Feedback Schemes for the Action-Dependent Wiretap Channel with Noncausal State at the Transmitter [PDF]
Entropy, 2019 In this paper, we propose two feedback coding schemes for the action-dependent wiretap channel with noncausal state at the transmitter. The first scheme follows from the already existing secret key based feedback coding scheme for the wiretap channel ...

Some New Results on the GaussianWiretap Feedback Channel
Entropy, 2019 In this paper, the Gaussian wiretap feedback channel is revisited, and some new resultson its secrecy capacity are obtained. To be specific, first, we show that the Schalkwijk−Kailath (SK)feedback scheme, which achieves the secrecy capacity of the ...

EURASIP Journal on Wireless Communications and Networking, 2009 This paper considers the compound wiretap channel, which generalizes Wyner's wiretap model to allow the channels to the (legitimate) receiver and to the eavesdropper to take a number of possible states.

The Computational Wiretap Channel [PDF]
2018 56th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2018 We present the computational wiretap channel: Alice has some data x and wants to share some computation h(x) with Bob. To do this, she sends f(x), where f is some sufficient statistic for h. An eavesdropper, Eve, is interested in computing another function g(x).

Information Leakage Rate of Optical Code Division Multiple Access Network Using Wiretap Code [PDF]
Entropy, 2023 Secrecy capacity is usually employed as the performance metric of the physical layer security in fiber-optic wiretap channels. However, secrecy capacity can only qualitatively evaluate the physical layer security, and it cannot quantitatively evaluate ...

Gaussian Multiuser Wiretap Channels in the Presence of a Jammer-Aided Eavesdropper [PDF]
Entropy, 2022 This paper considers secure communication in the presence of an eavesdropper and a malicious jammer. The jammer is assumed to be oblivious of the communication signals emitted by the legitimate transmitter(s) but can employ any jamming strategy subject ...

New Result on the Feedback Capacity of the Action-Dependent Dirty Paper Wiretap Channel [PDF]
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

The MIMO Wiretap Channel Decomposed [PDF]
IEEE Transactions on Information Theory, 2018 The problem of sending a secret message over the Gaussian multiple-input multiple-output (MIMO) wiretap channel is studied. While the capacity of this channel is known, it is not clear how to construct optimal coding schemes that achieve this capacity.

Physical Layer Security: Channel Sounding Results for the Multi-Antenna Wiretap Channel [PDF]
Entropy, 2023 Many physical-layer security works in the literature rely on purely theoretical work or simulated results to establish the value of physical-layer security in securing communications.

A Perspective on the MIMO Wiretap Channel [PDF]
Proceedings of the IEEE, 2015 A wiretap channel is a communication channel between a transmitter Alice and a legitimate receiver Bob, in the presence of an eavesdropper Eve. The goal of communication is to achieve reliability between Alice and Bob, but also confidentiality despite Eve’s presence.
