often colloquially we hear this idiom as "gibberish diploma."Meaning phraseologism usually is: something incomprehensible, meaningless, at least for the speaker.In some cases, it is used?Here's a simple example: "For me, logarithmic equations - is like gibberish diploma."Note that the metaphor is often used in conjunction with an indication of the person to whom something is written or said remains unclear.Consequently, gibberish - is something tricky for the uninitiated, the profane.After logarithmic equations are not a mystery to the real experts.However, the most interesting is that this expression - not fiction, not witty.What is this?Let's examine this issue in more detail.
Why cryptography?
not known exactly when there was writing, but most of all, the need to hide the meaning of the text was born immediately after the appearance of characters and letters.Not everyone wanted to unauthorized person could read the notes.For the pouch cryptography, ie, cryptography was a vital necessity.For courier, messenger could intercept a variety of security services of hostile states.Many nations in ancient times had their own encrypted codes.The ancient historian Herodotus mentions letters, understandable only to the addressee.And the Spartans in the fifth-sixth centuries BC there was a device for encryption "label Aeneas" and a special decoder "Stsitala."Julius Caesar uses its own secret alphabet.There was a cipher and the Slavs.It was called "gibberish diploma."
original code
mainly ancient Cryptography (from the Greek words "crypto" - hidden, and "graphy" - description) based on the letters interchanged.No exception has been and Slavic gibberish diploma.The value of it and are easy to open.We divide all the consonants in the Russian alphabet in half (the "d" and "s" does not take into account).We make elementary plate: top write in order the first half liter and below - the other, but only in reverse.When writing letters simply change the text.Thus, the "b" becomes "u", "e" to "i" and "p" in "m".Vowels and omissions, and the soft sign with "th" remain unchanged.This encryption method is called litoreya.The appearance of the first letters of gibberish historians date the end of the thirteenth century.
Imperfection Slavic cryptography
What gibberish letter easy to decipher, easy to guess.The number of letters in the word and vowels, which abound in the Russian language, make it possible to solve everything else.Therefore litoreya or symmetric cipher like gibberish called diploma in a scientific way, had always complicated to be effective.So after some time there was a secret writing "tricky."She had several options, among which was "tsifir."Letters correspond to the number, and have them make simple arithmetic operations - for example, added a certain constant number key.In this cryptography it was hidden and vowels, which complicates the task of party cryptanalysts.However, the Russian language is that it has often used the letters.They also advocated by the strings pulling that could easily unravel the whole ball.
Departure from littres
gibberish diploma in Russia used the first Greek letters, then tried to go to the Latin alphabet, but these tricks have not made it more tricky.With the rising of the throne of Ivan the Terrible and the increasing influence of Russia in world politics the issue of encryption of letters to the ambassadors was the edge."Zateynoe letter", which was used Podyachev Chamber of secret affairs, had at its core the key that memorized.Sometimes, whole words or syllables are replaced by bizarre icon symbol.Before we reached the ABC special, elaborated Patriarch Filaret.Alexis and his son Peter I also had before it the ABC of fictional characters.But on the other hand, it is too difficult fonts are ineffective in wartime.Depeche came many, and the military, in virtue of their profession are not always up to the task of deciphering.
solid chemistry
Since the war with the Swedes simple gibberish diploma provided "exceedingly easy to disassembled" and was tricky too tough generals, Peter the Great had recourse to the help of chemistry.A letter to the Russian ambassador to the king of Sweden."I send you three sklyanitsy.- Clarifies the emperor.- What you want to write secret, write with ink from the first jar.Then paint on top of the second bottle nakalyakal anything.The third fluid is used to that, how to get a letter from me, then wipe the paper - unnecessary come and tread the secret. "It is clear that there cryptanalysts reagents should get (or make them yourself), as the hidden becomes manifest.So Peter did not refuse, and other encryption methods.While Napoleon was very common so-called "code book".The sender and recipient were available two copies of a single book.In this case, the correspondence consisted of numbers that indicates the page, row and place the words in this book.
gibberish diploma: phraseologism
cryptography This practice was so common that it has become ideomaticheskim expression.Litoreya spawned a number of set phrases."Tara bars" means empty, meaningless conversations.Why is that?First, to bring down the cryptanalysts confused, often resorted to the method of "dummies."In the middle of the text inserted meaningless words, a simple cluster of letters.Secondly, the coded message left very common in the Russian language the letter "a", changing only the consonants.As a result, often go "containers bar."There is this expression and another, quite different from the value of idle talk.We have already mentioned about it.Gibberish, gibberish or diploma - is something senseless and incomprehensible to the uninitiated.In this metaphor, there are synonymous.This "book with seven seals" and "Chinese puzzle".
