Abstract

The physical layer security in the context of the internet of things is still one of the challenges due to the resource constraints of the end terminals and the IoT network heterogeneity. Although it has been adopted by different wireless applications due to its high spectral efficiency, the OFDM physical layer remains a challenge. The frequency hopping technique is used to protect the nodes from jamming and eavesdropping attacks. The cyclic prefix manipulation has been simulated against different time-delayed paths and the simulated results compared to the theoretical ones. The comparison shows a close match and the guard width encryption mechanism worked as desired.
基于ofdm的物联网(IoT)物理层的跳频保护
由于终端资源的限制和物联网网络的异构性,物联网环境下的物理层安全仍然是一个挑战。虽然由于其频谱效率高,已经被不同的无线应用所采用,但OFDM物理层仍然是一个挑战。采用跳频技术保护节点免受干扰和窃听攻击。对不同时延路径下的循环前缀操作进行了仿真,并将仿真结果与理论结果进行了比较。通过比较,可以看出两者的匹配程度非常接近,并且保护宽度加密机制能够正常工作。
