Demo Abstract: Leveraging Side-Channels to Turn Processors into Low Overhead Radios
Justin Feng, Timothy Jacques, Omid Abari, Nader Sehatbakhsh · 2023
Traditionally, side channels have been exploited to uncover sensitive information such as cryptographic keys from computing devices. An attacker can extract private information from a device’s processor and memory by using electromagnetic (EM) radiation while code and data are being executed. Rather than seeing side-channels and electromagnetic radiation as vulnerabilities, we consider them as potential wireless communication channels for resource-constrained devices. The main advantage of this approach is completely eliminating the need for a conventional radio and antenna, which offers energy savings, simplicity, and flexibility for resource-constrained devices.
