LDPC-based coded cooperative jamming codes

2012 IEEE Information Theory Workshop, 2012
We present a practical coded cooperative jamming scheme for the problem of secure communications over the two-way wiretap channel. We design low-density parity-check (LDPC) based codes whose codewords interfere at the eavesdropper's terminal, thus providing secrecy.

Cooperative jamming for secrecy in decentralized wireless networks

2012 IEEE International Conference on Communications (ICC), 2012
Cooperative jamming as a physical layer security enhancement has recently drawn considerable attention. While most existing works focus on communication systems with a small number of nodes, we investigate the use of cooperative jamming for providing secrecy in large-scale decentralized networks consisting of randomly distributed legitimate users and ...

Cooperative jamming for secure communications in MIMO Cooperative Cognitive Radio Networks

2015 IEEE International Conference on Communications (ICC), 2015
Multiple-Input Multiple-Output Cooperative Cognitive Radio Networks (MIMO-CCRNs) have been proposed recently to further improve the spectrum efficiency. In MIMO-CCRNs, secondary users (SUs) equipped with multiple antennas can cooperatively relay the primary signals for the primary users (PUs) while concurrently accessing the same spectrum to send the ...

Testbed for Cooperative Jamming Cancellation in Physical Layer Security

IEEE Wireless Communications Letters, 2020
Cooperative jamming (CJ) can effectively improve the security of wireless communication system in the physical layer, but such improvement is conditional on effective CJ cancellation at the authorized receiver. In this letter, by considering the point-to-point communication system, a CJ cancellation architecture is provided, and a testbed is designed ...

Cooperative jamming in downlink satellite network with hardware impairments

Transactions on Emerging Telecommunications Technologies, 2021
AbstractIn this article, a land mobile satellite communication network with an external jammer to fight against the eavesdropper is investigated, where the hardware impairments are introduced to make the analyses more practical. It is worth noting that three jamming schemes, that is, the Gaussian noise jamming, the friendly jamming, and the scheme ...

Safeguarding RSMA Networks With Cooperative Jamming and Relaying

IEEE Transactions on Vehicular Technology
Cooperative rate-splitting multiple access (C-RSMA) has emerged as a promising solution for increasing spectral efficiency over conventional RSMA. On the other hand, the presence of eavesdroppers seriously compromises secure communications due to the open nature of the wireless channel.

Relay-Assisted Proactive Eavesdropping With Cooperative Jamming and Spoofing

IEEE Transactions on Wireless Communications, 2018
In this paper, we consider a legitimate proactive eavesdropping scenario where a distant central monitor covertly wiretaps the communication between a pair of suspicious users via several multi-antenna full-duplex spoofing relays and a multi-antenna cooperative jammer.

Transmit beamforming and cooperative jamming for MIMOME wiretap channels

2011 Conference Record of the Forty Fifth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2011
Joint transmit beamforming and cooperative jamming for MIMOME (multiple-input multiple-output multi-antenna-eavesdropper) wiretap channel is studied, where the model consists of a transmitter, a friendly jammer, a receiver and an eavesdropper. The optimization problem of finding transmit and jamming covariances to maximize the secrecy rate is non ...

Increasing the information-theoretic secrecy by cooperative relaying and jamming

2012 50th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2012
The use of cooperation to increase the information-theoretic secrecy in a decentralized ad-hoc wireless network is investigated. In particular, four cases of cooperative relaying are analyzed and compared. These cases include the no-cooperation case, the case with single-hop cooperation with multiple relays, the case with single-hop cooperation with ...
