Atbash (Hebrew: אתבש; also transliterated Atbaš) is a monoalphabetic substitution cipher originally used to encrypt the Hebrew alphabet. It can be modified for use with any known writing system with a standard collating order .
The Atbash Cipher was applied and out of "Sheshach" came the word "Babel". This is supposed to be confirmed by a reference to Jeremiah 51:41 , where Sheshach and Babylon are in parallel clauses. There seems to be no reason to doubt that Babylon is here intended by this name.
The simplest substitution ciphers are the Caesar cipher and Atbash cipher. Here single letters are substituted (referred to as simple substitution ). It can be demonstrated by writing out the alphabet twice, once in regular order and again with the letters shifted by some number of steps or reversed to represent the ciphertext alphabet (or ...
Temurah may be used to change letters in certain words to create a new meaning for a Biblical statement. The Hebrew alphabet is an abjad or consonantary alphabet. Techniques that applied to English will mostly transform sense into a nonsensical series of letters are more feasible in Hebrew.
600-500 – Hebrew scholars make use of simple monoalphabetic substitution ciphers (such as the Atbash cipher) c. 400 – Spartan use of scytale (alleged) c. 400 – Herodotus reports use of steganography in reports to Greece from Persia (tattoo on shaved head) 100-1 A.D.- Notable Roman ciphers such as the Caesar cipher.
All of the electromechanical machines used in World War II were of this logical class, as were the Caesar and Atbash ciphers and essentially all cipher systems throughout history. The 'key' for a code is, of course, the codebook, which must likewise be distributed and kept secret, and so shares most of the same problems in practice.
ROT13 is a special case of the Caesar cipher which was developed in ancient Rome, used by Julius Caesar in the 1st century BC. [1] An early entry on the Timeline of cryptography . ROT13 can be referred by "Rotate13", "rotate by 13 places", hyphenated "ROT-13" or sometimes by its autonym "EBG13".
Hugh J. Schonfield (1901–1988), [42] one of the scholars who worked on the Dead Sea Scrolls, argued in his book The Essene Odyssey that the word "Baphomet" was created with knowledge of the Atbash substitution cipher, which substitutes the first letter of the Hebrew alphabet for the last, the second for the second last, and so on.
