ABSTRACT
One of the main problems in the field of transportation is the diversity of the concepts
of vehicle security that has been lately elaborated under continuous threat of
technology spreading in a very chaotic manner, issue that opposes many obstacles
when evaluating the security measure of such technique on the ground, especially
when dealing with very important person (VIP) security, and its constrains. This
paper aims to develop a scientific approach to integrate three levels of car security
namely life saving, car theft prevention and user access security with respect to
current technologies. Novel double identification code applications are introduced.
The introduced applications use the traditional radio frequency car key considering
Actual threats and limited budget using novel methodologies. They enhance the
fixed code key security to achieve the security level of rolling code key. Experimental
work has been carried out using the two standard car communication frequencies
namely 315MHz and 433.9MHz simultaneously to transmit two different fixed car
codes with a spatial frequency separation.
