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.

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,

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.

Feasibility of positive secrecy rate in wiretap interference channels [PDF]
2014 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2014 Interference usually is an adverse phenomenon in wireless networks. However, the interference can potentially be used to boost the secrecy rate in wireless interference channels. This work studies the secrecy rate in a two-user interference network where unintended user may overhear one of the users, namely user 1.

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 ...

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. A model is considered in which an adversary not only intercepts the communication from the transmitter to the receiver, but also ...

Rate Adaption for Secure HARQ-CC System with Multiple Eavesdroppers
Entropy, 2020 In this paper, we studied the secure transmission of a hybrid automatic repeat request with chase combining (HARQ-CC) system, under the existence of multiple eavesdroppers and limited latency.

Security Analysis of QAM Quantum-Noise Randomized Cipher System
IEEE Photonics Journal, 2020 Applying the quadrature amplitude modulation (QAM) format, quantum-noise randomized cipher (QNRC) systems hide the signal states in quantum phase noise and amplitude noise to prevent eavesdropping. In this paper, based on the traditional wire-tap channel
