Integrated Sensing and Communication in 6G Wireless Systems

The field of integrated sensing and communication (ISAC) is rapidly advancing, with a focus on enabling high data rates and sensing accuracy in next-generation 6G wireless systems. Recent research has highlighted the importance of ensuring sensing safety in ISAC systems, particularly in the presence of malicious attacks. The use of reconfigurable intelligent surfaces (RISs) is being explored to enhance sensing and communication capabilities, including indoor localization and beamforming techniques. Additionally, the integration of physical-layer security (PLS) with ISAC is being investigated to provide theoretically secure transmissions and protect against sensing spoofing and communication covertness. Notable papers in this area include:

  • A study on the threat of malicious RISs to sensing safety in ISAC vehicle networks, which proposes a novel threat model and demonstrates the potential for significant errors in velocity and angle-of-departure estimation.
  • A comprehensive review of secure ISAC systems from a PLS perspective, which analyzes the impact of various physical-layer techniques and schemes on the sensing-security trade-off.
