Describe briefly how Cipher Feedback (CFB) worksCipher feedback mode is a block cipher. It is similar to cipher block chain mode, it also makes use of theinitialization vector (IV). It uses the block cipher as a component for a random number generator. Thecipher text mode is encrypted and the output is XOR-ed with the current plaintext block to create thecurrent text block. The plaintext cannot be worked directly unless the retrieval of blocks from either thebeginning or the end of the cipher text. The XOR operation conceals the plaintext patterns.Discuss the similarities and difference ...
