Optimal Equivocation in Secrecy Systems a Special Case of Distortion-based Characterization
, 2013 Recent work characterizing the optimal performance of secrecy systems has made use of a distortion-like metric for partial secrecy as a replacement for the more traditional metric of equivocation.

Rate Adaption for Secure HARQ-CC System with Multiple Eavesdroppers
Entropy, 2020 In this paper, we studied the secure transmission of a hybrid automatic repeat request with chase combining (HARQ-CC) system, under the existence of multiple eavesdroppers and limited latency.

Secrecy Performance of Correlated $\alpha$ -$\mu$ Fading Channels [PDF]
IEEE Communications Letters, 2019 This letter investigates the secrecy performance of the classical Wyner’s wiretap model, where the main channel and eavesdropper channel experience correlated $\alpha $ - $\mu $ fading. Novel and exact expressions for the average secrecy capacity and secrecy outage probability are derived for the considered realistic scenario.

Optimal Number of Transmit Antennas for Secrecy Enhancement in Massive MIMOME Channels
, 2017 This paper studies the impact of transmit antenna selection on the secrecy performance of massive MIMO wiretap channels. We consider a scenario in which a multi-antenna transmitter selects a subset of transmit antennas with the strongest channel gains ...

When Pay is Kept Secret, the Implications on Performance are Revealing [PDF]
, 2013 Key Findings Pay secrecy (in contrast to pay transparency) negatively affects the performance of individuals who are less tolerant to inequity; Pay secrecy negatively affects the perception of the link between performance and pay in individuals ...

Optimal Transmit Antenna Selection for Massive MIMO Wiretap Channels
, 2018 In this paper, we study the impacts of transmit antenna selection on the secrecy performance of massive MIMO systems. We consider a wiretap setting in which a fixed number of transmit antennas are selected and then confidential messages are transmitted ...

On the Secrecy Performance and Power Allocation in Relaying Networks With Untrusted Relay in the Partial Secrecy Regime [PDF]
IEEE Transactions on Information Forensics and Security, 2020 Recently, three useful secrecy metrics based on the partial secrecy regime were proposed to analyze secure transmissions on wireless systems over quasi-static fading channels, namely: generalized secrecy outage probability, average fractional equivocation, and average information leakage.
