A body area network (BAN) is a wireless network of health monitoring sensors designed to deliver personalized healthcare. Securing intersensor communications within BANs is essential for preserving not only the privacy of health data, but also for ensuring safety of healthcare delivery. This paper presents physiological-signal-based key agreement (PSKA), a scheme for enabling secure intersensor communication within a BAN in a usable (plug-n-play, transparent) manner. PSKA allows neighboring nodes in a BAN to agree to a symmetric (shared) cryptographic key, in an authenticated manner, using physiological signals obtained from the subject. No initialization or predeployment is required; simply deploying sensors in a BAN is enough to make them communicate securely. Our analysis, prototyping, and comparison with the frequently used Diffie-Hellman key agreement protocol shows that PSKA is a viable intersensor key agreement protocol for BANs.
人体区域网络（BAN）是一种用于健康监测传感器的无线网络，旨在提供个性化医疗保健服务。确保BAN内传感器之间的通信安全不仅对于保护健康数据的隐私至关重要，而且对于确保医疗保健服务的安全也至关重要。本文提出了基于生理信号的密钥协商（PSKA）方案，这是一种以可用（即即插即用、透明）方式在BAN内实现安全传感器间通信的方案。PSKA允许BAN中的相邻节点使用从受试者获取的生理信号，以经过认证的方式协商出一个对称（共享）加密密钥。无需初始化或预先部署；只需在BAN中部署传感器就足以使其进行安全通信。我们的分析、原型设计以及与常用的迪菲-赫尔曼密钥协商协议的比较表明，PSKA是一种适用于BANs的可行的传感器间密钥协商协议。
