Maximum Secrecy Throughput of Transmit Antenna Selection with Eavesdropper Outage Constraints
IEEE Signal Processing Letters, 2015We evaluate the effective secrecy throughput of the multiple-input multiple-output multiple-antenna eavesdropper (MIMOME) wiretap channel with antenna selection at the legitimate transmitter. The optimal target secrecy rate that maximizes the effective secrecy throughput is obtained and confirmed by numerical results.

On secrecy throughput optimization of a DF relay network subjected to slow fading
2014 IEEE Globecom Workshops (GC Wkshps), 2014This paper investigates the parameter design for the secrecy throughput optimization under a secrecy outage constraint in a DF relay network subjected to fading. The parameters are designed based on the statistical channel state information (SCSI) of the legitimate channel.

Exact secrecy throughput capacity study in mobile ad hoc networks
Ad Hoc Networks, 2018Abstract The secrecy throughput capacity (STC) performance study of mobile ad hoc networks (MANETs) is critical for supporting their applications in security-sensitive scenarios. Despite much work on the scaling law results of MANET STC, the exact STC study of such networks remains an open problem.

Transmission Policies for Improving Physical Layer Secrecy Throughput in Wireless Networks
IEEE Communications Letters, 2012In this letter, we analyze the physical layer secrecy throughput in wireless fading networks with independent eavesdroppers that do not collude. We study the impacts of the total number of eavesdroppers on the secrecy throughput. In addition, we propose two channel-adaptive transmission policies for improving the secrecy throughput.

On the Security–Reliability and Secrecy Throughput of Random Mobile User in Internet of Things
IEEE Internet of Things Journal, 2020Physical-layer security (PLS) in Internet of Things (IoT) has attracted great attentions recently. Although mobility is an intrinsic property of IoT networks, most of the existing works only investigate the secure transmission design for static users. To fill this gap, this article specifically investigates the secrecy throughput maximization problems ...

Optimal secrecy throughput and efficient energy harvesting for SWIPT system
2018 13th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2018In recent years, simultaneous wireless information and power transfer (SWIPT) has attracted people's research interest, but many researchers only consider one of the secrecy throughput and harvested energy. In this paper, we optimize the secrecy throughput and improve the utilization of the harvested energy in a certain way with a based beamforming ...

On the Secrecy Throughput Maximization for MISO Cognitive Radio Network in Slow Fading Channels
IEEE Transactions on Information Forensics and Security, 2014This paper studies the secure multiple-antenna transmission in slow fading channels for the cognitive radio network, where a multiple-input, single-output, multieavesdropper (MISOME) primary network coexisting with a multiple-input single-output secondary user (SU) pair.

Secrecy throughput of MANETs with malicious nodes
2009 IEEE International Symposium on Information Theory, 2009The secrecy throughput of mobile ad-hoc networks (MANETs) with malicious nodes is investigated. The MANET consists of n legitimate mobile nodes and m malicious nodes. Transmissions between legitimate nodes are subject to a delay constraint D. An information theoretic approach for security is applied to achieve secure communication among legitimate ...

Secrecy Rate Pair Constraints for Secure Throughput
2014 IEEE Military Communications Conference, 2014Physical layer security, which is an alternative to traditional cryptographic methods, has emerged as a promising candidate to protect wireless transmissions from an eavesdropper. An important measure of physical layer security is the secrecy outage: the event when the instantaneous secrecy capacity, which for the considered scenario is the difference ...

Throughput and energy efficiency under queueing and secrecy constraints
2012 Conference Record of the Forty Sixth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2012A broadcast model in which the transmitter sends confidential and common messages to two receivers is considered. It is assumed that the common and confidential data is stored in buffers prior to transmission and the transmitter operates under constraints on buffer violation probability.
