Alice and Bob have selected prime number p = 19 and a primitive root r = 2 for their Diffie-Hellman key exchange. Alice's secret exponent is a = 11, but Bob's secret is b = 13. Compute the message A = r* (mod p) that Alice sends to Bob, and also the message B = r (mod p) that Bob sends to Alice. %3D
