An Energy Conservation Authentication Scheme in Wireless Body Area Network

Abstract

Wireless Body Area Network (WBAN) is an important branch which takes the advantage of the wireless sensor network (WSN) to achieve the corresponding goal in remote healthcare application. Security of WBAN is no doubt a crucial issue while developing telecare medical system. However, high computational costs and energy consumption are required in current mechanisms to confirm the security of communication protocol. Thus, we aim to propose a lightweight version based on symmetric cryptography, xor operation, and one way hash function in guaranteeing the security problem. We have simulated the system according to the NS-2 simulator. The experimental results have demonstrated that the proposed method is superior to related works in terms of energy consumption and communication costs.
