MATLAB Implementation of AES Encryption Algorithm

MATLAB stands as a powerful computational language with diverse applications ranging from data analysis and image processing to cryptographic implementations. The AES (Advanced Encryption Standard) implementation in MATLAB serves as an essential tool for data encryption and decryption operations, leveraging MATLAB's efficient matrix operations for cryptographic transformations. This implementation includes visual demonstrations that illustrate encryption effects through graphical representations, helping users understand the algorithmic flow of AES operations including byte substitution, row shifting, column mixing, and key expansion routines. The demo program serves as an ideal starting point for learners, providing runnable code examples that showcase complete encryption/decryption workflows with customizable parameters for different key sizes (128-bit, 192-bit, 256-bit). Accompanying PDF documentation delivers comprehensive theoretical background and practical implementation guidance, covering essential aspects such as S-box generation, key scheduling algorithms, and inverse cipher operations. These resources combine to form a complete reference package that supports both educational understanding and practical application development. Beyond basic functionality, this MATLAB AES implementation offers robust support for cryptographic research and development, featuring optimized code structures that demonstrate efficient handling of state matrices and round transformations. The package serves as a valuable resource for professionals and researchers working on secure data transmission systems and cryptographic algorithm analysis.
