comment Current mathematics theory used in cryptography/coding theory
I always just called it prime theory. Though, of course, if prime theory did exist it would most definitely be a subset of number theory. :) Thanks for clarification.

comment Taking advantage of one-time pad key reuse?
Well, what you are doing is using a randomly generated key and combining it with the plaintext to form the ciphertext. If it is used more than once, then you could find out how the key and plaintext are being used to form the ciphertext, then exploit this to deduce some letters? Further, use common cryptanalysis techniques to solve (letter frequency, bigrams, etc...)? This might help: cs.utsa.edu/~wagner/laws/pad.html
