Well, it's a special case of security by obscurity, isn't it? If the language is something unusual, maybe that helps, but if the language is too obscure, you may be identified (by your ethnicity, your history, or your friends/community) as a speaker of it. I guess it does raise the economic cost of "decipherment" some. But many immigrant parents have learned to their embarrassment that this kind of encoding doesn't work too well %^) The Navajo/Na Dene codetalkers (WW II) developed a real arcane jargon, so I was told. Maybe it was because the conditions of war were completely different than their language's environment so they were forced to invent words, or maybe they thought it was a good idea, or whatever. But I believe transcripts of their transmissions are often mostly unintelligible to native Navajo speakers who weren't in the know.
