通过越来越多的可穿戴生命体征传感器和位置标签，无线传感器网络 (WSN) 在医疗保健应用中的出现正在获得动力，这些传感器和位置标签可以实时模式连续跟踪医疗保健人员和患者状态/位置。尽管潜在的应用框架范围不断扩大——从院前、院内、门诊和家庭监护，到用于纵向趋势分析的长期数据库收集——现有的无线传感器网络设计和医疗应用要求之间的安全差距仍然没有解决。一般来说，无线传感器网络设备在功率、计算和通信方面都极其有限。它们通常部署在可访问的区域，从而增加了安全漏洞。动态自组织拓扑、多播传输、位置感知、关键数据优先级以及医疗保健应用的不同传感器的协调进一步加剧了安全挑战。本文从医疗保健应用的需求角度分析了各种 WSN 安全机制，并考虑了安全性对于医疗保健行业成功部署普适计算解决方案的重要性。
The emergence of wireless sensor networks (WSNs) in healthcare applications is gaining momentum through the increasing array of wearable vital sign sensors and location tags which can track both healthcare personnel and patient status/ location continuously in real-time mode. Despite the increased range of potential application frameworks - ranging from pre-hospital, in-hospital, ambulatory and home monitoring, to long-term database collection for longitudinal trend analysis - the security gap between existing WSN designs and the requirements of medical applications remains unresolved.Generally, WSN devices are extremely limited in terms of power, computation, and communication. They are often deployed in accessible areas, thus increasing security vulnerabilities. The dynamic ad hoc topology, multicast transmission, location awareness, critical data prioritisation, and co-ordination of diverse sensors of healthcare applications further exacerbate the security challenges. This paper presents an analysis of various WSN security mechanisms from the demanding perspective of healthcare applications, and considers the importance of security to the successful deployment of pervasive computing solutions in the healthcare industry.
