1. A method of facilitating the authentication of an IP data transfer between a mobile wireless terminal and a network node via a radio access network (RAN), the method comprising the steps of:

  • generating a public-private key pair;

    obtaining a certificate containing said public key, a unique identifier allocated to a subscriber, and a signature guaranteeing that the public key is associated with the unique identifier, the unique identifier being an identifier allocated to the terminal for the purpose of using the RAN;

    storing the key pair and the certificate on a subscriber identity module (SIM) card;

    coupling the SIM card to the mobile wireless terminal so that processing means of the terminal can access the key pair and the certificate; and

    sending the certificate to a network node, whereby the network node can use the certificate to authenticate the subscriber.
