Assume Bob sends an Elgamal encrypted message to Alice. Wrongly,Bob uses the same parameter i for all messages. Moreover, we knowthat each of Bob’s cleartexts start with the number x_1=11 (Bob’sID). We now obtain the following ciphertexts (k_{E,1}=6, y_1=17),(k_{E,2}=6, y_2=25). The Elgamal parameters are p=31,alpha=3,beta=18.Determine the second plaintext x_2. ______
