Code System
  • Any system of communication in which groups of symbols are used to represent plain text elements of varying length.
  • in the broadest sense, a means of converting information into a form suitable for communications or encryption, for example, coded speech, Morse Code, teletypewriter codes.
  • A cryptographic system in which cryptographic equivalents (usually called code groups) typically consisting of letters, digits, or both in meaningless combinations are substituted for plain text elements which may be words, phrases, or sentences. (FIPS PUB 39) See BREVITY LISTS.
