Secrecy Analysis of Context-Aware Short Packet Transmission

Sixth-generation (6G) systems are expected to require enhanced security measures and face new challenges while incorporating communication context. Physical layer security (PLS) techniques emerge as promising solutions for securing contextual communications thanks to its flexibility and adaptability. Applications using short packet transmissions can ben- efit from context-aware PLS. This paper analyzes the security performance of a wiretap channel during the contextual short packet data transmission. We quantify the channel rate for both contextual and non-contextual information and determine the average context-aware rate. Furthermore, the average block error probabilities for both types of information are defined. Monte-Carlo simulations are employed to validate the derived theoretical formulas.
