Abstract

An ignition start system in which authentication of a key is carried out twice, first to activate the ignition switch to allow starting the engine and second at the time when the brake is applied. The two step authentication prevents driving off in a car that has been started without having the key for security purposes and also to avoid inconvenient situations that can otherwise occur.
