Abstract:
A communications device for generating a key for use as a shared secret in communications with another communications device. Each communications device comprises a sensor array for measuring a spatially-varying magnetic field originating from a first spatially-varying density of metallic particles comprised in a first battery, when subjected to an excitation magnetic field, and processing means operative to acquire a set of values from the sensor array, which set of values represents the spatially-varying magnetic field, and to derive the key from the set of values. The excitation magnetic field is generated by a magnetic-field generator comprised in one of the communications devices. Thereby, the two communications devices may, when in proximity, generate identical keys by probing the spatially-varying density of metallic particles comprised in the first battery.

Claim (Index 22):
The method of  claim 13 , wherein the sensor array comprises sensors based on any one, or a combination, of inductors, magneto-resistive sensors, Hall-effect sensors, spin transistors, fluxgates, magneto-electrical sensors, and magneto-optical sensors.
