Secret-key (symmetric) cryptography requires the initial exchange of a shared key in a manner that is private and integrity-assured. When done right, MITM attack is prevented. However, without the use of public-key cryptography, one may be left with undesirable key-management problems.

Famous quotes containing the words shared, secret and/or keys:
“The happiest two-job marriages I saw during my research were ones in which men and women shared the housework and parenting. What couples called good communication often meant that they were good at saying thanks to one another for small aspects of taking care of the family. Making it to the school play, helping a child read, cooking dinner in good spirit, remembering the grocery list,... these were silver and gold of the marital exchange.”
—Arlie Hochschild (20th century)
“it is best then that the buried word remain buried for we were intended to appreciate only its fruits and not the secret principle activating them to know this would be to know too much. Meanwhile it is possible to know just enough, and this is all we were supposed to know, toward which we have been straining all our lives.”
—John Ashbery (b. 1927)
“McCoy: That shark’s been following us ever since the surgeon died, waiting for the burial. Couldn’t I have a musket to shoot it, sir?
Fletcher Christian: Take the deck, McCoy. I’ll get the keys to the arms chest.
McCoy: Get two muskets, sir. I’d like to shoot that shark on board.”
—Talbot Jennings (1896–1985)
