Approach

In cryptography, there are mathematics but in a very different way than school. Not because it sounds more concreet at all. But because it is about to break theorems (disproof).

Contrary to memory error issues as any flaw in cyber security, you must have math theorem proving prerequisties.

If you would like to seriously professionally work in cryptography, you mandatorely need to have these prerequisties.

• step 1: math to proove theorems:
  • 1: book fo proof
  • 2: or the book: how to proove it if you prefer. Be carefull: the second book is not free and corrections are only available by third party.
• step 2: theorem prooving focusing on cryptology math focused:
• step 3: congrat!!! because you are now able to read papers focusing on real life issues

But the most important remains to do! At thisu point you must have to fly on your own wing on subject that intrest you such as cryptocurencies or peer to peer security!!!

For example, if you like cryptocurrency, you could reach this documentation.

Good luck!
