Solitaire (cipher) The Solitaire cryptographic algorithm was designed by Bruce Schneier at the request of Neal Stephenson for use in his novel Cryptonomicon, in which field agents use it to communicate securely without having to rely on electronics or having to carry incriminating tools. [1] It was designed to be a manual cryptosystem ...
The Princess of Soubise playing solitaire, 1697. Peg Solitaire, Solo Noble, Solo Goli, Marble Solitaire or simply Solitaire is a board game for one player involving movement of pegs on a board with holes. Some sets use marbles in a board with indentations. The game is known as solitaire in Britain and as peg solitaire in the US where 'solitaire ...
Step-by-step process for the double columnar transposition cipher. In cryptography, a transposition cipher (also known as a permutation cipher) is a method of encryption which scrambles the positions of characters ( transposition) without changing the characters themselves. Transposition ciphers reorder units of plaintext (typically characters ...
VIC 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 ...
t. e. In cryptography, a substitution cipher is a method of encrypting in which units of plaintext are replaced with the ciphertext, in a defined manner, with the help of a key; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth. The receiver deciphers the text by ...
The key concept in solitaire games is the creation of a simulated opponent. While Iwo Jima relied on the static nature of the Japanese defences to avoid the need for another human player, and B-17 created opposition by the use of simple charts and dice rolls, Ambush! had an innovative set of "mission cards" that one read in a view sleeve, with entries corresponding to the hexes on the game map.
Poker Squares (also known as, Poker Solitaire, or Poker Patience) is a patience game with the objective of building the best poker hands using just 25 cards from the deck. [1] It rewards both lucky guessing and accurate calculation of odds.
Straddling checkerboard. A straddling checkerboard is a device for converting an alphanumeric plaintext into digits whilst simultaneously achieving fractionation (a simple form of information diffusion) and data compression relative to other schemes using digits. It also is known as a monôme-binôme cipher.
