Overview
The fundamental aspects of cryptography that support computer security, and key technologies used to build secure software systems.
The aim of this paper is to provide students with an understanding of the modern theoretical bases of cryptography and how it relates to computer security. The paper also explores a number of widely used computer security technologies.
