PERFORMANCE ANALYSIS OF COOPERATION SCHEMES IN EAVESDROPPER ASSISTED RELAY CHANNEL [PDF]

open access: yesICTACT Journal on Communication Technology, 2014
The prominence of the wireless communication has been urging the monotonically increasing demand of security and privacy. In wireless systems, the notion of perfect secrecy of information with respect to illegitimate nodes can be ensured via physical ...

Secure Massive MIMO Downlink With Low-Resolution ADCs/DACs in the Presence of Active Eavesdropping

open access: yesIEEE Access, 2020
In this paper we study the secrecy performance of a downlink massive multiple-input multiple-output (MIMO) system in the presence of pilot spoofing attack (PSA). Specifically, the base station (BS), which is equipped with low-resolution analog-to-digital

Effective Secrecy Rate for a Downlink NOMA Network [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2019
In this paper, a novel approach is introduced to study the achievable delay-guaranteed secrecy rate, by introducing the concept of the effective secrecy rate (ESR). This study focuses on the downlink of a non-orthogonal multiple access (NOMA) network with one base station, multiple single-antenna NOMA users and an eavesdropper.

Downlink Physical Layer Security Transmission Method Based on Zero-sum Game [PDF]

open access: yesJisuanji gongcheng, 2018
In the Multi-downlink network,the interference among nonorthogonal channels and the malicious interference makes destination nodes not meet the demand of Quality of Service(QoS).So a security transmission method based on zero-sum game model is proposed ...

Antenna selection algorithm based on cut-off rate for secure spatial modulation with finite alphabet input

open access: yesTongxin xuebao, 2020
For the security transmission of artificial noise with finite alphabet inputs in secure spatial modulation system,an antenna selection algorithm based on cut-off rate (COR) was proposed.Considering that it was difficult to obtain the closed-form ...

Simultaneous Wireless Information and Power Transfer in Multi-User OFDMA Networks with Physical Secrecy

open access: yesSensors, 2022
This paper considers simultaneous wireless information and power transfer (SWIPT) from a base station to multiple Internet of Things (IoT) nodes via orthogonal frequency-division multiple access (OFDMA), where every node can eavesdrop on the subcarriers ...

On the secrecy rate of interference networks using structured codes [PDF]

open access: yes2009 IEEE International Symposium on Information Theory, 2009
This paper shows that structured transmission schemes are a good choice for secret communication over interference networks with an eavesdropper. Structured transmission is shown to exploit channel asymmetries and thus perform better than randomly generated codebooks for such channels.

On the Performance of Low-Altitude UAV-Enabled Secure AF Relaying With Cooperative Jamming and SWIPT

open access: yesIEEE Access, 2019
This paper proposes a novel cooperative secure unmanned aerial vehicle (UAV) aided transmission protocol, where a source sends confidential information to a destination via an energy-constrained UAV-mounted amplify-and-forward relay in the presence of a ...

Information Leakage Rate of Optical Code Division Multiple Access Network Using Wiretap Code

open access: yesEntropy, 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 ...
