EphemeriShield -- defence against cyber-antisatellite weapons
Rafal Graczyk, Marcus Voelp, Paulo Esteves-Verissimo

TL;DR
The paper proposes a distributed, blockchain-based system to secure satellite ephemeris data against spoofing and man-in-the-middle attacks, enhancing the resilience of space infrastructure.
Contribution
It introduces a novel distributed approach using permissioned ledgers to prevent central points of failure in satellite data dissemination.
Findings
Distributed ledger system prevents single points of failure.
Ensures data integrity and redundancy for satellite ephemerides.
Enhances security against spoofing and tampering attacks.
Abstract
Satellites, are both crucial and, despite common misbelieve, very fragile parts our civilian and military critical infrastructure. While, many efforts are focused on securing ground and space segments, especially when national security or large businesses interests are affected, the small-sat, newspace revolution democratizes access to, and exploitation of the near earth orbits. This brings new players to the market, typically in the form of small to medium sized companies, offering new or more affordable services. Despite the necessity and inevitability of this process, it also opens potential new venues for targeted attacks against space-related infrastructure. Since sources of satellite ephemerides are very often centralized, they are subject to classical Man-in-the-Middle attacks which open venues for TLE spoofing attack, which may result in unnecessary collision avoidance…
