摘要： 在物联网系统中，安全性和能效的整合仍然是一个关键挑战，特别是对于无电池和资源受限的设备。 本文通过将其集成到蓝牙低能耗无电池无线传感器网络中，探讨了一种基于背向散射的安全机制的可扩展性和协议无关性。 所提出的方法利用了传统的无线能量传输链路，用于能量收集，以生成额外的识别信号，而不会增加能耗或计算需求。 实验验证表明，该解决方案使用紧凑的低增益天线，确保与尺寸受限的应用（如结构健康监测和智能运输）的兼容性。 此外，这项工作解决了与背向散射动态范围和多节点无线传感器网络场景相关的挑战，讨论了识别信号之间的潜在冲突，并提出了未来改进措施以提高通用性和可扩展性。 研究结果强调了基于背向散射的安全机制在创建安全、可持续和可扩展的物联网部署方面的潜力，适用于各种协议和应用。 显示英文摘要

摘要： The integration of security and energy efficiency in Internet of Things systems remains a critical challenge, particularly for battery-free and resource-constrained devices. This paper explores the scalability and protocol-agnostic nature of a backscattering-based security mechanism by integrating it into Bluetooth Low Energy battery-free Wireless Sensor Network. The proposed approach leverages the Wireless Power Transfer link, traditionally used for energy harvesting, to generate additional identification signals without increasing energy consumption or computational demands. Experimental validation demonstrates the solution's functionality using compact, low-gain antenna, ensuring compatibility with size-constrained applications such as Structural Health Monitoring and smart transport. Furthermore, this work addresses the challenges associated with backscattering dynamic range and multi-node Wireless Sensor Network scenarios, discussing potential collisions between identification signals and proposing future improvements to enhance generalizability and scalability. The findings underscore the potential of the backscattering-based security mechanism for creating secure, sustainable, and scalable IoT deployments across diverse protocols and applications.
