Shake a Secure Bluetooth Connection 107

heilbron writes "The Austrian researcher Rene Mayrhofer of the British Lancaster university and his colleague Hans Gellersen developed a technology to simplify a secured wireless connection of mobile devices. With the so-called shake-to-connect technology an authenticated Bluetooth connection between two mobile phones is established by rhythmic shaking. Integrated oscillation sensors, contained in some mobile phone models, form the basis. The two researchers sketched out a prototype, which is intended for Nokia mobile phones. An example is documented in this YouTube video clip. If two mobile phones are shaken together, the software in both devices registers the same shaking frequency and authenticates the radio link. The principle is summed up in a four page PDF document."
