WebNov 8, 2024 · This way of encrypting the plaintext twice does not double the strenght of the encryption. This is very similar to the classic Triple DES. This is vulnerable to the “meet in the middle attack” which is possible if we have known plaintext and ciphertext pair. “Guessing” the plaintext WebJun 25, 2015 · The CTR mode of operation for block ciphers makes a stream cipher out of a block cipher. Since stream ciphers work in a way that they generate a keystream and XOR the keystream with the plaintext to produce the ciphertext: plaintext XOR AES-CTR (nonce, key) = ciphertext. The XOR operation works in a way where XORing x with a key k twice …
