Peer-to-peer IrLAN [1] is less prone to interference then sound, and being directional is harder to attack if the air-gap is small. Nowadays its probably obscure enough to make creating an exploit prohibitively expensive, even more so if you write your own drivers. With some electronics knowledge you could probably build your own simple transceivers too.
- andai 10y agoYes, I am considering precisely these kinds of solutions! There was an IR LAN project a while back (ten years?) but I can't remember the name (and the concept has skyrocketed in popularity making Googling difficult). Excellent suggestion :)
- JshWright 10y agoHow does an obscure transport help you if it's still just a LAN connection?
- andai 10y agoIn the scenario I am describing it would only ever be used to transmit ASCII for a cryptosystem. I do not require networking or internet or file transfer, just a low bitrate modem for text input and output.
