Watch This Space: Securing Satellite Communication through Resilient Transmitter Fingerprinting. (arXiv:2305.06947v1 [cs.CR])

Due to an increase in the availability of cheap off-the-shelf radio hardware,
spoofing and replay attacks on satellite ground systems have become more
accessible than ever. This is particularly a problem for legacy systems, many
of which do not offer cryptographic security and cannot be patched to support
novel security measures.

In this paper we explore radio transmitter fingerprinting in satellite
systems. We introduce the SatIQ system, proposing novel techniques for
authenticating transmissions using characteristics of transmitter hardware
expressed as …
