Screaming Channels is a project that investigates long-distance side-channel attacks on radio signals emitted by mixed-signal chips. Up to now, our best result is a full key recovery from 10 m (Bluetooth dongle, TinyAES 128, anechoic room). We make our setup and code public so that others can reproduce and improve our results.In a nutshell, Screaming Channels is based on these remarks:
Full key recovery now working from 10 m in an anechoic room (Bluetooth dongle, TinyAES 128).

Compared to conventional Side Channels, the Screaming Channels leak is strong and broadcast over a potentially long distance by the radio. Hence the attribute Screaming, in contrast with the Whisper of conventional channels.
