Satellite-based Communication (SATCOM) systems are gaining renewed momentum in
Industry and Academia, thanks to innovative services introduced by leading tech companies …

A large number of facts prove that Global Navigation Satellite System (GNSS) has certain
security risks and is threatened by attacks. In particular, GNSS civilian signal receivers have …

Developments in technologies, attitudes and investment are transforming the space
environment, achieving greater accessibility for an increasing number of parties. New and …

As the Global Navigation Satellite System (GNSS) is widely used in all walks of life, the
signal structure of satellite navigation is open, and the vulnerability to spoofing attacks is …

Due to openness and lack of authentication, like other members of the Global Navigation
Satellite System (GNSS) Club, BeiDou-II civilian navigation signals are vulnerable to all …

Abstract Civilian services of Global Navigation Satellite System are threatened by spoofing
attacks since it is hard to determine the authenticity of a navigation signal with a detailed …

All spoofer attacks have different requirements, impacts, success rates and objectives;
therefore, to assess the threat and to develop appropriate counter measures, a clear …

Data and signal authentication schemes are being proposed to address Global Navigation
Satellite Systems'(GNSS) vulnerability to spoofing. Due to the low power of their signals, the …

Cryptography in the form of digital signatures can be part of the solution to the threat of
spoofing and is going to be implemented on Galileo and other Global Navigation Satellite …

Here we delineate a complete satellite-based augmentation system (SBAS) authentication
scheme, including over-the-air rekeying (OTAR), that uses the elliptic curve digital signature …
