== This article is missing an elegant Introduction. ==
 
When I read this article before, it had the language "...began by indentifying a Markov Chain..."
 
I was able to understand Markov Chaining to be the mathematical process of identifying when a Shepherd with the following conditions worked his black sheep dog in a particular pasture on Thursday/Thursdays.
1. He has three (3) pastures, on which he grazes his sheep on a rotating basis.
2. He has two (2) Sheep dogs; a black one and a white one, which he alternates working.
3. There are seven named days in a week, which occur in a rotating order, and the shepherd works seven days a week.
 
If I understand correctly, IDEA is a substitution process acting on a PASSWORD DEPENDENT Markov Chain with an astronomical period/periodicity. This as an introduction makes the strength of the algorithm very comprehensible, and demystifies it.
 
As it stands, the article appears to be written for University students of a single discipline, who universally use one set of nomenclature with which ALL are familiar. The article WOULD NOT serve a high school student trying to write a demo IDEA in BASIC or Python. It WOULD serve the persistent cryptanalyst of a nation state in knowing how best to attack it OR cast doubt on its safety for everyday use. Bad guys exist, true, but it is desirable to read something a layman can comprehend. Wikipedia is universally disallowed as a Source for a white paper.
 
Having cast aspersion, I want to document _some_ consideration that Wikipedia is ALSO a place to document suppressed or otherwise secret knowledge which is not available to ALL in University White Papers, so there's that as well.
