pico
--
over summer 2015, i built hardware demonstrations of cryptographic protocols for the pico project, in the cambridge computer security group . this demonstration hardware included a 'coffee machine' (marble run) simulation, a tiny perspex circular saw, a larger perspex door and a full architect's model of a building: all fully authenticated to the pico protocol, controlled via the app. all protocols used a secure bluetooth bit exchange with a raspberry pi, and work was also done to explore RF distance bounding protocols. the above gif shows a secure 'cappucino' (green marble) order being placed.
