Wireless body area networks (BANs) have drawn much attention from research community and industry in recent years. Multimedia healthcare services provided by BANs can be available to anyone, anywhere, and anytime seamlessly. A critical issue in BANs is how to preserve the integrity and privacy of a person's medical data over wireless environments in a resource efficient manner. This paper presents a novel key agreement scheme that allows neighboring nodes in BANs to share a common key generated by electrocardiogram (ECG) signals. The improved Jules Sudan (IJS) algorithm is proposed to set up the key agreement for the message authentication. The proposed ECG-IJS key agreement can secure data communications over BANs in a plug-n-play manner without any key distribution overheads. Both the simulation and experimental results are presented, which demonstrate that the proposed ECG-IJS scheme can achieve better security performance in terms of serval performance metrics such as false acceptance rate (FAR) and false rejection rate (FRR) than other existing approaches. In addition, the power consumption analysis also shows that the proposed ECG-IJS scheme can achieve energy efficiency for BANs.
近年来，无线体域网（BANs）引起了研究界和业界的广泛关注。BANs提供的多媒体医疗服务可以无缝地在任何时间、任何地点提供给任何人。BANs中的一个关键问题是如何以资源高效的方式在无线环境中保护个人医疗数据的完整性和隐私性。本文提出了一种新颖的密钥协商方案，该方案允许BANs中的相邻节点共享由心电图（ECG）信号生成的公共密钥。提出了改进的朱尔斯·苏丹（IJS）算法来建立用于消息认证的密钥协商。所提出的ECG-IJS密钥协商能够以即插即用的方式保护BANs上的数据通信，而无需任何密钥分发开销。给出了仿真和实验结果，结果表明，所提出的ECG-IJS方案在误接受率（FAR）和误拒绝率（FRR）等几个性能指标方面比其他现有方法具有更好的安全性能。此外，功耗分析还表明，所提出的ECG-IJS方案能够实现BANs的能源效率。
