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. WebDec 6, 2024 · In 1949, Claude Shannon first proposed the ideas of confusion and diffusion in the operation of a cipher. Confusion is the property of a cipher whereby it provides no clue regarding the relationship between the ciphertext and the key. Given plaintext p, a sequence of keys k1, k2, . . . ki and the corresponding ciphertexts are obtained using ...
