Secure communication system for wearable devices wireless intra body communication

This paper explains how intra-body communication can be used to establish a secure communicationchannel for wearable devices. Intra-body communication transfers data using the human body as its conductor. This paper describes a secure communication system that supports multiple wearable slave devices.

Our prototype, wearable on the wrist, has an integrated processor to control the intra-bodycommunication module. Instead of using radio transmission, the module uses the human body, thus maximizing the security of transmitted signals.
