Context-aware physical layer security for future wireless networks
Halise Türkmen, Hüseyin Arslan · 2022
The amount information currently generated and contained in wireless networks is paramount. Additionally, wireless sensing through integrated sensing and communication (ISAC) is being incorporated into the next-generation [B5G, WiFi 7] wireless communication standards, further increasing this information. Faster chips, various network topologies and higher data rates have permitted increased utilization of artificial intelligence (AI) techniques in wireless systems and thus enable accurate predictions of future network and radio environment related phenomenon. Therefore, a capable device can essentially be aware of the user, network, and radio environment activities. These developments have led to the cognitive or context-aware physical layer security (PLS) concept. With this, intelligent wireless devices can anticipate threats and take the necessary precautions dynamically. This chapter will go over radio environment monitoring (REMo), which is the process of collecting, processing and storing the aforementioned information. Then, the context-aware PLS framework will be introduced, with application examples.
