development of field programmable gate array based encryption module to mitigate man in the middle attack for nuclear power plant data communication network
Nuclear Engineering and Technology, 2018Co-Authors: Mohamed Abdallah Elakrat, Jae Cheon JungAbstract:Abstract This article presents a security module based on a field programmable gate array (FPGA) to mitigate man-in-the-middle cyber attacks. Nowadays, the FPGA is considered to be the state of the art in nuclear power plants IC it also provides acceptable solutions for embedded computing applications that require cybersecurity. The proposed FPGA-based security module is developed to mitigate information-gathering attacks, which can be made by gaining physical access to the network, e.g., a man-in-the-middle attack, using a cryptographic process to ensure data confidentiality and integrity and prevent injecting malware or malicious data into the critical digital assets of a nuclear power plant data communication System. A model-based System Engineering Approach is applied. System requirements analysis and enhanced function flow block diagrams are created and simulated using CORE9 to compare the performance of the current and developed Systems. Hardware description language code for encryption and serial communication is developed using Vivado Design Suite 2017.2 as a programming tool to run the System synthesis and implementation for performance simulation and design verification. Simple windows are developed using Java for physical testing and communication between a personal computer and the FPGA.

Preliminary study of a visible, high spatial resolution spectrometer for DEMO divertor survey
'IOP Publishing', 2021Co-Authors: Gonzalez W., Ph. Mertens, Tokar M., Marchuk O., Mourão F., Biel W., Ch. LinsmeierAbstract:Developments towards DEMO Diagnostic and Control (D&C) System conceptual design are based on a subset of ITER mature diagnostic Systems, whose eligibility for DEMO has been endorsed by their robustness, long lifetime expectancy and feasible remote maintenance [1]. They are devoted to ensure the machine operation in compliance with safety requirements and high availability. In particular, the evolution of divertor spectroscopic measurements on fusion experiments has demonstrated their potential as a control method for divertor protection via detachment control \cite{2,3} (near ultraviolet, 300–400 nm) and monitoring of the plasma-wall interaction (visible range, 400–700 nm) [2]. These characteristics make this method one of the leading candidates for DEMO detachment and radiation control power. In line with the application of a System Engineering Approach [3], initial assessments of design and feasibility of a VIS high spatial resolution spectrometer for the DEMO divertor survey based on early DEMO control requirements are presented and discussed. The proposed System is located at the equatorial port and it is composed of 3 oblique lines of sights (LoS), 9 toroidal mirrors, 6 plane mirrors and 6 spectrometers examining the outer, inner and X-point divertor region, optimized for the monitoring of chord-integrated NUV/VIS signals under parallel divertor plasmas observation. The wavelengths of interest, spatial resolution and main integration issues are reported

Zero to Integration in Eight Months, the Dawn Ground Data System Engineering Challenge
2006Co-Authors: Dubon, Lydia P.Abstract:The Dawn Project has presented the Ground Data System (GDS) with technical challenges driven by cost and schedule constraints commonly associated with National Aeronautics and Space Administration (NASA) Discovery Projects. The Dawn mission consists of a new and exciting Deep Space partnership among: the Jet Propulsion Laboratory (JPL), manages the project and is responsible for flight operation; Orbital Sciences Corporation (OSC), is the spacecraft builder and is responsible for flight System test and integration; and the University of California, at Los Angeles (UCLA), is responsible for science planning and operations. As a cost-capped mission, one of Dawn's implementation strategies is to leverage from both flight and ground heritage. OSC's ground data System is used for flight System test and integration as part of the flight heritage strategy. Mission operations, however, are to be conducted with JPL's ground System. The System Engineering challenge of dealing with two heterogeneous ground Systems emerged immediately. During the first technical interchange meeting between the JPL's GDS Team and OSC's Flight Software Team, August 2003, the need to integrate the ground System with the flight software was brought to the table. This need was driven by the project's commitment to enable instrument Engineering model integration in a spacecraft simulator environment, for both demonstration and risk mitigation purposes, by April 2004. This paper will describe the System Engineering Approach that was undertaken by JPL's GDS Team in order to meet the technical challenge within a non-negotiable eight-month schedule. Key to the success was adherence to fundamental Systems Engineering practices: decomposition of the project request into manageable requirements; integration of multiple ground disciplines and experts into a focused team effort; definition of a structured yet flexible development process; definition of an in-process risk reduction plan; and aggregation of the intermediate products to an integrated final product. In addition, this paper will highlight the role of lessons learned from the integration experience. The lessons learned from an early GDS deployment have served as the foundation for the design and implementation of the Dawn Ground Data System
