Multidimensional Security Provision for Secure Communication in Vehicular Ad Hoc Networks Using Hierarchical Structure and End-to-End Authentication

Vehicular ad hoc networks (VANETs) have been considered as one of the most influential applications of mobile ad hoc networks. The VANETs have also become an important part of Internet of Things. Along with the advantages, such networks are facing a number of security issues. A number of research have been done so far to identify the solution of the security problems in the VANETs. But the existing solutions do not confirm the confidentiality-integrity-availability (CIA) triad services simultaneously. Therefore, in this paper, we have provided a solution for the VANETs security using end-to-end authentication to avoid intrusion in the VANETs. After verifying the communicating entities, the data are transmitted in encrypted form thus the proposed approach provides CIA security services to VANETs communication. Along with this, we have used a sandboxing method for in-vehicle communication for prevention of intrusion in form of downloaded information. Moreover, in this paper, the VANETs are considered as a hierarchical model to concentrate on a less number of message exchanges. Furthermore, the simulation results show the efficiency of our proposed solution.
