- Suppose that you have intercepted the following ciphertext message from me, which you know to have been encrypted with a monoalphabetic substitution cipher: hkypdukidpdufbnkaopektpkktpdswtrgtsktpacfiwdt You are to perform a frequency analysis to retrieve the plaintext that I generated the plaintext from. Specifically:
- Create a frequency table from the ciphertext.
- Based on this, what would be the most likely ciphertext character that the plaintext character e maps to?
- The letter e is very often followed by the letter n, which itself is a very common character. Based on this, what ciphertext character is it most likely that n maps to?
