| Summary: | For students who are taking courses on Cryptography, they will be required to learn about the different types of cryptographic algorithms. One of the most common cryptographic algorithms is the Advanced Encryption Standard (AES). The AES algorithm consists of two main components: Key Expansion, followed by Processing Rounds; each round consists of four processing steps: SubBytes, ShiftRows, MixColumns, AddRoundKey. To fully understand how AES works, other than the components of the algorithm, it is also essential to learn about Galois Field (GF) polynomial arithmetic as a mathematical prerequisite, since the AES operations are performed in GF(2^8).
The project aims to create a visual and interactive demonstrator for the purpose of a learning tool for students, by decomposing the entire algorithm into separate components and showing how each component works. In addition, the demonstrator should also show the stepwise computation of the GF polynomial arithmetic so that users are able to understand the mathematical concept behind the algorithm better. The demonstrator was created using Jupyter Notebook, with explanations and demos implemented using widgets, and rendered as a web application for increased interactivity. |
