WebMar 14, 2024 · DES is based on the two essential attributes of cryptography including substitution (also known as confusion) and transposition (also known as diffusion). DES includes 16 steps, each of which is known as round. Each round implements the steps of substitution and transposition. DES is a symmetric cryptosystem. WebThe DES algorithm, also known as the Data Encryption Standard, is a block cipher for encrypting a block of 64-bit plain text with a 56-bit key, resulting in a 64-bit ciphertext. It relies on two cryptographic techniques: substitution and transposition, which are carried out over 16 rounds.
