Abstract

A system and method for establishing a connection on a mobile computing device. A secret is generated on a trusted platform of the mobile computing device. The secret is transported to a secure channel application. The secure channel application establishes a trusted local communication channel between the trusted platform and a SIM (subscriber identity module)/Smartcard. The secret is received by the SIM/Smartcard. The secret, after being received by the SIM/Smartcard, is provided to a secure channel applet on the SIM/Smartcard. The secure channel applet establishes the trusted local communication channel between the SIM/Smartcard and the trusted platform, wherein the secret is shared by the trusted platform and the SIM/Smartcard.
