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 ...

Feasibility of positive secrecy rate in wiretap interference channels [PDF]

open access: yes2014 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.

Mobile jammers for secrecy rate maximization in cooperative networks [PDF]

open access: yes2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013
We consider a source (Alice) trying to communicate with a destination (Bob), in a way that an unauthorized node (Eve) cannot infer, based on her observations, the information that is being transmitted. The communication is assisted by multiple multi-antenna cooperating nodes (helpers) who have the ability to move.

Long-Term Secrecy Throughput and Fairness Tradeoff for Wireless Powered Secure IoT Networks

open access: yesIEEE Open Journal of the Communications Society
This paper focuses on the interplay between secrecy throughput and fairness for a wireless powered secure Internet of Things (IoT) network, where IoT devices harvest energy from an access point (AP), and securely upload their data to the AP by exploiting
