How does school math differ from IT security studies?

After graduating from high school, I'd like to study something. My question is, how math-intensive is the IT security with information technology degree? I often hear from computer science students that school math and IT math are two completely different worlds. It's as if you're learning math all over again at university. I'm an average math student.

Mathematics at the university is pure logic. You can forget about that with the recruit. I can show you an introductory evidence from the first semester. Already there we were expected to ‘delete’ it or We had to find/recognize approaches to the solution without any plan of evidence techniques.

Of course under ‘not’ looking at the right notation:

Claim: For all a,b

a,b elements of z

a and b are just ⇒ a + b

Proof: its a, b € Z straight

a is straight => there is a k € Z with a = 2k + 1

b is straight => there is l € Z with b = 2l + 1

=> a+b = 2k+1 +2l+1 = 2(k+l) € Z is straight

qed.

That’s why it doesn’t matter whether you’re good at math or not. Some can start more with logic than with blunt computing at school.

I took the IT security module for computer science. Mathematics in it or cryptography likes to resort to asymmetric methods, including non-reversible functions. These then run, for example, over Modulo:

this is now not an official procedure that is only an example of a non-reversible function or with elliptical curves.

It’s not exactly schoolmathe, but it’s still feasible. Discrete logarithm, residual classes, these curves are not exactly schoolmathe, but this should not be your limit.

explaining to a student intelligible how university mathematics is, that is hardly possible.

For comparison: Imagine a basic student who can count up to 100. Now try to explain the Binomic formulas to this primary student. Look out, right?

The comparison is excellent, I must remember 😀
