WTF is "physical math"????

Th subet of math that is used in physics.

cause identifying which sum was correct *IS* basic high school level
mathematics.
Translating a verbal description into a simple arithmetic expression
involving only simple algebraic functions is high-school level math.

That would be true, if the algorithm actually had algebraic experssions in
it, as it stands it's just a bunch of subs that diffuse and confuse
(additions and subtraction, bitshifts, non-linear s-boxes and byte shuffles)
iterated several times per round.

More points on the John Baez crank-o-meter... Claiming to have
"discovered" an
algorithm when it is clear that you don't understand the math behind
it (such as it is)

As i've said, there is no math involved in the algorithm other than addition
and subtraction, it is literally just a bunch of subs designed to diffuse
and confuse.

Use of polynomials to do what? Do you know what a polynomial basis
is?
What about a polynomial ring?

The only polynomial that I use is for the creation of the key, it's a linear
algebraic permutation of a number. the whole algorithm is used on files,
i've designed it that as soon as you choose the file the key ceration
routine runs and the user has to click the button to start the actual
process of diffusing and confusing the content of the file, as such, I am
counting them as two seperate entities. Entity 1 is the KDF, it uses one
very simple linear algebriac polynomial several times during the runtime of
the KDF. Entity 2, has no math other than addition and subtraction of keys
depending on the mode it's in (encoding/decoding).

There is nothing wrong with only having a "little knowledge", but
even now I don't think you realize how much studying you will have to do
to gain enough competence to design and analyze your "own" algorithm.

And most of what you describe is cookbook; it does not involve
much mathematics.

It doesn't involve much at all. My reasoning behind this is pretty
simplistic, there can be no real mathematical attacks on the algorithm if
there is no real mathematics in the algorithm. It is not even remotely
computationally hard.

I am trying to *help*. But to do so, you must be willing to discard
what you think you know, and master secondary school algebra. Read
some books. DO THE EXERCIZES. In particular, learn how to do WORD
PROBLEMS. Learn the use of variables. If you would like some
references, I can provide them. I can also put together a pre-
calculus level exam that will test your knowledge.

I've already started looking into going back to college next semester,
because really, I know very little of anything other than how to code. As
for the offer to put together pre-calculus exams, any help is much
apperciated.
