Summary of "AES Round Transformation"

The video focuses on the AES round transformation in encryption and decryption processes. It explains the four transformations used in each round: substitute bytes, shift rows, mix columns, and add round key. The importance of confusion and diffusion in encryption algorithms is highlighted, with a focus on substitution and permutation. Each transformation function is explained in detail, including how they alter the input state array. The session aims to help learners understand the AES encryption and decryption process thoroughly.
