USE OF TRUSTED-PLATFORM-BASED SHARED-SECRET DERIVATION AND WWAN INFRASTRUCTURE-BASED ENROLLMENT, FOR ESTABLISHING SECURE LOCAL CHANNEL

摘要

PROBLEM TO BE SOLVED: To provide a system and method for establishing a reliable connection on a mobile computing device.;SOLUTION: A shared secret is generated on a trusted platform of a mobile computing device, and transported to a secure channel application. The secure channel application establishes a secure local communication channel between the trusted platform and a SIM (subscriber identity module)/smart card on the mobile computing device. A Diffie-Hellman key exchange is performed and the shared secret, after being received by the SIM/smart card, is provided to a secure channel applet on the SIM/smart card. Once the secure channel application and the secure channel applet on the SIM/smart card both have the shared secret, the secure local communication channel is established.;COPYRIGHT: (C)2011,JPO&INPIT
