A SKG Security Challenge: Indoor SKG Under an On-The-Shoulder Eavesdropping Attack. (arXiv:2305.09251v1 [cs.CR])

Physical layer security (PLS) is seen as the means to enhance physical layer
trustworthiness in 6G. This work provides a proof-of-concept for one of the
most mature PLS technologies, i.e., secret key generation (SKG) from wireless
fading coefficients during the channel's coherence time. As opposed to other
works, where only specific parts of the protocol are typically investigated,
here, we implement the full SKG chain in four indoor experimental campaigns. In
detail, we consider two legitimate nodes, who use the …
