Abstract: At present, with the popularisation of body sensor networks, more and more people concern the problem of personal privacy. Because the key negotiation schemes are the core technology to protect personal privacy, this paper provides two energy efficient key negotiation schemes for body sensor networks deployed on the surface of the human body which are the most practical applications. In our work, we first point that single-hop transmission is more energy efficient than multi-hop transmission, and then, based on the single-hop transmission and star network structure, we use fuzzy commitment technology to establish shared keys between biosensors and PDA under weak time synchronisation mechanism, and use a modified fuzzy extractor technology to establish shared keys between PDA and the remote medical centre. Analyses show that our scheme are more efficient than existing researches, and are suitable to practical body sensor networks.

Keywords: body sensor networks; BSNs; key negotiation; fuzzy commitment; fuzzy extractor; fuzzy logic; human body surfaces; personal privacy; privacy protection; privacy preservation; energy efficiency; biosensors; shared keys; PDAs; remote medical centres.
