Non-intrusive and ambulatory health monitoring of patients' vital signs over Wireless Body Area Networks (WBANs) provides an economical solution to rising costs in the healthcare system. However, due to the lack of security in the operation and communication of resource-constrained medical sensor nodes, the health and medical information provided by the WBANs may not be trusted. To address this issue, lightweight security solutions that are suitable for capability and resource limited body sensor devices must be provided to authenticate the data transmission. The goal of this research project is to develop a lightweight authentication system for resource-constrained WBANs. Findings from the proposed project will provide support for ensuring real-time delivery of accurate and secure medical information in WBANs. The proposed research will also advance the fields of WBANs and trustworthy biomedical computing for healthcare applications. The proposed theories, models, and simulation code can be used by engineers and researchers to design and evaluate security mechanisms for WBAN applications. In addition, an important education objective tightly coupled with the proposed research is to recruit and educate future generation of WBAN engineers. This will be accomplished through curriculum development, student mentoring, and community outreach in these fast changing technical fields of WBAN system engineering, security and mobile health (mHealth).The proposed research aims at realizing physical layer security approaches for WBANs and developing innovative key agreement and message authentication mechanisms. Unlike existing approaches (e.g., biometric-based approaches), the proposed authentication system does not require additional hardware, error reconciliation process and bit synchronization, and thus is suitable for resource-constrained and capacity-limited medical sensor nodes in WBANs. The proposed research tasks include (1) theoretical studies; (2) design of key agreement schemes; (3) development of message authentication system; and (4) system implementation and validation. The theoretical studies focus on the connections between the channel reciprocity, channel dependency and key generation. Based on the results of theoretical studies, practical key agreement schemes that use a set of dynamic wireless channel features among the communication partners will be developed. The project will then design a lightweight authentication system that is adaptive to wireless channels for securing medical data transmission in WBANs. Finally, the project will implement the proposed physical layer security approach in a real resource-constrained WBANs system and investigate the practical system performance limit through experiments. The findings from the project can provide guidelines for physical-channel based security system design and deployment of WBAN applications.

无线身体区域网络（WBAS）对患者生命体征（WBAS）的无侵蚀性和门诊健康监测提供了一种经济的解决方案，以使医疗保健系统成本上升。但是，由于缺乏资源约束的医疗传感器节点的操作和通信，WBAS提供的健康和医疗信息可能不信任。为了解决此问题，必须提供适合功能和资源有限的车身传感器设备的轻型安全解决方案来验证数据传输。该研究项目的目的是开发用于资源受限的WBAN的轻质身份验证系统。拟议项目的发现将为确保在WBAN中实时提供准确且安全的医疗信息提供支持。拟议的研究还将推动用于医疗保健应用的WBAN和值得信赖的生物医学计算领域。工程师和研究人员可以使用提出的理论，模型和仿真代码来设计和评估WBAN应用程序的安全机制。此外，重要的教育目标与拟议的研究紧密相结合，是招募和教育未来的WBAN工程师。这将通过课程开发，学生指导和社区宣传在这些快速不断变化的WBAN系统工程，安全和移动健康（MHealth）的技术领域中实现。拟议的研究旨在实现WBAN的物理层安全方法，并开发创新的关键协议和消息认证机制。与现有的方法（例如，基于生物识别的方法）不同，所提出的身份验证系统不需要其他硬件，错误对帐过程和位同步，因此适用于WBAN中的资源受限和容量有限的医疗传感器节点。拟议的研究任务包括（1）理论研究； （2）关键协议计划的设计； （3）消息身份验证系统的开发； （4）系统实施和验证。理论研究集中于通道互惠，信道依赖性和关键产生之间的联系。根据理论研究的结果，将开发在通信伙伴中使​​用一组动态无线渠道特征的实用关键协议方案。然后，该项目将设计一个轻巧的身份验证系统，该系统适应无线通道，以确保WBAN的医疗数据传输。最后，该项目将在真正的资源受限的WBAN系统中实现所提出的物理层安全方法，并通过实验调查实用的系统性能限制。该项目的发现可以为基于物理通道的安全系统设计和WBAR应用程序部署提供准则。
