Capacity Bounds for Identification With Effective Secrecy
2023 IEEE International Symposium on Information Theory (ISIT), 2023 An upper bound to the identification capacity of discrete memoryless wiretap channels is derived under the requirement of semantic effective secrecy, combining semantic secrecy and stealth constraints. A previously established lower bound is improved by applying it to a prefix channel, formed by concatenating an auxiliary channel and the actual channel.

On the Binary Input Gaussian Wiretap Channel with/without Output Quantization
Entropy, 2017 In this paper, we investigate the effect of output quantization on the secrecy capacity of the binary-input Gaussian wiretap channel. As a result, a closed-form expression with infinite summation terms of the secrecy capacity of the binary-input Gaussian

PHYSICAL LAYER SECRECY ON WIRELESS NETWORK
Tạp chí Khoa học Đại học Đà Lạt, 2016 In this paper, we present an approach for wireless security based on physical layer. The basic principle of physical layer secrecy (PHY Secrecy) is ensuring secure information transmission in the the system that consists of illegal receiver without using

On Physical Layer Security Over the Fisher-Snedecor
IEEE Access, 2018 In this paper, we initially investigate the physical layer security over device-to-device communications, where the channel is modeled from the Fisher-Snedecor .T distribution.

New Result on the Feedback Capacity of the Action-Dependent Dirty Paper Wiretap Channel
Entropy, 2021 The Gaussian wiretap channel with noncausal state interference available at the transmitter, which is also called the dirty paper wiretap channel (DP-WTC), has been extensively studied in the literature. Recently, it has been shown that taking actions on

Hybrid Cache Placement for Physical-Layer Security in Cooperative Networks
IEEE Access, 2018 Due to the broadcast nature of wireless transmission, traditional wireless two-hop relaying is vulnerable for eavesdroppers to overhear messages. In order to enhance the physical-layer security, this paper studies one cooperative network with caching ...

E - Capacity - Equivocation Region of Wiretap Channel [PDF]
Journal of Universal Computer Science, 2021 One of the problems of information - theoretic security concerns secure communication over a wiretap channel. The aim in the general wiretap channel model is to maximize the rate of the reliable communication from the source to the legitimate receiver ...

The secrecy capacity of practical quantum cryptography [PDF]
SPIE Proceedings, 2003 Quantum cryptography has attracted much recent attention due to its potential for providing secret communications that cannot be decrypted by any amount of computational effort. This is the first analysis of the secrecy of a practical implementation of the BB84 protocol that simultaneously takes into account and presents the {\it full} set of complete ...
