Cryptography diffusion

WebIt is previously predominant algorithm for the encryption of a electronic data.It was highly influential in the advacement of modern cryptography in the academic world.Developed in the early 1970s at IBM and based on an earlier design by Horst Feistel. Data Encryption Standard-DES is a feistel cipher-Block Length is 64 bit-Key Length is 56 bit 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.
