COMP41280 Introduction to Information Security

Academic Year 2021/2022

This course provides an introduction to the theoretical and practical underpinnings of information security. Information security is a broad field, encompassing all forms of information protection. The main focus of this course is on cryptographic primitives, an important set of tools on which information security usually relies. We start by studying the fundamentals of cryptography, and then we go on to address practical cryptography, digital signatures, and authentication. The course ends with a review of the fundamentals of digital data hiding (watermarking and steganography) and digital forensics, which are fields unrelated to cryptography.
