Abstract

In this paper, we undertake experiments to assess the feasibility of generating common secret keys between two bodyworn devices using the near-body channel. Deriving secret keys using the wireless channel is a practical and lightweight alternative to public-key key-agreement approaches. Our results indicate that key generation is good for dynamic scenarios where communicating devices are placed in non-line-of-sight positions on the body. Furthermore, we enhance existing key generation mechanisms by proposing a filtering method to reduce bit mismatch.
