WebQuestion. The following ciphertext is encrypted using a monoalphabetic substitution cipher. Use the frequency analysis technique described in the lecture to decrypt this. Show the frequency of letters in the ciphertext and show your work. You can use different tools (with citing the source) to find the frequency of letters, or write your own code. WebWith a ciphertext -only attack, the attacker has access to the ciphertext, but not the contents of the plaintext. The patterns and context of the message is used to derive the contents of the message. Frequency analysis has been used to break traditional ciphers using this method.

WebMay 4, 2016 · The ciphertext clearly does not need to be secret. And the IV serves as the ciphertext input for the first block. If the first block were not secure with a known IV, the second block would not be secure with known ciphertext, and ciphertext is known. So if the second block is secure, the IV need not be kept secret. – David Schwartz
