In his Histories, Polybius outlines the need for effective signalling in warfare, leading to the development of the square. Previously, fire-signalling was useful only for expected, predetermined messages, with no way to convey novel messages about unexpected events. According to Polybius, in the 4th century BCE, Aeneas Tacticus devised a hydraulic semaphore system consisting of mat… WebCaesar cipher, is one of the simplest and most widely known encryption techniques. the cipher alphabet is the plain alphabet rotated left or right by some number of positions. When encrypting, a person looks up each letter of the message in the 'plain' Deciphering is done in reverse. The encryption can also be represented using modular arithmetic
WebVIC cipher. The VIC cipher was a pencil and paper cipher used by the Soviet spy Reino Häyhänen, codenamed "VICTOR". If the cipher were to be given a modern technical name, it would be known as a "straddling bipartite monoalphabetic substitution superenciphered by modified double transposition." [1] However, by general classification it is ...
