打破實體隔離限制傳遞資訊

GitHub 上的 fulldecent/system-bus-radio 這個專案可以打破實體隔離限制傳遞資訊:

Some computers are intentionally disconnected from the rest of the world. This includes having their internet, wireless, bluetooth, USB, external file storage and audio capabilities removed. This is called "air gapping". Even in such a situation, this program can transmit radio.

有些電腦因為種種因素而實體隔離 (像是因為安全因素,或是保密因素),於是就有人研究各種方法傳遞資訊。這隻程式利用 system bus 在 Macbook Air 上產生 AM radio 訊號:

And run it on an Apple MacBook Air (13-inch, Early 2015):

./main

Then use a Sony STR-K670P radio receiver with the included antenna and tune it to 1580 kHz on AM.

這方法好硬... 但也證明了可以藉由這種方法傳遞訊息。

    其實這方法能做的物理調變不夠複雜 ...

    螢幕溢波比較厲害!
