Challenges of Implementing Automatic Dependent Surveillance Broadcast in the Nextgen Air Traffic Management System

The Federal Aviation Administration is in the process of replacing the current Air Traffic Management (ATM) system with a new system known as NextGen. Automatic Dependent Surveillance-Broadcast (ADS-B) is the aircraft surveillance protocol currently being introduced as a part of the NextGen system deployment. The evolution of ADS-B spans more than two decades, with development focused primarily on increasing the capacity of the Air Traffic Control (ATC) system and reducing operational costs. Security of the ADS-B communications network has not been a high priority, and the inherent lack of security measures in the ADS-B protocol has come under increasing scrutiny as the NextGen ADS-B implementation deadline draws near. The research conducted in this thesis summarizes the ADS-B security vulnerabilities that have been under recent study. Thereafter, we survey both the theoretical and practical efforts which have been conducted concerning these issues, and review possible security solutions. We create a classification of the ADS-B security solutions considered and provide a ranking of the potential solutions. Finally, we discuss the most compatible approaches available, given the constraints of the current ADS-B communications system and protocol

The latest advances in wireless communication in aviation, wind turbines and bridges

Present-day technologies used in SHM (Structural Health Monitoring) systems in many implementations are based on wireless sensor networks (WSN). In the context of the continuous development of these systems, the costs of the elements that form the monitoring system are decreasing. In this situation, the challenge is to select the optimal number of sensors and the network architecture, depending on the wireless system’s other parameters and requirements. It is a challenging task for WSN to provide scalability to cover a large area, fault tolerance, transmission reliability, and energy efficiency when no events are detected. In this article, fundamental issues concerning wireless communication in structural health monitoring systems (SHM) in the context of non-destructive testing sensors (NDT) were presented. Wireless technology developments in several crucial areas were also presented, and these include engineering facilities such as aviation and wind turbine systems as well as bridges and associated engineering facilities

Secure Wireless Avionics Intra-Communications the SCOTT approach

Paper presented at DecPS 2018 (held in conjunction with Ada-Europe 2018, 18-22 June, Lisbon, Portugal).This paper presents the objectives and architecture of the use case of secure wireless avionics intracommunications of the European Project SCOTT (secure connected trustable things). SCOTT aims to build trust of the Internet of Things (IoT) in industrial applications. SCOTT addresses multiple issues such as security, safety, privacy, and dependability across 5 industrial domains: automotive, aeronautics, railway, building and healthcare. The aeronautics use case focuses on the application for active flow control (AFC) based on dense wireless sensor and actuator networks (DWSANs). Topics about security, vulnerabilities and safety in the general field of wireless avionics intra-communications (WAICs) will be addressed. The paper presents preliminary conclusions of the vulnerabilities and security solutions across different entities and layers of the aeronautics IoT architecture.info:eu-repo/semantics/publishedVersio

Serverless protocols for inventory and tracking with a UAV

It is widely acknowledged that the proliferation of Unmanned Aerial Vehicles (UAVs) may lead to serious concerns regarding avionics safety, particularly when end-users are not adhering to air safety regulations. There are, however, domains in which UAVs may help to increase the safety of airplanes and the management of flights and airport resources that often require substantial human resources. For instance, Paris Charles de Gaulle airport (CDG) has more than 7,000 staff and supports 30,000 direct jobs for more than 60 million passengers per year (as of 2016). Indeed, these new systems can be used beneficially for several purposes, even in sensitive areas like airports. Among the considered applications are those that suggest using UAVs to enhance safety of on-ground airplanes; for instance, by collecting (once the aircraft has landed) data recorded by different systems during the flight (like the sensors of the Aircraft Data Networks - ADN) or by examining the state of airplane structure. In this paper, our proposal is to use UAVs, under the control of the airport authorities, to inventory and track various tagged assets, such as luggage, supplies required for the flights, and maintenance tools. The aim of our proposal is to make airport management systems more efficient for operations requiring inventory and tracking, along with increasing safety (sensitive assets such as refueling tanks, or sensitive pieces of luggage can be tracked), thus raising financial profit.Comment: 11 pages, Conference, The 36th IEEE/AIAA Digital Avionics Systems Conference (DASC'17
