2. Assume Bob sends an Elgamal encrypted message to Alice. Wrongly, Bob uses the same parameter i for all messages. Moreover, we know that each of Bobs cleartexts start with the number x1=21(Bobs ID). We now obtain the following ciphertexts
(kE,1=6,y1=17),
(kE,2=6,y2=25).
The Elgamal parameters are p =31,\alpha =3,\beta =18. Determine the second plaintext
