Default Cryptography. - 03-23-2014, 07:08 AM

So for school I gotta make a paper about cryptography and one of my points was 'What is the use of combinatorics in cryptography?'. According to my teacher there is something to say about this but I can't find much.

Now I'm hoping you guys got something news to tell me.

From the wiki of Combinatorics
Spoiler


And then from the wiki of cryptology
Spoiler


So basically just talk about how combinatorics is used in making programs with computer science that can crack codes and stuff.

What course are you in?

I am in computer science, we normally use it to know how many events happen that can be counted in my X event and related that to all the events that can happen (in and out of my X) aka Omega or 1.

So, from this we can know % bla bla bla...

Tho, its is only in math classes: algebra, math analises and discrete maths.

Never been to a cryptology class...

@D Kai I've had combinatorics class 3 months ago so I know the basic use of it, which is what you're saying.

The problem I now face is that it seems to have specific uses in cryptography other than searching how many usefull possibilities there are.

There is a thing called Hashing and Salting that is used to protect passwords that somewhat uses that. Look into that might help you a bit.


Look at this, might help you a bit since its a PRACITCAL exemple. Hope it helps.
