Cryptography confusion and diffusion

WebConfusion and diffusion Confusion is focused on changing the symbols from the original message to a different one (for instance, substituting an “a” by a “6”). Notice that when we refer to a message, it can be text, audio, video, images, etc. Diffusion refers to the goal of encrypted symbols not having the same position as the original symbol. WebDiffusion is enforced using permutation/transposition. Ciphers must use both of them because either confusion or diffusion alone are not enough. I read that a substitution …

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.
