Trustworthy Personalized Computing on Public Kiosks

We present a system in which a user leverages a personal mobile device to establish trust in a public computing device, or kiosk, prior to revealing personal information to that kiosk. We have designed and implemented a protocol by which the mobile device determines the identity and integrity of the software loaded on the kiosk. A similar protocol allows a kiosk owner to verify that the kiosk has loaded only approved software. Our system combines a number of emerging security technologies, including the Trusted Platform Module, the Integrity Measurement Architecture, and new support in x86 processors for establishing a dynamic root of trust. We focus on allowing the user to personalize the computing environment on the kiosk by running his own virtual machine.
