An efficient authenticated key exchange protocol for wireless body area network

Abstract

Security protocol issues is an essential factor in network communication. The research of authenticated key exchange protocol is a hotspot in information security field at present, and the related research theories are quite mature. However with respect to the emerging wireless body area network (WBAN), there is few appropriate security protocol to guarantee the security of this network. This paper proposes an authenticated key exchange protocol for wireless body area network, which support the selective authentication between nodes pertain to the net, simultaneously two pairs of session key being generated efficiently and succinctly in the process of each certification, afterwards the security proof by BAN logic of such protocol is given out. The analysis indicates that the proposed protocol meets the expectative objectives.
