«Спрятать и не потерять»: Реализуем DSSS-стеганографию в MP3 на Python. AES-256 против сжатия с потерями

Принято считать, что стеганография в аудио умирает, как только файл пережимают в MP3. Классический метод LSB (замена младших битов) действительно не выдерживает встречи с психоакустической моделью сжатия — данные просто стираются как «неслышимый мусор». Но что, если подойти к задаче не как к замене битов, а как к радиосвязи? В этой статье мы напишем приложение ChameleonLab на Python (PyQt6 + NumPy). Мы откажемся от хрупких методов в пользу военной технологии DSSS (расширение спектра), применим криптографию AES-256 и научим наш сигнал выживать даже при перекодировании в 128kbps. Разберем математику корреляции, борьбу с рассинхронизацией ffmpeg и почему иногда шум — это хорошо.

@jpaskaruk
Rad, thanks for the heads up on the multichannel card from them them - I bought a stereo card for my dad's birthday a few years ago, to upgrade a little pirate internet radio station I run for him. It works an absolute treat. Though now that I think about it there was a lot of confusion with the docs about setting vs versions, and it was a bunch of trial & error to get working with my setup, but flawless after.

Indeed the pro audio world has largely moved away from the simple multichannel analogue signals. Most are running various flavours of #AES, or #MADI or #Dante or others. The DSP side is a whole other beast, and admittedly outside my scope of expertise.

Всегда думал, что хранить целый чанк из блоков воздуха, земли или камней - это тупизм, и что нужно идти от обратного.

Здесь можно почитать про то, как сервер мини-игр #AES умудряется не засоряться "большим" миром в #Luanti.

A very interesting use for those #rtlsdr #sdr dongles: Listen to what your heat cost allocators, water meters etc. are talking all day. And graph it.
Hint: They're really chatty.
And the stuff is surprisingly easy to setup with cheap dongles, i.e. former #DVB-T/ #DAB dongles.

And what is even more impressive: Those little things can do proper #AES...who would've thunk.

@nyanbinary isn't there some #Rindael (aka. #AES) #encryption implementation available?

• Cuz that should yield you proper, fast & symmetric encryption…
