Abstract
In some examples, a device may include an accelerometer configured to provide a measurement of vibration created by relative contact with another device, and a processor, operatively coupled to the accelerometer, configured to: create an encryption key based on, at least, the measurement of the vibration, receive an output encrypted with the encryption key from the another device, and verify the identity of the encryption key by which the output received from the another device is encrypted.
