Quizplus · Accepted Answer

A guessed plaintext attack relies on the attacker knowing or guessing the plaintext of the original message. Adding random numbers at the end of the message does not significantly change the message itself, so if the attacker correctly guesses the plaintext, they will be able to recover the original message regardless of the added numbers.
