随着近年来无线传感器网络和嵌入式计算技术的发展，小型化的普适健康监测设备已经成为现实可行的。除了提供对生理参数的持续监测和分析外，最近提出的无线身体区域网络(WBAN)还结合了环境感知感知功能，从而提高了敏感性和特异性。一些微小的无线传感器，战略性地放置在人体上，创建了一个可以监测各种生命体征的WBAN，为用户和医务人员提供实时反馈。无线体域网络有望给健康监测带来革命性的变化。由于传感器收集个人医疗数据，因此安全和隐私是此类网络的重要组成部分。在这些类型的轻量级网络中实现传统的安全基础设施是一个挑战，因为它们在设计上受到计算和通信资源的限制。在广域网上实现安全通信的一项关键技术是生物识别技术。在本文中，我们提出了一种利用生理信号(心电)来解决WBAN中的安全问题的方法：一种用于无线体域网络的信任密钥管理方案。这种方法管理对称密钥的生成和分发到WBAN(使用心电信号)中的组成传感器，并保护隐私。
With recent advances in wireless sensor networks and embedded computing technologies, miniaturized pervasive health monitoring devices have become practically feasible. In addition to providing continuous monitoring and analysis of physiological parameters, the recently pro- posed Wireless Body Area Networks (WBAN) incorporates context aware sensing for increased sensitivity and specificity. A number of tiny wireless sensors, strategically placed on the human body, create a WBAN that can monitor various vital signs, providing real-time feed-back to the user and medical personnel. The wireless body area networks promise to revolutionize health monitoring. Since the sensors collect personal medical data, security and privacy are important components in this kind of networks. It is a challenge to implement traditional security infrastructures in these types of lightweight networks, since they are by design limited in both computational and communication resources. A key enabling technology for secure communications in WBANs has emerged to be biometrics. In this paper, we present an approach that exploits physiological signals (electrocardiogram (ECG)) to address security issues in WBAN: a Trust Key Management Scheme for Wireless Body Area Network. This approach manages the generation and distribution of symmetric cryptographic keys to constituent sensors in a WBAN (using ECG signal) and protects the privacy.
