New Authentication Scheme for Backscattering Tag Networks
/ 1 min read
🔋 New authentication scheme enhances security in backscattering tag-to-tag networks. A novel physical layer authentication (PLA) scheme has been proposed to address security vulnerabilities in backscattering tag-to-tag networks (BTTNs), which are crucial for Internet of Things applications. This scheme enables direct authentication between a Talker tag and a Listener tag by utilizing their unique output voltage profiles, thus avoiding the computational limitations of traditional methods. To improve performance, the integration of an indoor reconfigurable intelligent surface (RIS) is suggested, which enhances authentication accuracy and extends operational range. Security analyses demonstrate that the proposed method is resilient against various attacks, outperforming existing solutions in both accuracy and robustness, particularly over longer distances.
