Partial Relay Selection for Secure Outdated-CSI AF in Untrusted-Relay Networks

2019 15th International Wireless Communications & Mobile Computing Conference (IWCMC), 2019
In this paper, we study secure outdated-channelstate-information amplify-and-forward (SO-CSI-AF) relaying network using partial relay selection method.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.

Secrecy performance of untrusted relay’s cooperation under fading channels

Transactions of Tianjin University, 2011
The secrecy performance of cooperation with an untrusted relay under a quasi-static fading channel is analyzed in this paper. An achievable secrecy rate is provided and the influence of selfish behavior of untrusted relay is analyzed. Furthermore, the secrecy performance of the scheme is discussed and compared with that of the case where the relay is ...

Secure OFDM transmission in wireless networks with untrusted relays

2017 9th International Conference on Wireless Communications and Signal Processing (WCSP), 2017
Physical layer security is becoming a promising technology to face the security challenges of diversified and rapidly-growing wireless applications. In this paper, we propose a three-hop secure Orthogonal Frequency Division Multiplexing (OFDM) transmission protocol for the wireless networks with untrusted relays.

Secret key generation from static channels with untrusted relays

2015 IEEE 11th International Conference on Wireless and Mobile Computing, Networking and Communications (WiMob), 2015
The generation of symmetric cryptographic keys based on reciprocal channel properties has evolved as a promising approach in recent years, especially for devices with only little computational power. Different schemes individually addressing constraints from special setups have been proposed, but most schemes generally suffer from bad performance in ...

The Symmetric Two-Hop Channel with an Untrusted Relay

2018 International Symposium on Information Theory and Its Applications (ISITA), 2018
We study, using information-theoretic security methods, the so-called symmetric two-hop channel with an untrusted relay. In this model, a source wants to send its message reliably and securely to the destination through an honest but curious relay. The relay acts as a passive eavesdropper.
