Phrases 14
- block ciphersplural of block cipher: Any deterministic cipher that operates on fixed-size groups of bits (binary digits), called blocks, with an unvarying transformation specified by a symmetric key.
- stream ciphersplural of stream cipher: a symmetric-key cipher in which plaintext digits are combined with a pseudorandom cipher digit stream
- substitution ciphersplural of substitution cipher: 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 …
- Vigenère ciphersplural of Vigenère cipher: A text encryption technique that uses a series of different Caesar ciphers based on the letters of a keyword.
- Beaufort ciphersplural of Beaufort cipher: A substitution cipher similar to the Vigenère cipher, with a slightly modified enciphering mechanism and tableau.
- Caesar ciphersplural of Caesar cipher: 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.).
- classical ciphersplural of classical cipher: A cryptographic algorithm was used historically and are easy to solve by hand or using modern technology.
- Nihilist ciphersplural of Nihilist cipher: 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 …
