“…Later the scheme is implemented in the Galileo based Timing Receiver for Increasing Critical Infrastructures Resilience (GIANO) receivers (Catalano et al, 2020). Improved from an initial analysis in 2019 (Simon Cancela et al, 2019a, 2019bCancela et al, 2019aCancela et al, , 2019b, M. T. Gamba et al, (2020aGamba et al, ( , 2020b built OSNMA in an ARM-based embedded platform and analyzed the computational load of OSNMA under real-time processor load meaning (Gamba et al, 2021). The analysis finds that the functionality that exhibits the worst degradation is the digital signature verification.…”

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 structure open to the public. Signal authentication effectively protects the security of the signal by attaching unforgeable information to one or several elements of the signal. Receivers can verify the authenticity of the signal by extracting and validating this information. Developing good signal authentication schemes requires understanding possible spoofing modes, signal element specialty, and performance evaluation methods. This paper is an overview of navigation signal authentication, where the theories and reported approaches are described in detail. A design/performance matrix that demonstrates the advantages and defects of the signal element and its authentication design is summarized. Recommendations are proposed to improve the robustness, security, efficiency, and implementation hardness for future designs of navigation signal authentication.

“…Despite OSNMA being a relatively new and modern technology still in its test phase, there is already relevant literature related to it encompassing both theoretical work [ 4 , 5 , 6 , 7 , 8 , 9 ] and practical performance assessments [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. In addition to this, there are a few open-source implementations of the OSNMA protocol [ 22 , 23 , 24 , 25 ], and some companies already support it in some of their products, such as Septentrio [ 26 ].…”

We present Galileo Open Service Navigation Message Authentication (OSNMA) observed operational information and key performance indicators (KPIs) from the analysis of a ten-day-long dataset collected in static open-sky conditions in southern Finland and using our in-house-developed OSNMA implementation. In particular, we present a timeline with authentication-related events, such as authentication status and type, dropped navigation pages, and failed cyclic redundancy checks. We also report other KPIs, such as the number of simultaneously authenticated satellites over time, time to first authenticated fix, and percentage of authenticated fixes, and we evaluate the accuracy of the authenticated position solution. We also study how satellite visibility affects these figures. Finally, we analyze situations where it was not possible to reach an authenticated fix, and offer our findings on the observed patterns.
