Abstract
Automatic toll collection systems have been known to operate with a backscatter mechanism. Such systems are highly prone to eavesdropping despite the security measures implemented, as the data can be stored and processed later for the transaction. In this paper, we analyse the probability that secrecy is compromised in the automatic toll collection systems using the physical layer security principles. We perform simulations to corroborate the analytical results in the proposed fading channel environment. The results are obtained for different distances between the tag and the reader and that between the tag and the eavesdropper. The analytical and simulation results are found to be in close agreement.
