OTE: In all the below questions, write down the complete description/calculation/encryption/ decryption procedures. Just writing the encrypted or decrypted text is NOT acceptable. Find the Cipher text using the following block diagram if the relevant information are as under: Plaintext: 1 0 1 1 1 0 1 0 [10] -1: Expansion Permutation Block: 231 4 32 11 00 1 1 Key: Permutation 3142 Block: S-Box: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0 14 4 13 12 15 1 0 15 7 3 14 2 13 11 8 3 10 6 12 5 9 0 7 3 8 10 50 1 10 6 12 11 9 5 2 4 1 14 8 13 6 2 11 15 12 9 7 13 3 15 12 8 2 4 9 1 7 5 11 3 14 10 0 6 13 Plain text 8 4 Left Right 4 4 Expansion Permutation 67 6 XOR+ Key 4 76 S-Box Permutation -4 XOR 4 -4 Left Right 4 +8 Cipher text Page 2 of 3
