Secrecy Outage Performance of a Cooperative Cognitive Relay Network
IEEE Communications Letters, 2017In this letter, we analyze the physical layer secrecy performance of a two-hop cooperative cognitive underlay relay network with a decode and forward relay and a passive eavesdropper. Unlike other works to date, we assume combining of direct and relayed signals at the destination and the eavesdropper.

Does secrecy signal skill? Own-investor secrecy and hedge fund performance
Journal of Banking & Finance, 2021Abstract Using a novel measure of own-investor secrecy, we find that non-disclosure to a fund’s own investors, unlike non-disclosure to the public, does not signal hedge fund skill. Own-investor secretive funds do not significantly outperform transparent funds through an up market, and they significantly underperform their (sub)strategy-matched peers

Secrecy Performance Analysis of Adaptive SSK Transmission
2020 IEEE 31st Annual International Symposium on Personal, Indoor and Mobile Radio Communications, 2020In this paper, we propose an adaptive antenna index (AI) mapping scheme with the aid of partial channel state information (CSI) (i.e., channel gain order information) of legitimate channel. Based on the received partial CSI that is unknown to an eavesdropper (Eve), transmitter (Tx) adapts AI mapping patterns.

Secrecy Performance of Incremental Relaying with Outdated CSI
2018 IEEE International Conference on Communications (ICC), 2018Secrecy performance is investigated for relay networks with multiple antennas Nt at the transmitter. As K relays are available, we propose an incremental threshold relaying scheme with low complexity, where both transmit antenna selection (TAS) and relay selection are deployed without eavesdropper channel state information (CSI).

The Impact of Pay Secrecy on Individual Task Performance
Academy of Management Proceedings, 2010We generate and test a moderated mediation model of the effects of pay secrecy—a pay communication policy restricting employees’ access to information regarding the level of other employees’ pay in the organization—on individual task performance. According to this model, the effects of such a policy are posited to be mediated by informational fairness,

On the secrecy performance of integrated satellite‐aerial‐terrestrial networks
International Journal of Satellite Communications and Networking, 2020SummaryThis paper investigates secure transmission of an integrated satellite‐aerial‐terrestrial network (ISATN), where multiple eavesdroppers (Eves) attempt to overhear the satellite signals cooperatively. The ISATN adopts an unmanned aerial vehicle (UAV) equipped with multiple antennas as a relay with threshold‐based decode‐and‐forward (DF) protocol.

A New MIMO Signal Constellation for Secrecy and Performance Enhancing
2020 International Conference on Information and Communication Technology Convergence (ICTC), 2020This paper presents a new signal constellation for MIMO transmissions. The proposed signal format achieves performance enhancement via space-time coding of linear combination of conventional modulation schemes. In addition, secrecy capability is achieved with artificially added interference terms embedded in the transmitted modulation signal.

Secrecy Performance in Ultra-Dense Networks with Multiple Associations
2020 IEEE Globecom Workshops (GC Wkshps, 2020Network densification is a promising approach to support the ever-increasing required capacity in cellular networks. Besides, securing the gigantic amount of sensitive data transferred within the network has become a critical issue. Ultra-Dense Networks (UDNs) with a massive number of deployed Small Cells (SCs) constitute the new trait of network ...

Physical-Layer Secrecy Performance in Finite Blocklength Case
2015 IEEE Global Communications Conference (GLOBECOM), 2014For physical-layer secrecy performance, existing studies only focus on coding schemes that can achieve the secrecy capacity. However, finite blocklength penalty could be fatal for security of private message. In this paper, we explore the impact of finite blocklength on secrecy for the wiretap channel model.

Pay Secrecy and Performance: The Psychological Research
Compensation Review, 1982Is establishing an open-pay system and abolishing pay secrecy an inexpensive yet simple way for compensation managers to gain employee satisfaction with pay? The jury is still out.
