Enhancing Air Traffic Management Security by Means of Conformance Monitoring and Speech Analysis

Abstract

This document describes the concept of an air traffic management security system and current validation activities. This system uses speech analysis techniques to verify the speaker authorization and to measure the stress level within the air-ground voice communication between pilots and air traffic controllers on one hand, and on the other hand it monitors the current air traffic situation. The purpose of this system is to close an existing security gap by using this multi-modal approach. First validation results are discussed at the end of this article.
