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:
“Prose—it might be speculated—is discourse; poetry ellipsis. Prose is spoken aloud; poetry overheard. The one is presumably articulate and social, a shared language, the voice of “communication”; the other is private, allusive, teasing, sly, idiosyncratic as the spider’s delicate web, a kind of witchcraft unfathomable to ordinary minds.”
—Joyce Carol Oates (b. 1938)
“The secret of heaven is kept from age to age. No imprudent, no sociable angel ever dropt an early syllable to answer the longings of saints, the fears of mortals. We should have listened on our knees to any favorite, who, by stricter obedience, had brought his thoughts into parallelism with the celestial currents, and could hint to human ears the scenery and circumstance of the newly parted soul.”
—Ralph Waldo Emerson (1803–1882)
“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)
