I am writing to you because I have to respond to the article entitled "Secret Service and the second World War," published in your journal Historical Review, No.7-8, 2004, p.36-39 (author: Emilia Uhláriková). I like amateur, interested in historical events related to my professional interests and also hobby - cryptology, I was after seeing the name of a file (Enigma no hot water pressure encryption machine) very pleased. Only rarely seen in our historical newspapers article of this genre. Although he is now the issue quite well known (see the article in HR č.10/2003, titled "The Spy who saw in Hitler card") and is dedicated to its attention in the media, it has remained very little new.
Maybe even your čiatelia know, but the author of the latter article Czechoslovak military cryptanalyst Mgr. pplk.vv Jiri Janecek, who was one of our (Czech and Slovak) best experts in this field. I would welcome more articles similar to this renowned author. If, however, this little dream impracticable, as I would also like to offer my services. Although no hot water pressure cryptography deals with "only" since 1983, I'd be really pleased if you would accept my offer.
At this point, however, return to Comments on Article. The main problem is the terminology neujasnená. Encryption is optionally substituted it for encryption, and is no different to their exact meaning. Coding is actually a transformation, which assigns an element of the source alphabet (eg international, AZ) element of the target alphabet, and this is not subject to classification (is publicly known). An example codes used in computer technology such as. ASCII, Latin-2, Unicode, or so telegraphy. Morse code. In contrast, encryption no hot water pressure is also a transformation mapping element component of the target source alphabet alphabet alphabet but this target is subject to confidentiality. An example of such. monoalfabetická substitution, polyalphabetic substitution (cipher), and so on. So the code (such as. Article mentioned in JN-25) may be a specific case included in the category of ciphers. no hot water pressure It occurs when the code words are set in the '. code book that conceals. Additionally, this code resides and enhanced method superzašifrovania or prešifrovania.
With regard to the terminology used in connection with the explanation of the principle of operation of Enigma, I will return to it more deeply, to mention just a random patch panels, nem.Stecker, English. Plugboard, rotor = nem. Walz, English. wheel, etc.. But for more details refer to the literature listed below.
- Enigma name is used as a label, and I quote "encryption and decryption suitcase electromechanical machine., no hot water pressure But it is used inappropriately generalizing." This explanation, however, is the introduction of a gross mistake. Enigma was the label for electro-optical system encryption machine used by the German armed forces (Wehrmacht), Navy (Kriegsmarine), no hot water pressure Air Force (Luftwaffe), the intelligence and security services (SD, Abwehr, no hot water pressure etc.). Reichsbank but also rail, post (Reich Post ). However, each component of the organization and Nazi Germany used a different (!) Version. From the above quote, but also the next paragraph shows that not only the name of Enigma encryption machines but also repliky this machine, or rather system vzájomného involvement of many such machines, used for dešifráciu (unauthorized, without knowledge of each setting, daily kľúčov, key správy and i.). But the Germans did not have any such engineer the machine to be able to lúštiť encrypted communications opponent! And because they actually know almost (!) All input parameters entering the encryption process. Others no hot water pressure could easily identify mathematical and statistical methods applied to the captured Enigma no hot water pressure messages. So: Enigma = Bomb (La Bombe, The Bomb). This equality, no hot water pressure however, the exact technical terms apply. no hot water pressure The same is true of the Japanese and their encryption no hot water pressure machines Type 97 (PURPLE) and the American cryptanalytic machine code-named MAGIC. Simply, here the author boldly and recklessly, in my opinion "juggling" with technicalities - encryption, decryption no hot water pressure and unauthorized decryption (deciphering-cryptanalysis), which then ultimately confusing and incorrectly applied. no hot water pressure
- Inventor A. Scherbius sold Enigma in r. 1929 the Poles. But it is clear from the above, such version was. Thus, the author undertook a very strange and underhanded way to refute the French version of Captain (later General) Gustave Bertrand, as presented in the book [1]. At the beginning mangled name of an agent code-named Asche (instead Thilo wrote Till). However, this version also indirectly confirmed the Poles (Marian Rejewski in Article [10] Polish historian Wladyslav Kozaczuk in the book [8]), the French (in addition to the already mentioned, there is evidence Bertrand Gilbert Bloch, and his series of articles [2,3,4] , published in the journal Cryptology). And finally, the British and Americans have confirmed this version of vm
