Abstract
A system and method to access a machine through a mobile device includes sending a machine key to a controller on-board the machine, and a mobile device key to the mobile device using a remote server. The mobile device sends a mobile device ID to the controller. The controller determines the mobile device key based on the mobile device ID and the machine key. The controller sends a random number to the mobile device. The mobile device processes the random number to derive a first processed random number, and sends the first processed random number to the controller. The controller processes the random number to derive a second processed random number. The controller enables a start button to send a request to start the machine, when the first processed random number matches the second processed random number. The controller starts the machine upon receiving the request to start the machine.
