First Galileo SAS Authenticated Time Solution
Aleix Galan-Figueras, Ignacio Fernandez-Hernandez, Wim De Wilde +5
Spoofing attacks against civilian GNSS receivers have grown more common, especially near conflict zones where they now disrupt civil aviation, maritime operations, and critical inf…
Improving Galileo OSNMA Time To First Authenticated Fix
Aleix Galan, Ignacio Fernandez-Hernandez, Wim De Wilde +2
Galileo is the first global navigation satellite system to authenticate their civilian signals through the Open Service Galileo Message Authentication (OSNMA) protocol. However, OS…
Implementation Considerations for ACAS and Simulation Results
Jón Winkel, Ignacio Fernandez-Hernandez, Cillian O'Driscoll
The Assisted Commercial Authentication Service (ACAS) is a semi-assisted signal authentication concept currently being defined for Galileo, based on the E6-C encrypted signal. Leve…
Semi-Assisted Signal Authentication based on Galileo ACAS
Ignacio Fernandez-Hernandez, Simon Cancela, Rafael Terris-Gallego +9
A GNSS signal authentication concept named semi-assisted authentication is proposed. It is based on the re-encryption and publication of keystream sequences of some milliseconds fr…
Detection of Replay Attacks to GNSS based on Partial Correlations and Authentication Data Unpredictability
Gonzalo Seco-Granados, David Gomez-Casco, Jose A. Lopez-Salcedo +1
Intentional interference, and in particular GNSS spoofing, is currently one of the most significant concerns of the Positioning, Navigation and Timing (PNT) community. With the ado…
