THE IMITATION GAME (Alan Turing defeat ENIGMA machine in World War II)

Yesterday finally I watched THE IMITATION GAME (Alan Turing defeat ENIGMA machine in World War II)

Alan Turing create the Turing test, that’s a test of a machine’s ability to exhibit intelligent behaviour equivalent to, or indistinguishable from, that of a human. In the original illustrative example, a human judge engages in natural language conversations with a human and a machine designed to generate performance indistinguishable from that of a human being. The conversation is limited to a text-only channel such as a computer keyboard and screen so that the result is not dependent on the machine’s ability to render words into audio. All participants are separated from one another. If the judge cannot reliably tell the machine from the human, the machine is said to have passed the test. The test does not check the ability to give the correct answer to questions; it checks how closely each answer resembles the answer a human would give.

But the movie focusses about defeating ENIGMA machines.

A-Three-Rotor-Enigma-Cipher-Machine

Enigma machine was any of several electro-mechanical rotor cipher machines used in the twentieth century for enciphering and deciphering secret messages. Enigma was invented by the German engineer Arthur Scherbius at the end of World War I. Early models were used commercially from the early 1920s, and adopted by military and government services of several countries, most notably Nazi Germany before and during World War II.

In a resume Alan team that from 6:00 am to 11:59 pm to try decrypted that day code and exist more than 159.000.000.000.000.000.000 possible combinations, and in my humble option the first right decision has been is necessary a machine to break a machine.

CHRISTOPHER is the name Alan giving to is machine and we can say is that’s an approach to IA we see today in project has WASTON from IBM.

Frist tries has been a frustrating, because no one know who much time CHRISTOPHER going to been to decipher a code and after week don’t show any positive result.

Now can a several isolated and lucky circumstances that Alan Turing merge and idealize a new approach, why don’t teach CHRISTOPHER to understand a sequence that happen all day and they already know part of the message.

Again the weakness has been a German soldier that forgets to change encryption and always use the same, maybe if this weakness isn’t exploited, CHRISTOPHER going to never a lot more time…

Seeing the movie I don’t stop thinking that Alan Turing (the hero of World War II) has need a hacker and exploited a weakness of the system (in this case the human)

Kevin Mitnick in is particular way, perform social engineering to exploit the weakness of human.

Today phishing attacks have more success that exploiting systems.

 

Now came the question, is simply defeat the system of the weakness of the humans?
