Question: 5. (a) Compute the key shared between Alice and Bob when Alice and Bob use DHKE with parameters p = 467, = 2 and secret

5. (a) Compute the key shared between Alice and Bob when Alice and Bob use DHKE with parameters p = 467, = 2 and secret keys a-3, b = 5. (b) Suppose Alice encrypts and sends miessage x = 33 to Bob using El-Gamal encryption scheme. Suppose the parameters chosen are p = 467, = 2 and kpr,B = d = 105, Alice chooses i = 213 for computing the ephemeral key. What is the ciphertext
