The Enigma machine is a cipher device developed and used in the early- to mid-20th century to protect commercial, diplomatic, and military communication. It was employed extensively by Nazi Germany during World War II, in all branches of the German military. The Enigma machine was considered so secure that it was used to encipher the most top ...
[175] [176] The set of ten bombes consisted of a total of 144 Enigma-equivalents, each mounted on a rack approximately 7 feet (2.1 m) long 8 feet (2.4 m) high and 6 inches (150 mm) wide. There were 12 control stations which could allocate any of the Enigma-equivalents into the desired configuration by means of plugboards.
[4] [32] Kryptos was also featured in another of Dan Brown's novels, The Lost Symbol (2009). [2] A small version of Kryptos appears in the season 5 episode of Alias "S.O.S.". In it, Marshall Flinkman says he has cracked the code just by looking at it during a tour visit to the CIA office. The solution he describes sounds like the solution to ...
In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet .
The pigpen cipher uses graphical symbols assigned according to a key similar to the above diagram. [1]The pigpen cipher (alternatively referred to as the masonic cipher, Freemason's cipher, Rosicrucian cipher, Napoleon cipher, and tic-tac-toe cipher) [2] [3] is a geometric simple substitution cipher, which exchanges letters for symbols which are fragments of a grid.
Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized:kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία -logia, "study", respectively [ 1 ]), is the practice and study of techniques for secure communication in the presence of adversarial behavior. [ 2 ]
Bacon's cipher or the Baconian cipher is a method of steganographic message encoding devised by Francis Bacon in 1605. [1][2][3] In steganograhy, a message is concealed in the presentation of text, rather than its content. Baconian ciphers are categorized as both a substitution cipher (in plain code) and a concealment cipher (using the two ...
“The most important is the balance,” says Abe through a translator. “We say it’s the balance between stability and betrayal.” Stability in her sleek and swift pinstripe suits and easy ...
