प्लगबोर्ड इसके अंग्रेजी अर्थ का उदाहरण

The grill method tests were also complicated by the plugboard settings.

In contrast, the clock method involved simple tests that were unaffected by the plugboard.

They may not know the other secrets of the daily key such as the plugboard setting, the ring settings, the rotor order, or the initial setting.

A plugboard interchanged additional characters.

Surprisingly, the Poles cracked the message keys without learning the substantial secrets of the daily machine settings: the plugboard settings, the rotor order, the rotor positions, or the ring settings.

They also did not know the plugboard settings.

By 15 July 1928, the German Army (Reichswehr) had introduced their own version of the Enigma—the Enigma G; a revised Enigma I (with plugboard) appeared in June 1930.

In addition, there was a plugboard that did some additional scrambling.

The number of possible different plugboard wirings (for six cables) is:.

the plugboard connections (Steckerverbindung).

Without knowing the plugboard settings, the rotor positions, the ring settings, or the ground setting, he could solve for all the daily message keys.

The end result was that without knowing the Enigma's plugboard settings, the rotor positions, or the ring settings, Rejewski determined each of the permutations A B C D E F, and hence all of the day's message keys.

After learning the rotor wirings, the Poles used the permutations to determine the rotor order, plugboard connections, and ring settings through further steps of the grill method.

Rejewski modeled the machine as permutation made from permutations of plugboard (), the wiring from the keyboard/lamps to the rotors (), the three rotors (), and the reflector ().
