  1. Plaintext tiller was encrypted using one-time pad and the resulting ciphertext is KITLKE. Letter encodings are the following: e (000), h (001), i (010), k (011), l (100), r (101), s (110), t (111). What is the key?
  2. Consider the knapsack cryptosystem. Suppose the public key consists of (10, 15, 30, 7) and n=34. Assuming m=5, find the private key and encrypt the message M=13. Your answer should be a decimal number.
