Your digaram of a Feistel cipher
I reverted your edit, because your diagram is wrong. Either you describe a cipher with n rounds. Then the round keys have indices from 0 to n-1. and the ciphertext blocks have indices n. In this case the text needs to be changed too. Or you describe a Feistel cipher with n+1 rounds. Then the round keys should have indices running from 0 through n and the ciphertext blocks have indices n+1. 81.62.73.125 (talk) 17:03, 12 September 2011 (UTC)
- File:Feistel cipher diagram.png also have n+1 rounds + the text says: , whifh mean n+1 rounds. 87.69.235.248 (talk) 17:43, 12 September 2011 (UTC)
