SpaceDrones 2.0—Hardware-in-the-Loop Simulation and Validation for Orbital and Deep Space Computer Vision and Machine Learning Tasking Using Free-Flying Drone Platforms
(MDPI, 2022-05-06)
The proliferation of reusable space vehicles has fundamentally changed how assets are injected into the low earth orbit and beyond, increasing both the reliability and frequency of launches. Consequently, it has led to the ...
Decoupling RNN Training and Testing Observation Intervals for Spectrum Sensing Applications
(MDPI, 2022-06-22)
Recurrent neural networks have been shown to outperform other architectures when processing temporally correlated data, such as from wireless communication signals. However, compared to other architectures, such as ...
A Practical Guide for Managing Interdisciplinary Teams: Lessons Learned from Coupled Natural and Human Systems Research
(MDPI, 2020-07-09)
Interdisciplinary team science is essential to address complex socio-environmental questions, but it also presents unique challenges. The scientific literature identifies best practices for high-level processes in team ...
Application of Cybernetics and Control Theory for a New Paradigm in Cybersecurity
(Virginia Tech, 2013-11-01)
A significant limitation of current cyber security research and techniques is its reactive and applied nature. This leads to a continuous ‘cyber cycle’ of attackers scanning networks, developing exploits and attacking ...
Physical layer orthogonal frequency-division multiplexing acquisition and timing synchronization security
(Wiley, 2014-08-18)
Orthogonal frequency-division multiplexing (OFDM) has become the manifest modulation choice for 4G standards. Timing acquisition and carrier frequency offset synchronization are prerequisite to OFDM demodulation and must ...
Designing a Block Cipher in Galois Extension Fields for IoT Security
(MDPI, 2021-11-05)
This paper focuses on a block cipher adaptation of the Galois Extension Fields (GEF) combination technique for PRNGs and targets application in the Internet of Things (IoT) space, an area where the combination technique ...
A Multi-Tier Wireless Spectrum Sharing System Leveraging Secure Spectrum Auctions
(IEEE, 2015-10-08)
Secure spectrum auctions can revolutionize the spectrum utilization of cellular networks and satisfy the ever increasing demand for resources. In this paper, a multi-tier dynamic spectrum sharing system is studied for ...
Further Analysis of PRNG-Based Key Derivation Functions
(IEEE, 2019)
The Internet of Things (IoT) is growing at a rapid pace. With everyday applications and services becoming wirelessly networked, security still is a major concern. Many of these sensors and devices have limitations, such ...
Cyberphysical Security Through Resiliency: A Systems-Centric Approach
(2021-06)
Cyberphysical systems require resiliency techniques for defense, and multicriteria resiliency problems need an approach that evaluates systems for current threats and potential design solutions. A systems-oriented view of ...
Framework for Evaluating the Severity of Cybervulnerability of a Traffic Cabinet
(National Academy of Sciences, 2017)
The increasing connectivity in transportation infrastructure is driving a need for additional security in transportation systems. For security decisions in a budget-constrained environment, the possible effect of a cyberattack ...
