Data Transmission Safety Feature

Abstract:

The invention provides a method and corresponding devices for wireless pairing of two devices for subsequent secure transmission of data. Each device comprises impact sensor circuitry for detecting an impact event made to the device, and is adapted to determine a unique time related value based on the detected impact event, respectively a corresponding time related value based on the detected impact event. The transmitting device is adapted to calculate a hint H for a key K based on the unique time related value, and the receiving device is adapted to calculate the key K based on the hint H and the corresponding time related value.
