On August 10, 2025, the paper “CKM-Assisted Physical-Layer Security for Resilience Against Unknown Eavesdropping Location” by Ladan Khaloopour, Matthias Hollick, and Vahid Jamali was accepted for presentation at the 28th International Workshop on Smart Antennas (WSA 2025) in Erlangen, Germany. The work introduces a novel approach to strengthen wireless communication security against eavesdroppers by leveraging CKM-based optimization techniques. The preprint is available online at arXiv.
Channel Knowledge Map (CKM) is an emerging data-driven toolbox that captures our awareness of the wireless channel and enables efficient communication and resource allocation beyond the state of the art. In this work, we consider CKM for improving physical-layer security (PLS) in the presence of a passive eavesdropper (Eve), without making any assumptions about Eve’s location or channel state information (CSI). We employ highly directional mmWave transmissions, with the confidential message jointly encoded across multiple beams. By exploiting CKM, we derive an algorithm for time and power allocation among the beams that maximizes the absolute secrecy rate under the worst-case scenario for Eve’s location.
