Trustworthy and Personalized Computing on Public Kiosks

Many people desire ubiquitous access to their personal computing environments. The authors present a system in which a user leverages a personal mobile device to establish trust in a public computing device, or kiosk, prior to resuming her environment on the kiosk. They have designed a protocol by which the mobile device determines the identity and integrity of all software loaded on the kiosk, in order to inform the user whether the kiosk is trustworthy. The system exploits emerging hardware security technologies, namely the Trusted Platform Module and new support in x86 processors for establishing a dynamic root of trust.
