Question: We will consider Diffie - Hellman key exchange. Alice and Bob have agreed to use the one - way function x 9 9

 We will consider Diffie−-Hellman key exchange. Alice and Bob have agreed to use the one−-way function x 99x ((mod 17)which they will use to set up a key which only they know. Alice chooses the secret number 5, and Bobs secret number is 7. Use the rules of modular arithmetic to compute the key from this data, showing your working.
