"WebSep 8, 2024 · In cryptography, confusion refers to making the relationship between ciphertext and the symmetric key as complex as possible. Diffusion is used to dissipate the statistical structure of plaintext over the bulk of ciphertext. What this means is that a single bit change on the plaintext should at least change half of the resulting ciphertext. " - Cryptography diffusion
