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...

Vehicular Communication Security: Multi-Channel and Multi-Factor Authentication

Secure and reliable communications are crucial for Intelligent Transportation Systems ITSs, where Vehicle-to-Infrastructure V2I communication plays a key role in enabling mobility-enhancing and safety-critical services. Current V2I authentication relies on credential-based methods over wireless...
