Course Overview

The process of encrypting and decrypting information forms the basis of much computer, device and network security. Cryptography is designed and used to protect the confidentiality, integrity and authenticity of information. From the very beginnings of computing, and throughout the industry’s evolution, the establishment of policies, guidelines and laws has shaped the disciplines of information security and organisational resilience in profound and, often, unintended, ways. 

In this course learners will be introduced to the concept and history of cryptography, and its subdisciplines (including cryptology), and how cyber-enabled networks and devices have their communications security underpinned by cryptographic methods and sector standards. Learners will explore methods of attack, including side-channel, additional encryption methods and escrow principles and key. Learners will look at how businesses can deploy encryption to enhance their information security approaches.
