<p>A method is described herein which enables a mobile device and a smart card (SIM, UICC) to establish a shared secret KE which can then be used to secure an interface between themselves. A mobile operator helps in the establishment of the shared secret (KE) by taking part in a key exchange between the mobile device and smart card. The mobile operator's involvement is desirable since they can keep track of mobile device-smart card pairs and if necessary they can block the security establishment between the mobile device and the smart card in order to prevent fraudulent behavior.</p> |
