Abstract [en]

Global Navigation Satellite Systems (GNSS) are vulnerable to jamming, spoong and replaying aacks because of their characteristics. Concerns regarding these aacks are being heightened because unmanned and autonomous vehicles become popular recently. Cryptographic methods have been proposed and are to be implemented in the Galileo and the GPS systems to counter spoong aacks. However, replaying aacks could still potentially harm GNSS receivers by bypassing the cryptographic methods. Distance-decreasing aacks is a strong type of replay aacks: it essentially resolves, from the aacker's point of view, the issue of introducing processing delay by implementing two phases: early detection and late commit. is poster analyzes the feasibility of distance-decreasing aacks against the GNSS navigation message authenticated signals and proposes countermeasures.
