- Key wheels - key rolls
With the beginning of the 20th Century saw a rapid development
in the encryption affairs. Using the then electro - mechanical
knowledge and skills in a number of countries encryption
machines were developed. The starting point of this development,
among other things was also the ever-growing demand for a secure
transmission of information in many areas of society. At the same time the development of mathematics and mechanics
had created the conditions for the creation of practical
electromechanical system. Thus it was natural that in all emerging industrial nations was
an almost parallel development. One of the best documented
systems today, which is under the name "Enigma" Enigma machine
became known. The development history, its continued development
and solving their "ENIGMA" who needs so encrypted information on
their operation, not be discussed here. Since they are present
in a number of publications, such as "Crypto Museum" in the
Netherlands and the "Crypto Machine" from Canada, very good
illustrations. They illuminate the, to date, given free
information. Especially in the "Crypto Museum" is a very wide
range of information, from the hardware to the theory and the
decryption. Note the fact that these systems are
electromechanical type and thus a rote conversion of the
individual elements was difficult to carry out. This "vulnerability" of the electro-mechanical systems can now
be tackled by the use of computer chips and the result of this
development, the "full cryptographic space" but this well-known
system are used.
Which cryptographic capacity is in this ancient method, they
will know when they read the "Mathematical Cryptology Enigma"
from the house of the NSA / USA.
