Which of the following are NOT operating modes of the DES encryption algorithm? A) CBC B) ECB C) CFB D) OFB E) CBE (Ans- e. DES has four modes of operations: CBC - Cipher Block Chaining. In CBC mode, each plaintext block is XORed with the previous cipher text block and then encrypted. ECB - Electronic Code Book. In ECB mode, each plaintext block is encrypted independently with the block cipher. CFB - Cipher Feedback. In CFB mode, the previous cipher text block is encrypted and the outpu...
