It’s simple, reliable, and effective. Shortwave receivers can be made fairly compact. They’re also very prevalent in most countries (every ham transciever), so there’s nothing suspicious to pack. People find numbers stations interesting, so they are often streamed online. One time pads have their logistical shortcomings, but are still the best encryption possible. The OTP can be compromised in known, visible ways, where a phone has myriad invisible ways to be compromised.

It would be near enough to random and less conspicuous than a pad of random numbers when searched.

- ted_dunning 6mo agoIt's called a book cipher and it is definitely subject to various statistical attacks, especially if you have a list of almost all books.
- smegger001 6mo agoYou could probably do something to increase the apparent entropy like xoringing it with an irrational number like tao or pi starting with a digit determined by the date.
