چکیده انگلیسی:

Ultra-reliability low-latency communication (uRLLC) is a new service category of the fifthgeneration (5G) mobile wireless networks, also plays a crucial role in the sixth-generation (6G) networks. Given the openness of the wireless environment, the security and confidentiality of uRLLC are of utmost important. Since traditional cryptography methods often feature significant complex designs and processing delays, physical layer security (PLS) technologies exploiting the inherent properties of the wireless medium have become a promising solution to secure wireless communications. However, most existing PLS methods assume a finite block-length regime, which cannot cater to uRLLC with short block-lengths. In this paper, the PLS technologies for uRLLC were comprehensively investigated. First, we reviewed the typical characteristics of the next-generation mobile networks and analyzed the threats faced by the physical layer. Then, we introduced the traditional solutions and performance metrics of PLS with a finite blocklength regime. Furthermore, we discussed several physical layer technologies and observed their influence on PLS. Additionally, this study also analyzed the impact of the unique characteristics of 5G networks on communication securit, such as the mobility.
