    Errrm - so define the keyspace and how the original messages map onto the keyspace pages, and then the ciphertext pages and how the keyspace pages map onto the ciphertext pages *before* saying *pseudo-categorically* that they are the same size without prior correlation so that there is some understanding of the relationship between the encryption processes that describe the key relationships . . . *please*!

    Wait. If the pattern changes every time, wouldn’t it take an equally long amount of time for Bob to decrypt the message as Eve?
