Question

Project: The ciphertext AUACCEE results from applying the encryption scheme P longmapsto 3P^2 - P + 2 to a certain 7-letter text. The trouble with this encryption scheme is that it is not one-to-one. It encrypts more than one letter in the same way. For example, both G and T get encrypted as A. In spite of this liability, determine what the original message was. Discuss the problem in class. Refer to [KOB] and [WAS] for further details. Project: Produce a digraph encryption scheme that is not one-to-one. Use it to encrypt the message One for the money. What ciphertext results? What would be another plain English message that encrypts to the same ciphertext? If you had to decrypt the message, how would you distinguish these two originals? See [KOB] and [WAS].

Explanation / Answer
