在以无线方式连接和交换数据的物联网(IoT)应用中，安全扮演着重要的角色。此外，物联网传感器在电源和计算能力方面都存在局限性。因此，开发一种高安全性、低功耗、低复杂度的物联网传感器无线通信收发器具有重要意义。IEEE 802.11ah具有远距离、低功耗、低成本等优点，是开发物联网传感器无线收发信机的理想选择。然而，当前版本的802.11ah标准并没有侧重于增强系统的安全性。在这项研究中，我们通过在802.11ah的物理层提出一种低复杂度和高安全性的加密方法来解决这个问题。由于加密是在物理层进行的，所以我们搭建了仿真来评估加密方法对系统误比特率和误包率性能的影响。我们的研究表明，与一些传统的加密方法相比，我们的加密实现不会对系统的误码率和误码率性能产生影响。此外，仿真还表明，非预期用户在没有正确密钥的情况下完全无法获得所传输的信息。
In the Internet of things (IoT) applications where things are connected and exchanged data wirelessly, security places an important role. In addition, IoT sensors have limitation on the power source and computing ability. Therefore, developing a wireless communication transceiver which is high-security, low power consumption, and low complexity for IoT sensors is significant. With the advantages such as long range, low power, and low-cost, IEEE 802.11ah is a promising candidate for developing IoT sensor’s wireless transceiver. However, the current version of 802.11ah standard does not focus on enhancing the system security. In this research, we solve that problem by proposing a low complexity and high-security encryption method at the physical (PHY) layer of 802.11ah. Because the encryption is processing at the PHY layer, we built the simulation to evaluate the effect of the encryption method to bit error rate (BER) and packet error rate (PER) performance of the system. Our research shows that the implementation of our encryption does not affect to the BER and PER performance of the system while some conventional methods do. In addition, the simulation also shows that unexpected users are entirely unable to obtain the transmitted information without the correct key.
