Counterfactual quantum cryptography network with untrusted relay
International Journal of Modern Physics B, 2015Counterfactual quantum cryptography allows two remote parties to share a secret key even though a physical particle is not in fact transmitted through the quantum channel. In order to extend the scope of counterfactual quantum cryptography, we use an untrusted relay to construct a multi-user network. The implementation issues are discussed to show that

Cross-layer security in two-hop wireless Gaussian relay network with untrusted relays
2013 IEEE International Conference on Communications (ICC), 2013This paper deals with the challenge of providing information-theoretic secrecy in a two-hop wireless channel with multiple untrusted relay nodes. Instead of perfect secrecy (in the information-theoretic sense), of interest here is a cross-layer approach where only parts of relayed information are protected at the physical layer against eavesdropping at

Partial Relay Selection for Secure Outdated-CSI AF in Untrusted-Relay Networks
2019 15th International Wireless Communications & Mobile Computing Conference (IWCMC), 2019In this paper, we study secure outdated-channelstate-information amplify-and-forward (SO-CSI-AF) relaying network using partial relay selection method. The best relay node is chosen based on the maximum instantaneous signal-tonoise ratio (SNR) of the first hop.

Exploiting Adaptive Jamming in Secure Cooperative NOMA with an Untrusted Relay
ICC 2019 - 2019 IEEE International Conference on Communications (ICC), 2019We study secure communications with an untrusted relay for a cooperative non-orthogonal multiple access (NOMA) system, where a base station (BS) serves a near user (NU) and a far user (FU) by the NOMA principle, and transmission between BS and FU is aided by an untrusted relay.

Wireless cooperative communication through link adaptation with untrusted relay assignment is considered. Using sharp channel codes in different transmission modes, reliability for destination and security in the presence of untrusted relays are provided through rate and power allocation. Scenarios with single available relay and opportunistic relaying

Physical-Layer Secret Key Generation With Colluding Untrusted Relays
IEEE Transactions on Wireless Communications, 2016In this paper, we propose a physical-layer secret key generation scheme for multiantenna legitimate nodes with the help of multiple untrusted relays, equipped with multiple antennas. The untrusted relays conform to the relaying transmission protocol of legitimate nodes, but they also eavesdrop the confidential information of an legitimate transmitter ...
