Secrecy capacity of LiFi systems [PDF]
Emerging Imaging and Sensing Technologies for Security and Defence V; and Advanced Manufacturing Technologies for Micro- and Nanosystems in Security and Defence III, 2020 Radio frequency (RF) signals propagate through most materials that we are surrounded by while light is blocked by many of these materials. This feature makes wireless networks based on light (which are also referred to as LiFi networks) inherently more secure.

Secure Estimation and Zero-Error Secrecy Capacity [PDF]
IEEE Transactions on Automatic Control, 2019 We study the problem of securely estimating the states of an unstable dynamical system subject to nonstochastic disturbances. The estimator obtains all its information through an uncertain channel which is subject to nonstochastic disturbances as well, and an eavesdropper obtains a disturbed version of the channel inputs through a second uncertain ...

Evaluating Secrecy Capacity for In-Body Wireless Channels [PDF]
Entropy, 2019 The next generation of implanted medical devices is expected to be wireless, bringing along new security threats. Thus, it is critical to secure the communication between legitimate nodes inside the body from a possible eavesdropper.

RFID Ownership Transfer with Positive Secrecy Capacity Channels. [PDF]
Sensors (Basel), 2016 RFID ownership transfer protocols (OTPs) transfer tag ownership rights. Recently, there has been considerable interest in such protocols; however, guaranteeing privacy for symmetric-key settings without trusted third parties (TTPs) is a challenge still unresolved.

On the Secrecy Capacity of Fading Channels [PDF]
2007 IEEE International Symposium on Information Theory, 2007 We consider the secure transmission of information over an ergodic fading channel in the presence of an eavesdropper. Our eavesdropper can be viewed as the wireless counterpart of Wyner's wiretapper. The secrecy capacity of such a system is characterized under the assumption of asymptotically long coherence intervals. We first consider the full Channel

Realistic Secrecy Performance Analysis for LiFi Systems
IEEE Access, 2021 This paper studies the secrecy performance of light-fidelity (LiFi) networks under the consideration of random device orientation and partial knowledge of the eavesdroppers’ channel state information. Particularly, the secrecy capacity and secrecy

On the secrecy performance of RIS-enabled wireless communications over Nakagami-m fading channels
ICT Express, 2023 This paper examines the secrecy performance of reconfigurable intelligent surface aided wireless communication systems. Specifically, we derive the secrecy outage probability (SOP), intercept probability, probability of non-zero secrecy capacity, and ...
