Abstract: Current mechanisms for authenticating communication between devices that share no prior context are inconvenient for ordinary users, without the assistance of a trusted authority. We present and analyse Seeing-Is-Believing (SiB), a system that utilises 2D barcodes and camera-phones to implement a visual channel for authentication and demonstrative identification of devices. We apply this visual channel to several problems in computer security, including authenticated key exchange between devices that share no prior context, establishment of the identity of a TCG-compliant computing platform, and secure device configuration in the context of a smart home.
