Manipulation of electronic devices and data in dispensing pumps

Abstract

The sale of fuel through electronics controlled based Dispensing units in the retail outlets are the source of manipulation. The stake holders are customers and are directly affected by the unauthorized manipulation by the petroleum product selling units. The electronic devices are more prone for changing the original encrypted data or stored data as a program. The program stored in this device can be altered unauthenticated by external device attached to the original circuit’s boarders. The circuits board is build with the microcontroller based hardware that controls the outlet pipe by setting the control signal by the selling unit. This can be alter by changing the pulse which are used to modulate the information bits so that cheating the customer by alter the set control bit by deliver less or more through the dispensing unit. This research article focus on explore the possibilities to make the encryption method of control bits more robust than the present simple pulse modulation techniques.
