Probabilistic Detection of GNSS Spoofing using Opportunistic Information. (arXiv:2305.05404v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
Global Navigation Satellite Systems (GNSS) are integrated into many devices.
However, civilian GNSS signals are usually not cryptographically protected.
This makes attacks that forge signals relatively easy. Considering modern
devices often have network connections and onboard sensors, the proposed here
Probabilistic Detection of GNSS Spoofing (PDS) scheme is based on such
opportunistic information. PDS has at its core two parts. First, a regression
problem with motion model constraints, which equalizes the noise of all
locations considering the motion model of …
