Phrases 19
- stream ciphera symmetric-key cipher in which plaintext digits are combined with a pseudorandom cipher digit stream
- Caesar cipherA 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.).
- Baconian cipherSynonym of Bacon's cipher: A certain method of steganographic message encoding.
- Bacon's cipherA certain method of steganographic message encoding.
- Vigenère cipherA text encryption technique that uses a series of different Caesar ciphers based on the letters of a keyword.
- Beaufort cipherA substitution cipher similar to the Vigenère cipher, with a slightly modified enciphering mechanism and tableau.
- block cipherAny deterministic cipher that operates on fixed-size groups of bits (binary digits), called blocks, with an unvarying transformation specified by a symmetric key.
- classical cipherA cryptographic algorithm was used historically and are easy to solve by hand or using modern technology.
- substitution cipherA 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 …
- transposition cipherAn encryption method that rearranges the order of the plaintext letters.
- rail fence cipherA transposition cipher in which the plain text is written in a zigzag fashion diagonally up and down on successive "rails" of an imaginary fence, and then the characters are read off in rows to obtain the ciphertext.
- Nihilist cipherA 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 …
- Playfair cipherA manual symmetric encryption technique that encrypts pairs of letters (digraphs).
- pigpen cipherA geometric simple substitution cipher, which exchanges letters for symbols which are fragments of a grid.
- Feistel cipherA symmetric structure used in the construction of block ciphers. It is an iterated cipher with an internal function called a round function.
- trifid cipherA classical cipher that extends the earlier bifid cipher with the use of trigrams.
- bifid cipherA classical cipher that combines the Polybius square with transposition, and uses fractionation to achieve diffusion.
- Gronsfeld cipherA variant of the Vigenère cipher that uses only ten different cipher alphabets, corresponding to the digits 0 to 9.
- Julius Caesar cipherSynonym 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.).
