1. Alice uses the one-time pad encryption scheme to send a message to Bob. They share a key k {0,1}. Eve has managed to learn that the parity of k is 1. That is Eiki (mod 2) = 1, where ki is the ith bit of k. (Put another way, Eve learns that k has an odd number of ls.) Eve sees a ciphertext c. What can she learn about the plaintext? 1.
