Cryptography diffusion
WebThe simplest way to achieve both diffusion and confusion is a substitution-permutation network. In these systems, the plaintext and the key often have a very similar role in … 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
