A Novel Secure Authentication Scheme for VANETs

In wireless networks, Vehicular Adhoc Network (VANET), is one of most recent research area, which is growing day by day. It is used to provide an efficient Traffic Information System (TIS), Intelligent Transportation System (ITS), and Life Safety. Authentication is an emerging issue for VANET security. There are many authentication schemes which have been proposed for stabilized communication among autonomous entities for efficient, fast, scalable and reliable data transmission. In current scenario, there is not adopted a real-life general solution in the worldwide standard for the autonomous mobile node authentication in VANETs. Here introducing a new efficient secure scheme that is "A Secure Authentication Scheme for VANETs", combination of Group signature and Identity based(ID-based) Signature scheme. The scheme Provides cost effective, highly privacy preserving of user, efficient message authentication and verification than existing system for VANETs. Only Authentic mobile node can enter in secure VANETs system. Group leader Local Authority (LA) can authenticate messages without involvement of concern Central Authority (CA). Malicious mobile node can very easily identify at beginning of joining the system and the system are trusty for all new mobile node to join VANETs. The scheme more suitable for high traffic density area or urban area, performance is more better in highly density traffic area and easy to verification of messages. The new anonymous authentication schemes which are more secure efficient, robust, and scalable for VANET's authentication and provide real-life solution match with the standard.
