I want to obtain the plaintexts.
They were encrypted with the same nonce and key in the counter mode using the AES block cipher. The plaintexts are English sentences.
I guess the first word is 'the' in sentence2. When I found the 'Enc' in the sentence2. I thought the first word of sentence2 is 'Encrypted'.
I know that the keystream is combined the nonce and the counter value in the Counter Mode. But, I don't know what should I do after this.
I can't guess the word anymore. How can I know the nonce and obtain full plaintexts??
Any help will be really helpful to me!! Thank you!
