"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. " - Cryptography diffusion
