Abstract

In recent years, building and launching satellites has become considerably cheaper, making satellite systems more accessible to an expanding user base. This accessibility has led to a diverse array of applications—such as navigation, communications, and earth observation—that depend on satellites. However, hardware limitations and operational considerations often render cryptographic solutions impractical for these systems. Furthermore, the availability of low-cost software-defined radios has made signal capture, injection, and interference attacks more attainable for a wider range of potential attackers.

Therefore, mitigations must be developed for satellites that have already been launched without adequate protections in place. This talk introduces some of our research into how satellite systems are vulnerable, as well as ways to protect these systems.
