Rate-Distortion Theory for Secrecy Systems [PDF]
IEEE Transactions on Information Theory, 2013 Secrecy in communication systems is measured herein by the distortion that an adversary incurs. The transmitter and receiver share secret key, which they use to encrypt communication and ensure distortion at an adversary.

Secrecy Rate Optimization for Secure Multicast Communications [PDF]
IEEE Journal of Selected Topics in Signal Processing, 2016 Recently, physical layer security has been recognized as a new design paradigm to provide security in wireless networks. In contrast to the existing conventional cryptographic methods, physical layer security exploits the dynamics of fading channels to enhance security of wireless communications.

Secure broadcasting : The secrecy rate region [PDF]
2008 46th Annual Allerton Conference on Communication, Control, and Computing, 2008 In this paper, we consider a scenario where a source node wishes to broadcast two confidential messages for two respective receivers, while a wire-tapper also receives the transmitted signal. This model is motivated by wireless communications, where individual secure messages are broadcast over open media and can be received by any illegitimate ...

Outage constrained secrecy rate maximization using cooperative jamming [PDF]
2012 IEEE Statistical Signal Processing Workshop (SSP), 2012 We consider a Gaussian MISO wiretap channel, where a multi-antenna source communicates with a single-antenna destination in the presence of a single-antenna eavesdropper. The communication is assisted by multi-antenna helpers that act as jammers to the eavesdropper.

Secrecy & Rate Adaptation for secure HARQ protocols [PDF]
2013 IEEE Information Theory Workshop (ITW), 2013 This paper is dedicated to the study of HARQ protocols under a secrecy constraint. An encoder sends information to a legitimate decoder while keeping it secret from the eavesdrop-per. Our objective is to provide a coding scheme that satisfies both reliability and confidentiality conditions.

Weighted Sum Secrecy Rate Maximization Using Intelligent Reflecting Surface [PDF]
IEEE Transactions on Communications, 2021 This paper aims to investigate the benefit of using intelligent reflecting surface (IRS) in multi-user multiple-input single-output (MU-MISO) systems, in the presence of eavesdroppers. We maximize the weighted sum secrecy rate by jointly designing the secure beamforming (BF), the artificial noise (AN), as well as the phase shift of the IRS.

Secrecy Rate Optimizations for a MISO Secrecy Channel with Multiple Multiantenna Eavesdroppers [PDF]
IEEE Transactions on Wireless Communications, 2016 This paper investigates secrecy rate optimization problems for a multiple-input-single-output (MISO) secrecy channel in the presence of multiple multiantenna eavesdroppers. Specifically, we consider power minimization and secrecy rate maximization problems for this secrecy network.

Secrecy Sum Rate Maximization in Non-orthogonal Multiple Access [PDF]
IEEE Communications Letters, 2016 Non-orthogonal multiple access (NOMA) has been recognized as a promising technique for providing high data rates in 5G systems. This letter is to study physical layer security in a single-input single-output (SISO) NOMA system consisting of a transmitter, multiple legitimate users and an eavesdropper.

Evolutionary Game-Based Secrecy Rate Adaptation in Wireless Sensor Networks
International Journal of Distributed Sensor Networks, 2015 Physical layer security, whose aim is to maximize the secrecy rate of a source while keeping eavesdroppers ignorant of data transmitted, is extremely suitable for Wireless Sensor Networks (WSNs). We therefore, by developing the classical wire-tap channel,
