Found via reverse dictionary — words that share a conceptual meaning.
| Word | Definition |
|---|---|
| transposition ciphernoun | (cryptography) An encryption method that rearranges the order of the plaintext letters. |
| affine cipher | The affine cipher is a type of monoalphabetic substitution cipher, where each letter in an alphabet is mapped to its numeric equivalent, encrypted using a simple mathematical function, and converted back to a letter. |
| hill cipher | In classical cryptography, the Hill cipher is a polygraphic substitution cipher based on linear algebra. |
| permutation boxnoun | (cryptography) A method of permuting or transposing bits (binary digits) across S-box inputs while retaining diffusion. |
| 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. |
| hybrid cryptosystem | In cryptography, a hybrid cryptosystem is one which combines the convenience of a public-key cryptosystem with the efficiency of a symmetric-key cryptosystem. |
| 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. |
| homomorphic secret sharing | In cryptography, homomorphic secret sharing is a type of secret sharing algorithm in which the secret is encrypted via homomorphic encryption. |
| substitution ciphernoun | (cryptography) A method of encryption by which units of plaintext are substituted with ciphertext according to a regular system; 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 performing an inverse substitution. |
| caesar ciphernoun | (cryptography) A simple form of encryption in which each letter in the plaintext is shifted through the alphabet a number of positions (for example A→D, B→E, C→F, etc.). |
| rabin cryptosystem | a family of public-key encryption schemes |
| linear cryptanalysis | In cryptography, linear cryptanalysis is a general form of cryptanalysis based on finding affine approximations to the action of a cipher. |
| elliptic-curve cryptographynoun | (cryptography) A branch of public-key cryptography in which elliptic curves are used to generate key pairs. |
| elgamal encryption | In cryptography, the ElGamal encryption system is an asymmetric key encryption algorithm for public-key cryptography which is based on the Diffie–Hellman key exchange. |
| ciphernoun | A method of transforming a text in order to conceal its meaning. |
| block ciphernoun | (cryptography) Any deterministic cipher that operates on fixed-size groups of bits (binary digits), called blocks, with an unvarying transformation specified by a symmetric key. |
| differential cryptanalysis | a general form of cryptanalysis applicable primarily to block ciphers, but also to stream ciphers and cryptographic hash functions. |
| euler's factorization method | a technique for factoring a number by writing it as a sum of two squares in two different ways. |
| tabula recta | In cryptography, the tabula recta (from Latin tabula rēcta) is a square table of alphabets, each row of which is made by shifting the previous one to the left. |
| bifrustumnoun | A polyhedron constructed from two congruent frusta combined across a plane of symmetry, or equivalently from a bipyramid with the two polar vertices truncated. |
