Abstract :

The 2018 Screaming Channels research raised cybersecurity concerns about mixed-signal electronic devices. Fully appreciating those concerns requires background in electrical engineering, cybersecurity, and cryptography. This article provides the necessary foundation and presents the Screaming Channels phenomenon in a way that is understandable for the masses. Electronic devices are becoming smaller and denser, introducing risk that electronic noise from sensitive processing will leak into broadcasts from the device. The 2018 study showed that certain kinds of electronics, mixed-signal system-on-a-chip devices, are susceptible to this type of leak. Devices that leak digital data into their broadcasts jeopardize the security of their communication. This article will extend the Screaming Channels phenomenon to the context of small satellite communications.
