I'm trying to understand the concepts behind RSA right now. From what I've learned so far, it's pretty much all about a one-way function with a trapdoor: Raising the message to the e'th power modulo N, where the factorization of N is kind of the trapdoor.
But on the other hand, I've got the one-way function where I multiply two big primes to receive N. So can one talk about two different one-way functions where the first is used to receive the trapdoor of the other?
