ABSTRACT:
Three variations of a method of representing (abstract) state machines as polynomial mappings, and three variations of a corresponding encryption program stored on a computer readable medium. The encryption program is based directly on symbolic functional composition of polynomial mappings with permutations expressed as polynomial mappings.
