Regarding a recent posting on a technique of word alteration as a method of encryption, there seems to be some interesting further possibilities.
The basic system takes the first two letters in a word as valid, then shifts all other letters one space forward in the alpha-numeric sequence.
Then, there's a brief clerical 'arms race' when the shift changes to two, three or more spaces.
And if someone was serious about more complex methods, there is the potential for stepwise increase of the shift value according to some mathematical formula. This opens a variety of possibilities with differing, specific structures. Easy to use when the structure is known. Otherwise it's clearly more difficult.
So the basic example, besides its simple structure, was in the Latin script and Latin language - with a picture as well. So its fairly obvious when a simple solution yields an obvious result. The creative use of the clerical shift would create a lot more problems, even if it were restricted to the Latin script and language.
Now consider the VMs. We don't know the script or alphabetic sequence. We don't know the language. And we don't know the nature of the clerical shift, if there was one.
What level of complexity is required to create a virtually unbreakable encryption that can be easily used with a known key?
