Abstract: In some examples, a method to defend against relay attacks includes recording a first representation of a motion signal associated with a mobile device. The first representation of the motion signal is obtained by remotely sensing the motion of the mobile device. The method also includes receiving data indicative of a second representation of the motion signal associated with the mobile device. The second representation of the motion signal is obtained by sensing the motion of the mobile device in-situ. The method also includes comparing the first representation of the motion signal with the second representation of the motion signal and verifying, based on the results of the comparison, that a relay attack is not present when the first representation of the motion signal is substantially similar to the second representation of the motion signal.
