# Question on the math behind Asymmetric Encryption

So I'm studying Cryptology with Eric Conrad's book and I'm trying to understand that math behind Asymmetric Encryption. The subject areas are factoring prime numbers and also discrete logarithm, alot of theory and I just don't see how it applies right now.

Eric does a pretty good job on explaining stuff, however I'm was wondering if someone could break it down even further.

445Eliptic curve is based on the algebraic structure of elliptic curves over finite fields

or

RSA is Based on difficulty of factoring a number which is the product of two large prime numbers

1,262■■■■□□□□□□Here is a SANs paper that goes into the math of Asymmetrical Cryptography:

1■□□□□□□□□□Conceptual? Doing the math yourself? Writing your own code? Designing a new method?

The above SANS paper is pretty good overview.

There are articles that will explain the algorithms in more detail and books that will show how to write the code (big number arithmetic).

If you have 6 weeks to spare, I recommend this Coursera Crypto course which covers RSA about halfway in.

For some reason, I'm really fascinated with the subject of Cryptology.
