So in this picture, you see that rotor four is spinning faster and rotor two is spinning slower.

This is the rough idea behind rotor encryption machines.

If you can't, hit rewind and watch that part again.

So to understand that, we have to rewind 75 years.

First, we choose from 1 of 6 possible rotor orderings.

Then we select an initial position from the rotor sequence.

And there's a rotor there that this motor is spinning.

And if you manipulate the speed of this rotor, you are actually able to crack the rotor and eventually even have the centrifuge explode.

And the other way around, if you increase the speed of rotor three and decrease the speed of rotor one, then the robot pitches forward.

This destroyed the uniform distribution of the initial rotor position, and after repeated observations, it allowed the allies to reverse engineer the rotor wirings completely.

Let's rewind to before the zit, to before Justin even sees his crush.

Understand that each rotor position is equivalent to a location in the sequence.

When the rotor advanced, an entirely new path was defined for each letter.

If we rewind to the world before World War I, things were very different.

So we were able to associate the small digital warhead with the rotor control.

Each rotor wheel had electrical contacts on either side with a maze of wirings within.

The rotor is that moving part within the centrifuge, that black object that you see.

Now, the state of the art technology of the time was called a rotor encryption machine.

So at each rotor position, there's an electrical path from every input letter to every output letter.

Now we're going to rewind and just focus on the chromosomes, and look at its structure and describe it.

To solve this problem we need to rewind and it doesn't require any government subsidies yay! or fancy appliances.

Let's back to the previous scene when I looked for my cards. rewind from bref, a famous short TV series

It was an electromechanical rotor machine invented by a German engineer at the end of the World War I.

You wish to make sure that a helicopter can be recognized, no matter what angle it's rotor blades currently have.

The security of rotor machines depends on both the size of this key space, and the randomness of the key setting.

The time that has passed will never come back again, while each clip of a film records every second, and enables us to rewind time!

If the operators had instead rolled dice to decide their initial rotor positions, the starting points in the sequence could have been uniformly distributed.

They were to select a random initial position of each rotor before communication began, and a very simple mistake was made by some fatigued operators.

For example, some changes they made were to add a fourth rotor wheel, and increase the number of possible rotors you could put into the machine to 60.

For a given messaging crypt, the Bombe could scan through all possible rotor positions and orders, in order to find possible key settings in a matter of minutes.

Now wth that said, let us rewind back to 1970, when Chile was having an election for president and they have their election and it's considered a fairly free and fair election.
