Mrs. Bhuvaneswari. M. S. "Secure Data Transmission in VANETs" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-2 | Issue-3, April 2018, pp.1966-1970, URL: https://www.ijtsrd.com/papers/ijtsrd11561.pdf

A number of technical problems are arising with the widespread distribution of vehicular ad-hoc networks. Privacy and authentication mechanisms are of major concern. If security is not integrated with the system, it leads to anti-social and criminal behavior and endanger the benefits of the deployment of VANETs. A suitable authentication procedure is to implement the Public-Key Infrastructure (PKI) , where each node in the VANET has a set of authentic certificates. Traditional PKI systems makes use of Certificate Revocation Lists to check the validity of the certificate and thereby the signature. In this paper, a new method that replaces CRL with revocation checking process is proposed. When a node is found to be illegitimate or compromised, it is revoked by generating a revocation message and broadcasting to all other nodes in the network. The time consuming CRL checking need not be done for each message received. The method proves to be faster in authenticating messages securely. This is suitable not only for VANETs, but for any other network that deploys PKI.
