In the Vigenere cipher, unlike in Ceasar cipher, the displacement involved for each character is different. The sequence of displacement is decided by a keyword, which is known to both the ...

The aim of this paper is to trace the development of cipher-writing from the very simple devices of the Ancients to the so-called Chiffre Indéchiffrable, generally called the Vigenère Cipher. The ...

In 1854, Sir Charles Wheatstone invented the cipher known as "Playfair," named for his friend Lyon Playfair, first Baron Playfair of St. Andrews, who popularized and promoted the cipher. Its ...

Secret code or foreign language? For machines, it might not matter. Without any prior knowledge, artificial intelligence algorithms have cracked two classic forms of encryption: the Caesar cipher ...

Using the Vigenère cipher, with the code coming from a reversed video of Bill’s demise, fans figured out the message—leading many of them to believe that Bill’s statue was real.

Mozilla has launched Codemoji to teach people how ciphers work and the value of encryption in a world of mass surveillance.

Cipher-cracking AI isn't just for decoding encrypted data—new research shows it can make quick work out of translating human language. A team of researchers from the University of Toronto and ...

To break the Enigma code during the Second World War, British computer scientist Alan Turing developed a mathematical model to unlock the cipher faster than any human. Today, a group of University of ...
