2.7 When using the one-time pad with the key k = 0, we have Enck (m) = km = m and the message is sent in the clear! It has therefore been suggested to modify the one-time pad by only encrypting with k # 0 (i.e., to have Gen choose k uniformly from the set of nonzero keys of length ). Is this modified scheme still perfectly secret? Explain. 2.7 When using the one-time pad with the key k = 0, we have Enck (m) = km = m and the message is sent in the clear!
