Query: BANDANA -- Body Area Network Device-to-device Authentication using
  Natural gAit   Secure spontaneous authentication between devices worn at arbitrary location
on the same body is a challenging, yet unsolved problem. We propose BANDANA,
the first-ever implicit secure device-to-device authentication scheme for
devices worn on the same body. Our approach leverages instantaneous variation
in acceleration patterns from gait sequences to extract always-fresh secure
secrets. It enables secure spontaneous pairing of devices worn on the same body
or interacted with. The method is robust against noise in sensor readings and
active attackers. We demonstrate the robustness of BANDANA on two gait datasets
and discuss the discriminability of intra- and inter-body cases, robustness to
statistical bias, as well as possible attack scenarios.
