted from the first terminal and identifies the second terminal based on the received identifier. The server generates coding data (DonC) and transmits it to one of the two terminals, and transmits a command to the other one of the two terminals to invite the user to provide a set of data (EnsD) using the coding data received by said one of the two terminals. The server compares the set of data with secret data (DonS) using the coding data, in order to allow the user access to the application server (SApp).
