Summary: This paper investigates physical layer security for a large-scale WSN with random multiple access, and proposes a random jamming scheme to defeat eavesdroppers. Analytical models are developed to characterize transmission reliability and secrecy, and an optimization problem is formulated to maximize the sum secrecy throughput. The results show that the random jamming scheme improves secrecy throughput, and the optimal jamming probability is determined by the trade-off between secrecy and throughput.

Summary: Cellular networks have evolved and LTE systems face increased security threats, particularly regarding user device tracking. The paper proposes an opportunistic uplink power control scheme to minimize successful user tracking by an unknown adversary. This scheme effectively degrades an adversary's inference ability and maximizes the average inference error probability, leading to almost 100% inference error over multiple time slots.

Summary: Reconfigurable intelligent surface (RIS)-aided wireless communications have been studied for physical layer security, showing advantages in terms of security performance compared to traditional MIMO systems. Increasing the number of reflecting elements in RIS significantly improves security performance, while a small number of reflecting elements in RIS do not enhance system performance when NLoS path loss is small.

Summary: This work focuses on the signal-to-interference-plus-noise ratio (SINR) meta distribution in cellular networks, particularly the Poisson model. It shows that the base station density and noise power mainly affect the SINR distribution through the network signal-to-noise ratio (NSNR). For Poisson cellular networks, the SINR MD can be expressed based on a constraint involving the target SINR and target reliability.

Summary: With the rapid growth of the wireless communication industry, the Internet of Vehicles (IoV) has attracted significant attention as an application scenario. Ensuring the security of information transmission is a key challenge in the IoV system. This paper considers the impact of Nakagami-m fading channel characteristics and vehicle position distribution in the real road scenario to propose a system model for analyzing secrecy outage probability. The derived analytical expressions are verified through Monte Carlo simulation and numerical analysis, and the performance and influencing factors of the considered model in the Nakagami-m fading environment are discussed.

Summary: In this work, we investigate the relation between 'information rate' and stochastic thermodynamics quantities such as entropy rate and entropy production. We propose the application of entropy rate and entropy production to practical applications including abrupt event detection, correlation analysis, and control engineering. Utilizing the Fokker-Planck equation, we calculate exact values for information rate, entropy rate, and entropy production and derive various inequalities among them. We also create entropic-informed correlation coefficients and information geometric cost functions for abrupt event detection and optimal thermodynamic control policies respectively.
