Question: Alice is using a one - time pad on the alphabet Z 2 = { 0 , 1 } with addition modulo 2 . The

Alice is using a one-time pad on the alphabet Z2={0,1} with addition modulo 2. The key for this one-time pad is generated by a primitive 5-bit shift register. Eve intercepts the following ciphertext: 000110001011011. Her spies have informed her that the initial part of the plaintext is 1000111011. Decipher the full ciphertext. Show your working.
