Backward-Compatible Tag-Based PHY Authentication for Secure WLAN Sensing

Driven by ongoing standardization efforts, Wi-Fi sensing has recently emerged as a promising functionality within wireless local area networks WLANs. However, due to the use of standard null-data packets NDPs to estimate the channel, conventional Wi-Fi sensing systems are susceptible to spoofing...

Security Analysis of RIS-Assisted Physical-Layer Authentication over Multipath Channels

In physical layer authentication, verification of a user's identity is based on the characteristics of the transmission channel through which signals are delivered to the authenticator Bob. In this paper, we assume that the signals received by Bob pass through a \acRIS controlled by Bob and that...

Channel Prediction-Based Physical Layer Authentication under Consecutive Spoofing Attacks

Wireless networks are highly vulnerable to spoofing attacks, especially when attackers transmit consecutive spoofing packets. Conventional physical layer authentication PLA methods have mostly focused on single-packet spoofing attack. However, under consecutive spoofing attacks, they become...
