You are Alice. You have agreed with your friend Bob that you will use the Diffie-Hellman public-key algorithm to exchange secret keys. You and Bob have agreed to use the public base g = 5 and public modulus p = 809. You have secretly picked the value SA = 13. You begin the session by sending Bob your calculated value of TA. Bob responds by sending you the value TB = 609. What is the value of your shared secret key? Can you guess Bob's secret value SB and what it would be? Show each step of your calculations
