Security Provision In VANETs Using Group Based Key Share Algorithm

In today's world VANET get a lot of attention because of its easy and comfortable less infra-structure and life-saving factor. But whatever the facilities is available now it's not properly able to provide a strong security to the vehicle to vehicle (V2V) or vehicle to infrastructure communication (V2I) so attacks obey the authentication, confidentiality, and security which can influence the privacy of the user. The mechanism of VANET is unloosed with a lot of security risk nowadays. This paper gives an idea of VANETS architecture, existing work in VANET with security issues and challenges. Further, provide the solution to that issue with comparative analysis and use group-based key share algorithm which is enhanced the privacy of users and provides some research guidance for upcoming work.
