Secrecy Rate Pair Constraints for Secure Throughput

2014 IEEE Military Communications Conference, 2014
Physical 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), 2012
A 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.

Average Secrecy Throughput Analysis with Multiple Eavesdroppers in the Finite Blocklength

2020 IEEE 31st Annual International Symposium on Personal, Indoor and Mobile Radio Communications, 2020
This paper studies the problem of secure communication from a transmitter to a receiver with the use of short packets under the existence of multiple eavesdroppers, who are overhearing the transmission. We assume that the eavesdroppers are mutually independent.

Secrecy Throughput of MANETs Under Passive and Active Attacks

IEEE Transactions on Information Theory, 2011
The 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. A model under passive attack is first studied, in which the malicious nodes are assumed to be eavesdroppers ...

Minimum Secrecy Throughput Maximization in Wireless Powered Secure Communications

IEEE Transactions on Vehicular Technology, 2018
This paper investigates a wireless powered secure communication network (WPSCN), in which the legitimate users have no constant energy supply and need to be wireless powered for information transmitting. The harvest-then-transmit protocol is adopted in the WPSCN, i.e., the energy access point (EAP) first transfers energy to legitimate users through ...

Secrecy throughput maximization for millimeter wave systems with artificial noise

2016 IEEE 27th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2016
In this paper, we study the secrecy throughput in millimeter wave systems under slow fading channels considering multipath propagation. For the specific propagation characteristics of millimeter wave, we provide transmission scheme designs and a comprehensive secrecy performance analysis. Specifically, we maximize the secrecy throughput under a secrecy

A new scheme to improve the secrecy throughput under the constraints of secrecy outage probability and average transmit power

2014 IEEE International Conference on Communications Workshops (ICC), 2014
The issue of physical layer security for the wireless communication with slow fading is addressed in this paper, and the secrecy outage performance is concerned. The system is modeled as a wiretap channel, and each of the transmitter and receivers is equipped with a single antenna.

Secrecy Throughput Maximization for Full-Duplex Wireless Powered Communication Networks

ICC 2019 - 2019 IEEE International Conference on Communications (ICC), 2019
In this paper, we investigate the secrecy throughput for a full-duplex wireless powered communication network. A multi-antenna base station (BS) transmits energy towards nodes all the time and each node harvests energy prior to its transmission time slot.

An Achievable Secrecy Throughput of Hybrid-ARQ Protocols for Block Fading Channels

2007 IEEE International Symposium on Information Theory, 2007
In applications of wireless packet-oriented data networks, a special coding scheme, the hybrid automatic retransmission request (HARQ) exhibits high throughput efficiency by adapting its error correcting code redundancy to channel conditions. Motivated by the increasing importance of secure communication over wireless networks, we investigate secure ...

Throughput maximization in multiantenna OFDMA downlink under secrecy rate constraints

2014 IEEE Wireless Communications and Networking Conference (WCNC), 2014
This paper deals with the problem of sum rate maximization for a multiuser orthogonal frequency-division multiple access channel with secrecy rate constraints. We consider the case of a multiple-antenna base station (BS) and several single-antenna downlink receivers; a single secure user, a single eavesdropper and several normal users (without secrecy ...
