DEVELOPMENT OF AN INTERACTIVE CRYPTOGRAPHY GAME USING MATLAB: THE CASE OF THE TWISTED CAESAR CIPHER
Keywords:
Game based learning, Critical thinking, Cryptography, Active learningAbstract
Classical cryptography is often taught as part of discrete mathematics in Computer Science and Information Technology. However, teaching abstract mathematical concepts in cryptography can be challenging in traditional classroom settings due to its abstract nature and algorithmic complexity. Therefore, this paper presents the development of an interactive, game-based learning tool aimed at enhancing the understanding of classical cryptography. The project centres around the Caesar Cipher Twisted, a modified version of the traditional Caesar Cipher. The game employs a progressively structured approach. It has six levels where each of the levels introduces complex variations of the encryption and decryption processes. As such, in level 6, the cipher text is in the form of numbers without separation. The level introduces non-standard Caesar Cipher variant which is a creative twist that goes beyond the classic cipher. The questions in each level are intended to stimulate critical thinking, logical reasoning, and pattern recognition. By utilizing MATLAB's GUI capabilities, the game offers a user-friendly environment suitable for students and educators alike. Preliminary feedback suggests that the game facilitates improved engagement and comprehension among students. This study highlights the pedagogical potential of integrating technology and game based learning in the classroom, particularly in abstract topics such as cryptography. This work also demonstrates the value of combining classical mathematical concepts with modern educational tools to foster active learning and conceptual understanding.
