Multiple choice

A cryptographer analyzes an encrypted message and notices a recurring pattern in the sequence of characters. What might this pattern reveal?

  1. A weakness in the encryption algorithm

  2. A hidden message embedded within the code

  3. A clue to the identity of the sender

  4. A random coincidence with no significance
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The cryptographer's observation of the recurring pattern in the encrypted message suggests that there may be a weakness in the encryption algorithm that could be exploited to decipher the message.
