(a) Describe the steps of the Diffie-Hellman key exchange protocol to generate the shared secret akıka between Bob and Alice, where a = 5 is a primitive element modulo 23, ki = 5 and k2 = 8. (You do not need to verify that 5 is a primitive root modulo 23. Do the computations explicitly in Step 2 and Step 4.) (b) Alice then uses their shared secret as a key for a shift cipher to send Bob her favorite tv series and Bob receives the ciphertext ΖNK COXK. What is her favorite tv series?
