Difference between Confusion and Diffusion

WebNov 4, 2024 · Confusion and diffusion are two important cryptographic properties [ 1 ]. The confusion is responsible for making the relation between key and ciphertext as complex as possible, and the diffusion is to spread the internal dependencies as much as possible. Both concepts are very important for the overall security and efficiency of the ciphers.

WebConfusion and diffusion aren't attributes provided by DES, but rather the building blocks of creating a cipher like DES. In the case of DES, the confusion step is the S-box substitution, while the diffusion step is where the output of the S-boxes is rearranged according to the P-box permutation rules. See Wikipedia: DES for the actual details.
