Abstract :

Continuing the topics posed in “Understanding How System-on-a-Chip Data can Leak over Radio Transmissions”, this article extends the exploration of data leakage of system-on-a-chip transceivers to real world small satellites. With the emergence of Low Earth Orbit communications networks, small satellites are poised to become an integral part of the world’s communication fabric. The 2018 Screaming Channels research raised cybersecurity concerns about mixed-signal electronic devices including the transceivers used in small satellites. This article will propose a process for identifying data leaks in the broadcast of affected devices and then apply this framework to four target devices to demonstrate effectiveness. The results show how the proposed process identifies the known leak of a device from the 2018 Bluetooth research and potential concerns in additional devices associated with small satellite communications.
