DES consists of 16 steps, each of which is called as a round. ,Data Encryption Standard - The Data Encryption Standard (DES) is a symmetric-key block ... DES uses 8 S-boxes, each with a 6-bit input and a 4-bit output. ... The round-key generator creates sixteen 48-bit keys out of a 56-bit cipher key. ,The Data Encryption Standard is a symmetric-key algorithm for the encryption of digital data. ... Decryption uses the same structure as encryption, but with the keys used in reverse order. ... There are three attacks known that can break the full 16 round,encryption and decryption (except for minor differences in the key schedule). The key length ... via an expansion permutation, combined with 48 bits of a shifted and permuted key ... ber that DES predates 16-bit or 32-bit microprocessor busses. ,Data Encryption Standard (DES) is a block cipher algorithm that takes plain ...
