Which one of the following statements is INCORRECT (False) regarding modes of operation of a strong block cipher like AES? a. One of the modes of operation of AES provides neither confidentiality nor authentication for a plaintext that is longer than a block-size. b. Using ECB mode of operation can lead to a ciphertext that is longer than its plaintext even for plaintexts that are longer than one block. c. ECB mode of operation can provide both confidentiality and data integrity provided that the plaintext message is shorter than a block length. d. Using CBC mode of operation can lead to a ciphertext that is longer than its plaintext even for plaintexts that are longer than one block. e. One of the modes of operation of AES provides both confidentiality and authentication for a plaintext that is longer than a block-size
