Why does the ADT stack not define a get( ) method?
What will be an ideal response?

Suppose you suspect that your session with a server has been intercepted in a man-in-the middle attack. You have a key, K, that you think you share with the server, but you might be only sharing it with an attacker. But the server also has a public key, KP , which is widely known, and a private secret key, KS, that goes with it. Describe how you can either confirm you share K with the server or
discover that you share it only with a man-in-the-middle. Also, be sure your solution will not be discovered by a packet sniffer. What will be an ideal response?
