Abstract. This paper explores the history and mathematics be
hind the RSA cryptosystem, including the idea of public key cryp
tosystems and number theory. It outline
Alternative Induction Theorems
We define the greatest common divisor and least common multiple of more than
two integers recursively. That is, we define them for two integers, and then we use
these re
Mathematical Induction
Let us now consider the possibility of proving that all positive integers satisfy a
certain property. Since there are infinitely many positive integers, we cannot
possibly check
The Logic behind the Proofs
In this section, we go over the arguments we used to prove the statements of the
previous two sections. Note that we do not need to take a course to understand an
argument.
The Greatest Common Divisor
In the previous section, we considered the divisors of a single integer; in this
section, we study the divisors of two integers.
Definition 1.34. For a, b Z, an integer c i
Addition and Multiplication Axioms of Integers
In this section, we introduce proofs that involve addition and multiplication of the
integers. We are all familiar with the concepts defined in this unit
The Least Common Multiple
We now turn our attention to the multiples of pairs of integers.
Definition 1.46. For any integers a, b an integer m is a common
multiple of a and b if a| m and b| m; that is
The Fundamental Theorem of Arithmetic
We dedicate this section to proving the Fundamental Theorem of Arithmetic,
another theorem we can trace back to Euclids Elements. It explains the importance
of th
Finishing This Unit
1. Review the objectives of this unit and make certain that you are able to meet
all of them.
2. If there is concept, definition, example or exercise that is not yet clear to you,
Order Axioms of the Integers
In this section, we will freely use the results reached in the previous section,
including those in the exercises. That is, everything we learned about the integers in

Divisibility
In this section, we introduce the divisibility, prime numbers and the Division
Algorithm. Our focus is on understanding these concepts and the proofs that
establish the properties of divi
