lecture: Polyglots in Amateur Radio
Practical Matryoshka Protocols for a 21st Century Numbers Station
Through amateur radio, a neighbor can transmit digital messages around the world. All it takes is a bit of software, a bit of hardware, and a large antenna to bounce a signal across the ionosphere to other continents!
This friendly lecture explains how to implement PSK31, a popular digital protocol, in a few lines of Python. After that, the fun starts! We'll learn how to stegonagraphically encode secret messages inside of a PSK31 transmission. We'll also cover how to make polyglots that are valid both as PSK31 and as other protocols.
Following this lecture, a tool for crafting PSK31 transmissions in Python will be released for the first time.
