A Warning Message Dissemination Scheme with User Privacy and Message Integrity for VANET
Keywords:Warning Message Scheme, Alert Notification, User Privacy, Message Integrity, Broadcast Scheme
Vehicular ad hoc networks (VANETs) are wireless networks which are infrastructure-less in nature because of the highly mobile nodes (vehicles) in the network. Warning message dissemination can be considered as the primary application of VANET, where in alert messages need to be quickly as well as smartly disseminated in the network to make it available for a large number of vehicles. A scheme will be effective once it reaches to maximum number of
vehicles with minimum overhead and delay, for attaining the same a broadcast scheme is familiarized in this paper along with user privacy and message integrity. User privacy is an added advantage for all the participating vehicles which makes the system more acceptable as a whole. Protecting the privacy of users leads to undesirable tracking of vehicles by attackers. A part from user privacy, message integrity is also been guaranteed in the proposed scheme. Integrity of the message can be checked in order to confirm whether the received alert is genuine. This paper presents a warning message dissemination scheme along with the mechanisms to ensure user privacy and message integrity.
