Abstract: This workshop mainly focuses on the development of physical-layer security (PLS) technologies and their potential applications for the future beyond fifth-generation (B5G) and sixth-generation (6G) networks. The tremendous growth in connectivity and the ubiquity of wireless communications have resulted in an unprecedented awareness of the importance of security and privacy. Achieving secure and trusted communications is vital for the deployment of future intelligent connected applications, especially life-critical vehicle-to-everything (V2X) applications. However, the heterogeneous, dynamic and decentralized architecture of these networks leads to difficulties for cryptographic key management and distribution. By exploiting the physical characteristics of devices, wireless channels and noise, PLS offers reliable solutions against eavesdropper attacks as complementary approaches to cryptographic techniques.

The workshop aims at sharing the advancements in the PLS field and spreading the adoption in scenarios of B5G and 6G. In order to spark more ideas and future research, we will invite experts and scholars in relevant fields around the world to share their insights into the topics of physical layer security model, mechanism and applications in B5G and 6G networks. We hope to foster an exchange of research results, experiences, and products in the physical layer security domain from both theoretical and practical perspectives.

Title: Reinforcement Learning Based Maritime Communications Against Jamming and Interference

Abstract: Maritime communications with sea surface reflections and sea wave occlusions have to improve communication performance against jamming for booming maritime services with diverse quality of service. In this talk, we formulate a maritime anti-jamming communication game by analyzing the impact of the communication mode and wave height. A safe RL algorithm with a hierarchical structure is designed to compress the high-dimensional action set for large-scale maritime systems and avoid the dangerous anti-jamming policies that cause learning failure in deteriorated maritime communication environments. We also propose a reinforcement learning-based maritime anti-jamming communication scheme, which jointly optimizes the transmit channel and power, relay, and trajectory based on channel conditions, wave height, evaporation effect, quality of service requirement, and jamming characteristics to improve multi-dimensional anti-jamming performance.

Title: Secret key Generation over Wireless Channel from a Non-quantization Perspective

Abstract: Securing wireless communication remains challenging in dynamic mobile environments due to the shared nature of wireless medium and lacking of fixed key management infrastructures. Using physical layer information of radio channel to generate shared secret keys for pairwise wireless devices has become a promising alternative. Most of existing work rely on quantization technique to convert reciprocal channel measurements into digital binaries as secret keys. However, non-simultaneous packet exchanges in time division duplex systems and noise effects in practice usually create random channel measurements with large discrepancy between two users, leading to inconsistent quantization results and mismatched secret bits. In order to overcome the consequences of quantization, some non-quantization techniques are introduced to improve the performance of key generation, although there are still some inherent defects. This talk will introduce our recent work on secret key generation over wireless channel from the non-quantization perspective.
