Reconfigurable Intelligent Surface-aided Secret Key Generation in Multi-Cell Systems
Lei Hu, Chen Sun, Guyue Li +2
Physical-layer key generation (PKG) exploits the reciprocity and randomness of wireless channels to generate a symmetric key between two legitimate communication ends. However, in…
Disentangled Representation Learning for RF Fingerprint Extraction under Unknown Channel Statistics
Renjie Xie, Wei Xu, Jiabao Yu +3
Deep learning (DL) applied to a device's radio-frequency fingerprint~(RFF) has attracted significant attention in physical-layer authentication due to its extraordinary classificat…
Joint Precoding and Phase Shift Design in Reconfigurable Intelligent Surfaces-Assisted Secret Key Generation
Tianyu Lu, Liquan Chen, Junqing Zhang +2
Key generation is a promising technique to establish symmetric keys between resource-constrained legitimate users. However, key generation suffers from low secret key rate (SKR) in…
Joint Transmit and Reflective Beamforming for RIS-assisted Secret Key Generation
Lei Hu, Guyue Li, Xuewen Qian +2
Reconfigurable intelligent surface (RIS) is a promising technique to enhance the performance of physical-layer key generation (PKG) due to its ability to smartly customize the radi…
Reconfigurable Intelligent Surface for Physical Layer Key Generation: Constructive or Destructive?
Guyue Li, Lei Hu, Paul Staat +4
Physical layer key generation (PKG) is a promising means to provide on-the-fly shared secret keys by exploiting the intrinsic randomness of the radio channel. However, the performa…
