We often see mathematical material in an abstract manner, but behind formal theorems and rigorous proofs, we can find significant applications to the real world. One example which has become crucial to our daily lives is cryptography. When we access a bank account online or purchase an item electronically, we rely on some method of cryptography to ensure that our information is secure. In this talk, we present the RSA model for cryptography as built from concepts involving prime numbers, factorization, and other fundamental topics in number theory.
