Monetary policy, secrecy, and federal funds rate behavior [PDF]
Journal of Monetary Economics, 1985 Abstract The behavior of the Federal Reserve System can be characterized as secretive. One common justification for this secrecy is the financial markets will overreact to information, causing undue variability in interest rates. This paper examines the credibility of this assertion under the post-October 1979 non-borrowed reserves operating ...

On the Performance of Low-Altitude UAV-Enabled Secure AF Relaying With Cooperative Jamming and SWIPT
IEEE Access, 2019 This paper proposes a novel cooperative secure unmanned aerial vehicle (UAV) aided transmission protocol, where a source sends confidential information to a destination via an energy-constrained UAV-mounted amplify-and-forward relay in the presence of a ...

Downlink Physical Layer Security Transmission Method Based on Zero-sum Game [PDF]
Jisuanji gongcheng, 2018 In the Multi-downlink network,the interference among nonorthogonal channels and the malicious interference makes destination nodes not meet the demand of Quality of Service(QoS).So a security transmission method based on zero-sum game model is proposed ...

Power Allocation in MIMO Wiretap Channel with Statistical CSI and Finite-Alphabet Input
, 2014 In this paper, we consider the problem of power allocation in MIMO wiretap channel for secrecy in the presence of multiple eavesdroppers. Perfect knowledge of the destination channel state information (CSI) and only the statistical knowledge of the ...

Mobile jammers for secrecy rate maximization in cooperative networks [PDF]
2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013 We consider a source (Alice) trying to communicate with a destination (Bob), in a way that an unauthorized node (Eve) cannot infer, based on her observations, the information that is being transmitted. The communication is assisted by multiple multi-antenna cooperating nodes (helpers) who have the ability to move.

Feasibility of positive secrecy rate in wiretap interference channels [PDF]
2014 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2014 Interference usually is an adverse phenomenon in wireless networks. However, the interference can potentially be used to boost the secrecy rate in wireless interference channels. This work studies the secrecy rate in a two-user interference network where unintended user may overhear one of the users, namely user 1.
