On the Security of the Automatic Dependent Surveillance-Broadcast Protocol

Automatic dependent surveillance-broadcast (ADS-B) is the communications protocol currently being rolled out as part of next generation air transportation systems. As the heart of modern air traffic control, it will play an essential role in the protection of two billion passengers per year, besides being crucial to many other interest groups in aviation. The inherent lack of security measures in the ADS-B protocol has long been a topic in both the aviation circles and in the academic community. Due to recently published proof-of-concept attacks, the topic is becoming ever more pressing, especially with the deadline for mandatory implementation in most airspaces fast approaching. This survey first summarizes the attacks and problems that have been reported in relation to ADS-B security. Thereafter, it surveys both the theoretical and practical efforts which have been previously conducted concerning these issues, including possible countermeasures. In addition, the survey seeks to go beyond the current state of the art and gives a detailed assessment of security measures which have been developed more generally for related wireless networks such as sensor networks and vehicular ad hoc networks, including a taxonomy of all considered approaches.Comment: Survey, 22 Pages, 21 Figure

An evaluation of NASA's program in human factors research: Aircrew-vehicle system interaction

Research in human factors in the aircraft cockpit and a proposed program augmentation were reviewed. The dramatic growth of microprocessor technology makes it entirely feasible to automate increasingly more functions in the aircraft cockpit; the promise of improved vehicle performance, efficiency, and safety through automation makes highly automated flight inevitable. An organized data base and validated methodology for predicting the effects of automation on human performance and thus on safety are lacking and without such a data base and validated methodology for analyzing human performance, increased automation may introduce new risks. Efforts should be concentrated on developing methods and techniques for analyzing man machine interactions, including human workload and prediction of performance

Central Command Rest and Recuperation Hub-to-Hub Airlift Network Analysis

The primary purpose of this research effort was to discover the efficiency and effectiveness of the historical hub-to-hub R&R airlift network. This study analyzed the hub-to-hub aircraft efficiency rates and introduced capacity changes in the airlift network with the use of Arena simulation to improve network performance. Furthermore, this study created simple heuristic options for the future airlift framework required to meet USCENTCOM\u27s forecasted R&R transportation demand under the premise of a CY11 country 1 drawdown and an upscale of combat and support forces within country 2. There were several important outcomes of this research effort. First, this study designed the future framework for R&R airlift passenger operations with a focus on leveraging simple heuristics to increase intertheater commercial aircraft utilization to 89.7 percent while also adding four additional weekly sorties in the strategic port to intratheater hub routes. As a result, this study demonstrated that passenger velocity at the strategic port could be increased by 20.6 hours on the average and 24.9 hours at the 90th percentile with a decrease in the transient passenger footprint at the strategic port by 215 passengers on the average. This transient passenger footprint reduction also opens up further opportunities for cost savings by contracting support personnel and facilities at the strategic port for future operations. Finally, this study found that the use of a simple heuristic could increase commercial aircraft seat utilization rates by approximately 10 percent yielding an estimated $26.5M in yearly savings in contract airlift
