| Word | Definition |
|---|---|
| bifid ciphernoun | (cryptography) A classical cipher that combines the Polybius square with transposition, and uses fractionation to achieve diffusion. |
| feistel ciphernoun | (cryptography) A symmetric structure used in the construction of block ciphers. It is an iterated cipher with an internal function called a round function. |
| nihilist ciphernoun | (cryptography, historical) A symmetric cipher in which a Polybius square using a mixed alphabet is used to convert both the plain text and a keyword to a series of two-digit numbers, which are then summed in the normal way to get the ciphertext, with the key numbers repeated as required; (by extension) any of several improved algorithms based on this. |
| asymmetric cryptographynoun | cryptography in which the key used in decryption is different from that used for encryption. |
| fractionationnoun | (chemistry, uncountable, countable) A separation process in which a certain quantity of a mixture is divided up into smaller quantities (fractions) in which the composition changes according to a gradient; an instance of this process. |
| cryptofunctionnoun | (cryptography) A mathematical function used to carry out cryptography. |
| cryptosystemnoun | A system of cryptography. |
| cryptovariablenoun | (cryptography) The key used for encryption and decryption. |
| split keynoun | (computing) A key value used to identify where to split the children of a parent node in a B-tree or similar data structure. |
| s-boxnoun | (cryptography) A basic component of symmetric-key algorithms, which performs substitution, transforming one set of bits into another. |
| block designnoun | (mathematics) In combinatorial mathematics, a set together with a family of subsets (repeated subsets are allowed at times) whose members are chosen to satisfy some set of properties deemed useful for a particular application. |
| permutation boxnoun | (cryptography) A method of permuting or transposing bits (binary digits) across S-box inputs while retaining diffusion. |
| depthnoun | the vertical distance below a surface; the degree to which something is deep |
| bit slicenoun | (mathematics, computing) Any of a group of variable-length words that may be combined to form computable lengths of bits of any length |
| block modelnoun | (shipbuilding) A scale model of a ship to be built, showing the vessel's water line. |
| feistel networknoun | Synonym of Feistel cipher. |
| subkeynoun | (computing, Microsoft Windows) A key located beneath another key in the registry. |
| block cellular automatonnoun | (cellular automata) A cellular automaton in which the grid is divided into distinct blocks in a uniform pattern, with the blocks being shifted by a certain number of cells in each generation, and each block serving as the neighborhood for all cells contained within it. |
| cryptarithmnoun | Synonym of alphametic (“type of puzzle”). |
| polybius squarenoun | (cryptography) A grid used for fractionating plaintext characters so that they can be represented by a smaller set of symbols. |
