On the Jamming Power Allocation for Secure Amplify-and-Forward Relaying via Cooperative Jamming
IEEE Journal on Selected Areas in Communications, 2013 In this paper, we investigate secure communications in two-hop wireless relaying networks with one eavesdropper. To prevent the eavesdropper from intercepting the source message, the destination sends an intended jamming noise to the relay, which is referred to as cooperative jamming.

Cooperative jamming and power allocation with untrusty two-way relay nodes
IET Communications, 2014 This study investigates the security of the two-way relaying system with untrusty relay nodes. Cooperative jamming schemes are considered for bi-directional secrecy communications.

User cooperation to mitigate the jamming in OFDMA networks
Wireless Networks, 2021In this paper, jamming and anti-jamming in a time slotted orthogonal frequency division multiple access (OFDMA) are investigated. The users of the network cooperate to mitigate the jamming effect. Interactions among the network users and the jammer are modeled by a mixed integer non-cooperative generalized game which is a NP-hard problem.

Optimal cooperative jamming for security
2011 - MILCOM 2011 Military Communications Conference, 2011In this paper, based on a cooperative jamming scheme, the design of the optimal covariance matrix of the artificial noise produced by a helper that maximizes the secret rate between a source and legitimate destination pair in the presence of multiple eavesdroppers is addressed.

Cooperative Jamming for Secrecy of Wireless Communications
2018 International Conference on Networking and Network Applications (NaNA), 2018This paper explores cooperative jamming for security in wireless networks. No location data of eavesdropper is available, meanwhile no constraint on the figures of eavesdroppers is posited. A cooperative jamming approach is introduced for jamming the eavesdroppers any location in the system, even through the eavesdroppers are established quite adjacent

Uncoordinated Cooperative Jamming for Secret Communications
IEEE Transactions on Information Forensics and Security, 2013We consider a Gaussian wiretap channel model with a single-antenna source, destination and eavesdropper. The communication is assisted by multiple multiantenna helpers that transmit noise to confound the eavesdropper. First, we consider a nulling scheme, in which each helper independently transmits noise, designed to maximize the system secrecy rate ...

Optimal Cooperative Relaying and Jamming for Secure Communication
IEEE Wireless Communications Letters, 2015This letter considers joint cooperative beamforming and jamming schemes in a cooperative relay network where distributed relay nodes perform cooperative beamforming. The problem of interest is to keep the eavesdropper’s signal to interference and noise ratio (SINR) as low as possible while maintaining the legitimate receiver’s SINR requirement ...

Secrecy at Physical Layer in NOMA with Cooperative Jamming
2020 National Conference on Communications (NCC), 2020We have proposed and analyzed secrecy performance of a network architecture which contains a source, two destinations, a friendly jammer (FJ) and an eavesdropper (Eve). To jam the Eve in order to secure the confidential information of both users, the FJ sends a jamming signal while the source sends the combined information signal using non-orthogonal ...
