An Enhanced Secure PKI Authentication Scheme For Vehicular AD-HOC Networks

Abstract

For the past few years, Vehicular Ad Hoc Networks (VANETs) have been attracting researchers across the globe due to their usage in wide areas of networks. VANETs bring a revolutionary change to the current on road experience of drivers. This network deals with communication of nodes which are dynamic nature. Due to this reason, issues exist in both efficiency and security of this system. Security is one of the most important components which needs to be investigated further in VANETs as bogus information may mislead the users. In past, numerous schemes have been proposed to prevent different kinds of attacks for increasing the efficiency of various applications in VANETs. In this dissertation, a new scheme is proposed which identifies the pitfalls in the existing Wang et al. [20] scheme. The proposed scheme is evaluated in comparison to the existing scheme by using various evaluation metrics and attacks in VANETs, where its performance was found better than the above said scheme. Various types of attacks are identified and their performance in comparison to the proposed scheme is evaluated.
