A plaintext r is encrypted using two rounds of the Baby Horst cipher introduced in class. The key is 5B, and the resulting ciphertext is 08 (a) Find the round state LiRi and the plaintext z = LoRo. (b) Give all possible choices of R that could have produced the sameR found in part (a), given that Lo and the key are unchanged.
