An Empirical Comparison Of Widely Adopted Hash Functions In Digital Forensics: Does The Programming Language And Operating System Make A Difference?, Satyendra Gurjar, Ibrahim Baggili, Frank Breitinger, Alice Fischer

Annual ADFSL Conference on Digital Forensics, Security and Law

Hash functions are widespread in computer sciences and have a wide range of applications such as ensuring integrity in cryptographic protocols, structuring database entries (hash tables) or identifying known files in forensic investigations. Besides their cryptographic requirements, a fundamental property of hash functions is efficient and easy computation which is especially important in digital forensics due to the large amount of data that needs to be processed when working on cases. In this paper, we correlate the runtime efficiency of common hashing algorithms (MD5, SHA-family) and their implementation. Our empirical comparison focuses on C-OpenSSL, Python, Ruby, Java on Windows and …

Two Challenges Of Stealthy Hypervisors Detection: Time Cheating And Data Fluctuations, Igor Korkin

Annual ADFSL Conference on Digital Forensics, Security and Law

Hardware virtualization technologies play a significant role in cyber security. On the one hand these technologies enhance security levels, by designing a trusted operating system. On the other hand these technologies can be taken up into modern malware which is rather hard to detect. None of the existing methods is able to efficiently detect a hypervisor in the face of countermeasures such as time cheating, temporary self-uninstalling, memory hiding etc. New hypervisor detection methods which will be described in this paper can detect a hypervisor under these countermeasures and even count several nested ones. These novel approaches rely on the …

System Wide Trust Contagion Effect, Rian M. Mehta

Theses and Dissertations

Trust is integral in any service industry, especially in the consumeroriented field of aviation. The first step of this research is the reorganization of the importance of trust. To understand its importance on the industry, it is necessary to study trust and its effects in depth. The purpose of this study is to further explore the relationship between the passengers’ trust in automation, and trust in humans. Oftentimes, when automation fails, some human is responsible for harboring the blame. The theory of System Wide Trust (SWT) has only been recently developed, but its effect on the field of aviation is …

Software In Military Aviation And Drone Mishaps: Analysis And Recommendations For The Investigation Process, Veronica Foreman, Francesca Favaro, Joseph Saleh, Christopher Johnson

Faculty Publications

Software plays a central role in military systems. It is also an important factor in many recent incidents and accidents. A safety gap is growing between our software-intensive technological capabilities and our understanding of the ways they can fail or lead to accidents. Traditional forms of accident investigation are poorly equipped to trace the sources of software failure, for instance software does not age in the same way that hardware components fail over time. As such, it can be hard to trace the causes of software failure or mechanisms by which it contributed to accidents back into the development and …

The Effects Of Light Exposure On Flight Crew Alertness Levels, Lori Brown

Faculty Research and Creative Activities Award (FRACAA)

Fatigue is a threat to aviation safety because of the impairments in alertness and performance it creates. One in five pilots admits that they have made a serious error and say that they have had a "near miss" due to sleepiness, and limited effective fatigue countermeasures available in the operational setting. A review of literature and results of this study show the acute alerting effect of blue light to be a potentially useful countermeasure to reduce physiological, perceived, and cognitive fatigue, where conditions allow its use.

Numerical Model Derived Altimeter Correction Maps For Non-Standard Atmospheric Temperature And Pressure, Thomas A. Guinn, Frederick R. Mosher

International Journal of Aviation, Aeronautics, and Aerospace

Altimeter corrections for non-standard temperature pose a challenge because accurate calculations require detailed knowledge of the temperature structure of the atmosphere between the surface and the aircraft. By applying basic hypsometric formulae to high resolution numerical model temperature and moisture output, detailed maps of current and forecasted corrected D-values are created. Corrected D-values provide the altitude difference between the true altitude and the indicated altitude from a pressure altimeter. Unlike standard D-values, the corrected D-value corrects for non-standard pressure in addition to non-standard temperature and is therefore useful for flights below class A airspace. Maps of corrected D-value may help …

Causes And Risk Factors 1 For Fatal Accidents In Non-Commercial Twin Engine Piston General Aviation Aircraft, Douglas D. Boyd

Publications

Accidents in twin-engine aircraft carry a higher risk of fatality compared with single engine aircraft and constitute 9% of all general aviation accidents. The different flight profile (higher airspeed, service ceiling, increased fuel load, and aircraft yaw in engine failure) may make comparable studies on single-engine aircraft accident causes less relevant. The objective of this study was to identify the accident causes for non-commercial operations in twin engine aircraft. A NTSB accident database query for accidents in twin piston engine airplanes of 4-8 seat capacity with a maximum certified weight of 3000-8000lbs. operating under 14CFR Part 91 for the period …

Controlled Rest In Position (Crip): Consumer Perceptions In The United States, Scott R. Winter, Jason Carryl, Stephen Rice

Publications

Controlled rest in position (CRIP) has been suggested as a viable countermeasure to the Federal Aviation Administration (FAA) in the ongoing efforts to combat in-flight pilot fatigue. It is already in use in other parts of the world; however, it is not currently permitted in the United States. While expert opinion suggested it poses little threat to flight safety, with valuable returns in terms of improved crew alertness and performance, there is some doubt about the level of consumer buy-in. This study completed a preliminary investigation into overall consumer willingness to fly, in the use of CRIP procedures in the …

Aviation Security Impacts Of Meteorological And Climatic Disruption, Melanie Wetzel

Aviation / Aeronautics / Aerospace International Research Conference

Commercial and military flight operations are frequently imperiled or disrupted by meteorological conditions. Severe weather events and climate-related factors create aviation security impacts on airport siting and reliability, human safety, economic stability, military defense strategy, aircraft routing and computer systems vulnerability. Climate trends have been associated with increased frequency of storm surge incursions at coastal airports, intense snowfall accumulations, runway closures due to rainstorm runoff, extended periods of fog/stratus restrictions and severe-weather related risk from lightning, hail and icing. The economic and safety impacts of these events are being incorporated into long-term planning by the U.S. Department of Defense (DoD), …

Solving An Age-Old Debate: What Really Controls Altitude And Airspeed?, Juan Merkt

Aviation / Aeronautics / Aerospace International Research Conference

Mismanagement of altitude and/or airspeed is linked to the top three causes of fatal aviation accidents: loss of control inflight (LOCI), controlled flight into terrain (CFIT), and runway excursions during approach and landing (RE). Clearly, the ability to control altitude and airspeed is a critical skill that all pilots must learn. Yet, differing opinions of how the throttle and elevator work to control altitude and speed can lead to confusion in the cockpit. Energy management is an effective approach to learn how the controls work. Unfortunately energy principles have not found their way into primary flight training. To help bridge …

Unmanned Insecurity: The Safety And Privacy Issues Of Unmanned Aircraft Information Assurance, Donna A. Dulo Ph.D.

Aviation / Aeronautics / Aerospace International Research Conference

Information assurance and computer security are foundational paradigms in ground based information systems. However, in the aerial realm of unmanned systems, information security often takes the proverbial back seat to high visibility issues such as safety and privacy. Yet, a secure unmanned aircraft is a basic tenant of safety and privacy in the operational arena. Information assurance and security that are enveloped into an unmanned aircraft protect the systems data, communications, as well as internal operations and permeates not only the aircraft’s systems, but also the system’s interactions with satellites, ground stations, and other aerial entities that share data and …

Danger In The Training Gap, William Korner

Aviation / Aeronautics / Aerospace International Research Conference

Loss of Control in flight has accounted for the largest share of worldwide passenger deaths over the past ten years. Not Controlled Flight into Terrain, not equipment failure or malfunction, not even weather – but Loss of Control, in flight.

And there is a disturbing caveat to this fact: In every one of those accidents over the past ten years where there was a large loss of life – highly trained and legally qualified pilots were at the controls of the aircraft involved. Meaning these accidents should have been preventable – yet they were not, because the pilots in command …

Risk Perception In Aviation Students: Weather Matters, Ric Ferraro Phd, Darci Vandyke, Mary Zander, Krista Anderson, Bethany Kuehlen

International Journal of Aviation, Aeronautics, and Aerospace

Sixty-three aviation major students and 71 non-aviation major students participated in an experiment concerning aviation experience and risk perception (Risk Perception Scale, RPS; Hunter, 2002). Non-aviation students rated three of the RPS risk scenarios (P2Fly, P2Life, P2 Base) as having higher perceived risk than aviation students with the exception of the weather risk scenarios (P2WX). Aviation students perceived the P2WX scenarios to be significantly more risky. These results have implications for how future pilots perceive risk.

Marbles: The Application Of Input-Output Concepts To Safety Management Systems, Tim Brady, A. Stolzer, Anthony Brickhouse, Antonio Cortes, Dan Mccune, Jayathi Raghavan, David Freiwald

Publications

The goal of this research was to apply the economic concept titled Input-Output Analysis to an aviation safety concept titled Safety Management Systems (SMS). Input-Output (IO) is based upon the interrelationships of various components of an economic system and what happens to the system when one or more of those components changes. Since SMS is, by definition, a system with definable components, the research sought to determine if the interrelationships between those components could be determined and quantified. The term ‘‘marbles’’ was used to describe the activities that led to the IO-SMS matrix. Marbles was used as a metaphor for …

Causes And Trends In Maintenance-Related Accidents In Faa-Certified Single Engine Piston Aircraft, Douglas Boyd, A. Stolzer

Publications

The accident rate for general aviation remains high. While most general aviation accident studies have been pilot-focused, there is little research on the involvement of aircraft maintenance errors. We undertook a study to answer this question.

The Microsoft Access database was queried for accidents occurring between 1989 and 2013 involving single engine piston airplanes operating under 14CFR Part 91. Pearson Chi-Square, Fisher’s Exact Test, and Poisson probability were used in statistical analyses.

The rate of maintenance-related general aviation accidents was 4.3 per million flight hours for the 1989–1993 period and remained unchanged for the most recent period (2009–2013). Maintenance errors …
