"U.S. Tells How It Found Soviets Sought A-Bomb: Discloses Clues That Led to Code-Breaking."

The American intelligence establishment today unveiled one of its oldest secrets: how a small team of codebreakers found the first clues that the Soviet Union sought to steal the blueprints for the atomic bomb in World War II. Using just brain power -- no computers, no stolen skeleton keys -- the cryptographers slowly cracked what was thought to be an unbreakable code.

service. The messages were like a jigsaw puzzle with a billion pieces -- all black. They had been double-coded by a system called a one-time pad -- a unique random code for each message, converting words to numbers in a pattern used only once. HOO_doo

Note Julius Rosenberg's code name was "liberal". The NSA said that the Soviets were using a one-time-pad. The implication is that sloppy encryption practice caused Soviet code clerks to sometimes reuse the random material thus converting the code into a code book system that could be read.
