Cryptography

Programme Overview

You will learn the fundamentals and mathematical methods that are central to cryptography. Topics covered will include details on various concepts such as asymmetric and symmetric cryptography, public-key encryption, message integrity, hash functions, block-cypher design and analysis, number theory and digital signatures for secure communication. In addition, you will gain knowledge of how these concepts can be implemented and secured by creating algorithms to encrypt information and other security measures for overall efficiency. At the end of the course, you will understand how to analyse commonly used cryptographic primitives, types of attacks, and cryptographic protocols for computer security systems by exploring different solutions and architectures.

Learning Outcomes
