A study on M/sup n/ coding for guarding against theft and remote control device of an automobile

Abstract

This paper mainly discusses a method of M/sup n/ coding and design of its hardware by using a multi-mode logic unit, and put forward a new solution method in which M/sup n/ coding is used to guard against theft and in remote control devices. The cost of this hardware is cheap, the coding number is massive, the coding method is simple and its decoding is difficult. Therefore, the method is suited to large-scale production in a factory.
