Answer 2

EBC process should not be used for encryption for small box sizes. (Option C).

• Electronic Cipher (refer to the word mentioned in the question) Book (ECB) is a straightforward manner of operation using a block cipher that is commonly employed with symmetric key encryption.
• It is an easy method of processing a sequence of message blocks.
• The supplied plaintext is divided into many blocks.
• Using the encryption key, the blocks are separately and independently encrypted (ciphertext).
• As a consequence, each encrypted block may be decrypted separately.
• Although ECB may allow a distinct encryption key for each block type, it should not be utilized for tiny box encryption.
• As a result, option C is right.
