2) Alice and Bob is using El Gamal public key consists of three parameters (p, g, B). Where B is the Public key of Alice. Common information and Alice private given as shown in the Table below. No Alice Common to both Bob Alice and Bob p= 13, g= 2 a Say b=3 B k=4, M=2 C = (C1, C2) b Proof C is message M= 2 a. Calculate the public key B that Alice must share/ send to Bob b. Bob has to compute C1 and C2 for the Plain Text M=2. Let say Bob chooses a randomly generated number k = 4. Calculate the ciphertext C = (C1, C2) that Bob sends to Alice c. Proof that Alice really gets the exact plain text Bob sent to her
