Public Key Cryptography
In the early 1970s, Diffie worked with Martin Hellman to develop the fundamental ideas of dual-key, or public key, cryptography. They published their results in 1976—solving one of the fundamental problems of cryptography, key distribution—and essentially broke the monopoly that had previously existed where government entities controlled cryptographic technology and the terms on which other individuals could have access to it. "From the moment Diffie and Hellman published their findings..., the National Security Agency's crypto monopoly was effectively terminated. ... Every company, every citizen now had routine access to the sorts of cryptographic technology that not many years ago ranked alongside the atom bomb as a source of power." The solution has become known as Diffie–Hellman key exchange.

Famous quotes containing the words public and/or key:
“The last public hanging in the State took place in 1835 on Prince Hill.... On the fatal day, the victim, a man named Watkins, peering through the iron bars of his cell, and seeing the townfolk scurrying to the place of execution, is said to have remarked, Why is everyone running? Nothing can happen until I get there.”
—Administration for the State of Con, U.S. public relief program (1935-1943)
“At the last, tenderly,
From the walls of the powerful fortressd house,
From the clasp of the knitted locks, from the keep of the well-closed doors,
Let me be wafted.
Let me glide noiselessly forth;
With the key of softness unlock the lockswith a whisper,
Set ope the doors O soul.”
—Walt Whitman (18191892)
