Turing: Breaking Enigma Methodology (1939)
by Anonymous
Alan Turing chose to build an electromechanical machine (the Bombe) to crack Enigma rather than relying on purely mathematical analysis or captured codebooks. This automated approach could keep up with daily key changes.
Electromechanical Machine (Bombe)
1939-1940
year
Automated search through possible settings
approach
Could crack daily keys within hours
speed
Chosen — decoded thousands of messages, shortened war by years
outcome
Mathematical Analysis Alone
1939
year
Hand computation of key possibilities
approach
Too slow — key changed daily
speed
Insufficient alone — needed mechanical aid
outcome
Rely on Captured Codebooks
1939
year
Steal German code materials
approach
Fast when available, unreliable supply
speed
Used as supplement — not reliable enough alone
outcome
