Air traffic tracking platforms such as the OpenSky Network use crowdsourcing to track air world wide. While allows for unprecedented coverage, it comes with challenges concerning integrity of data. More specifically, by delegating data collection task a mostly unknown group individuals, network becomes vulnerable breaches inexperienced or malicious actors. Users might - intentionally not send faulty fake tracker and in this way threaten information provided network. In paper, we provide...

Abstract Despite the Aircraft Communications, Addressing and Reporting System (ACARS) being widely deployed for over twenty years, little scrutiny has been applied to it outside of aviation community. Whilst originally utilized by commercial airlines track their flights provide automated timekeeping on crew, today serves as a multi-purpose air-ground data link many stakeholders including private jet owners, state actors military. Such change caused ACARS be used far beyond its original...

Many wireless communications systems found in aircraft lack standard security mechanisms, leaving them vulnerable to attack.With affordable software-defined radios readily available, a novel threat has emerged which allows wide range of attackers easily interfere with avionic systems.Whilst these vulnerabilities are known, predicting their ultimate effect is difficult.A major factor this how flight crew respond, especially whether extensive training fault handling helps manage attacks.To...

This paper provides up-to-date statistics on SSR Mode S and 1090ES ADS-B usage by military state aircraft from the OpenSky Network. By analysing large host of real-world data collected using more than 700 receivers, we provide insights equipage these aircraft, their capabilities, patterns much more. We publish up-to-date, empirically validated numbers status ongoing deployment based over areas in Europe, North America, other continents, categorize incorporating publicly available sources....

Collision avoidance is one of the most crucial applications with regards to safety global airspace. The introduction mandatory airborne collision systems has significantly reduced likelihood mid-air collisions despite increase in air traffic density. In this paper, we analyze 250 billion aircraft transponder messages received from 126,700 by OpenSky Network over a two-week period. We use data quantify equipage and usage aspects Traffic Alert Avoidance System (TCAS) as it working real world....

This paper exploits publicly available aircraft meta data in conjunction with unfiltered air traffic communication gathered from a global collaborative sensor network to study the privacy impact of large-scale tracking on governments and public corporations. First, we use movement 542 verified used by 113 different identify events relationships real world. We develop spatio-temporal clustering method which returns 47 18 non-public meetings attended dedicated government over course months....

Abstract Airborne collision avoidance systems provide an onboard safety net should normal air traffic control procedures fail to keep aircraft separated. These are widely deployed and have been constantly refined over the past three decades, usually in response near misses or mid-air collisions. Recent years seen security research increasingly focus on aviation, identifying that key wireless links—some of which used avoidance—are vulnerable attack. In this paper, we go one step further...

In this paper, security issues in on-demand grid and cluster computing are analyzed, a corresponding threat model is presented the challenges with respect to authentication, authorization, delegation single sign-on, secure communication, auditing, safety, confidentiality discussed. Three different levels of identified, based on number resource providers, solution producers users, trust relationships between them. It argued that threats associated first two can be handled by employing...

In this paper, a novel architecture for streaming intrusion detection system Grid computing environments is presented. Detection mechanisms based on traditional log-files or single host databases are replaced by database approach. The allows processing of temporal attack data across multiple sites and offers the potential performance benefits in large scale systems, since processed during its natural flow only stored as long necessary analysis. Two cross-site example attacks environment...

In recent times, we have witnessed a trend in which communications data is increasingly collected and made open source by the public. A prominent example tracking of aircraft movements using unencrypted air traffic control (ATC) communication. This paper studies implications such new datasets on operational privacy military government actors. We use publicly available metadata conjunction with unfiltered ATC communication gathered from collaborative sensor network OpenSky. show that these...

Security and data integrity are important aspects in the fields of Grid cluster computing. When these two areas combined, security issues intermingle new concepts needed to ensure protection both users local users. In this paper, a novel dual laned De

In recent years, air traffic communication data has become easy to access, enabling novel research in many fields. Exploiting this new source, a wide range of applications have emerged, from weather forecasting stock market prediction, or the collection intelligence about military and government movements. Typically, these require knowledge metadata aircraft, specifically its operator aircraft category. armasuisse Science + Technology , R&D agency for Swiss Armed Forces, been developing...

The manner in which Aircraft Communications, Addressing and Reporting System (ACARS) is being used has significantly changed over time. Whilst originally by commercial airliners to track their flights provide automated timekeeping on crew, today it serves as a multi-purpose air-ground data link for many aviation stakeholders including private jet owners, state actors military. Since ACARS messages are still mostly sent the clear wireless channel, any sensitive information with can...

Worldwide, voice-based Air Traffic Control (ATC) communications are gradually being replaced with data link-based equivalents, namely the Controller Pilot Data Link Communications (CPDLC) system. This helps to manage high levels of congestion on ATC---under modern traffic these analog voice channels extremely busy, especially at times peak traffic. CPDLC offers ability conduct most ATC actions in form digital text-based messages. As ATC, has no built-in security mechanisms. Furthermore,...
