Study Notes
The Enigma Machine
- The Enigma machine was an electric-powered mechanical device that used rotors to encrypt and decrypt text-based messages sent over radio waves.
- It had German origins and was an important technological development during World War II.
- The device looked like a large square or rectangular mechanical typewriter.
- Each key press would move the rotors and record a seemingly random character that would be transmitted to other Enigma machines.
Encryption and Decryption
- The Enigma machine used a symmetric key algorithm, which is a special type of cipher that allows for encryption and decryption of a message using a single cryptographic key.
- Any Enigma machine with an identical configuration could read or “decrypt” messages sent from another machine with the same configuration.
History and Development
- The technology was popularized by a two-man company called Chiffriermaschinen AG based in Germany in the 1920s.
- The German military adopted the Enigma machine in 1928 to secure top-secret military messages in transit.
Limitations and Flaws
- A single compromised configuration log (or private key) could render an entire network of Enigma machines useless.
- Reconfiguring Enigma machines was a time-consuming process that required manual adjustments to the machine itself.
Configuration and Key Exchange
- Configuration logs had to be exchanged in person, as secure ways of sharing them remotely did not yet exist.
- Updates typically occurred on a monthly basis, and if a key was intercepted or leaked, all transmissions for the remainder of the month could be intercepted.
Modern Relevance
- The type of encryption used by the Enigma machine is still used today in software to secure data in transit, but with many improvements on the classic model.
- Modern key generation algorithms produce keys so complex that attempting every possible combination would take more than a million years.
Cryptography and Hacking
- The Enigma machine was a major milestone in securing remote communications and laid the groundwork for modern cryptography.
- The adoption of Enigma machines by the Axis Powers during World War II resulted in pressure for the Allies to develop encryption-breaking techniques, which led to the development of modern hacking techniques.
Marian Rejewski and the First Hackers
- Polish mathematician Marian Rejewski and his team reverse-engineered the Enigma machine and intercepted and decrypted Enigma machine traffic on a daily basis.
- They can be considered some of the world’s earliest hackers, as they intercepted and reverse-engineered encryption schemes to get access to valuable data generated by a source other than themselves.
