academic.csuohio.eduFig. 6.1 Encryption and decryption with DES At the encryption site, DES takes a 64-bit plaintext and creates a 64-bit ciphertext; at the decryption site, DES takes a 64-bit ciphertext and creates a 64-bit block of plaintext. The same 56-bit cipher key is used for both encryption and decryption. 6.2 DES STRUCTURE

engineering.purdue.edu3.2.2 Decryption in Ciphers Based on the Feistel Structure As shown in Figure 3, the decryption algorithm is exactly the same as the encryption algorithm with the only difference that the round keys are used in the reverse order. The output of each round during decryption is the input to the corresponding round during encryption
