When used correctly, one-time pad encryption is unbreakable ... and British code-breakers revealed that some of the one-time pad material had incorrectly been reused by the Soviets (specifically, entire pages ...
... In connection with his WWII work at Bell Labs, Claude Shannon proved that the one-time pad cipher is unbreakable, provided the key material is truly random, never reused, kept secret from all possible ... Most ciphers, apart from the one-time pad, can be broken with enough computational effort by brute force attack, but the amount of effort needed may be ... This means it must be shown that no efficient method (as opposed to the time-consuming brute force method) can be found to break the cipher ...

Famous quotes containing the words pad and/or time:
“I have known the inexorable sadness of pencils,
Neat in their boxes, dolor of pad and paper-weight,
All the misery of manilla folders and mucilage,
Desolation in immaculate public places,”
—Theodore Roethke (19081963)
“Fair Hope! our earlier Heaven! by thee
Young Time is taster to Eternity.
The generous wine with age grows strong, not sour,
Nor need we kill thy fruit to smell thy flower.
Thy golden head never hangs down
Till in the lap of Loves full noon
It falls and dies: Oh no, it melts away
As doth the dawn into the day,
As lumps of sugar lose themselves, and twine
Their subtle essence with the soul of wine.”
—Abraham Cowley (16181667)
