Paper Title
A Novel Methodology to Achieve Effective Message Authentication in VANET
Abstract
The proposed scheme offer cooperation amongst the vehicle users in vehicular Adhoc network which offers them
to communicate with each other safely, and achieves cooperative message authentication in the network. In this process the
vehicle users can send and receives messages which are paired with some signature like some private keys which can help to
maintain the message privacy between vehicle users. The process includes generation of tokens by trusted authority to
vehicle users which is valid for limited time period. In proposed scheme numbers of RSUs are installed to keep track of the
communication process and also the malicious activities which are undesirable to the process. As per increase in number of
users, and traffic, it is necessary to pay attention on the security issues of the VANET. Especially in authentication process
of VANET there are more chances of the attacks by malicious users. It is necessary to secure the vehicular Adhoc networks
while authentication process is going on. In this paper we have proposed the schemes to stop such malicious behavior of fake
vehicle users.
