[PAR] [TLE] Vigenère cipher [SEP] The Vigenère cipher is a method of encrypting alphabetic text by using a series of interwoven Caesar ciphers based on the letters of a keyword.  It is a form of polyalphabetic substitution. [PAR] [TLE] Polyalphabetic cipher [SEP] A polyalphabetic cipher is any cipher based on substitution, using multiple substitution alphabets.  The Vigenère cipher is probably the best-known example of a polyalphabetic cipher, though it is a simplified special case.  The Enigma machine is more complex but still fundamentally a polyalphabetic substitution cipher.
