With the increasing demands for sharing confidential information among massive Internet of
Things (IoT) devices in 5G and beyond wireless networks, many applications require the …

The key generation rate (KGR) performance of wireless physical layer (PHY) key generation
can be limited by the quasi-static slow fading environment. In this work, we aim to exploit the …

Backscatter communication (BC) is an emerging radio technology for achieving sustainable
wireless communications. However, the literature still lacks an effective secret group key …

Future sensor networks require energy and bandwidth efficient designs to support the
growing number of nodes. The security aspect is often neglected due to the extra …

This paper investigates wireless secret key generation in 5G+ indoor LiFi networks
operating in the visible light band in the downlink and the infrared band in the uplink. Unlike …

In the context of drone swarms, achieving efficient group secure communication is a
challenging problem, due to the inherent limitations imposed by the drones' limited energy …

The one time pad (OTP) technique can provide information-theoretic security and physical
layer key generation (PLKG) is a promising candidate for OTP. In the joint PLKG and OTP …

In quasi-static environments, the key generation rate (KGR) of wireless physical layer key
generation (PLKG) can be greatly limited. In this paper, we aim to improve the KGR by …

In the era of Internet of Things (IoT), billions of small but smart wireless devices work
together to make our cities more intelligent and sustainable. One challenge is that many IoT …
