A Survey on Dual Authentication and Key Management Techniques for Secure Data Transmission in Vehicular Ad Hoc Network

Abstract

VANET is a self-organizing communication network that is created among the moving vehicles. VANET have recently become popular for research, with attention to advance the driving experience and road protection. VANET usually incorporate Trusted Authority (TA) that is meant to source online premium service to nodes in network. It is required to keep up the authentication and confidentiality of the messages transmitted between the TA and nodes. Hence the address security issues and challenges where TA classifies the VANET nodes into primary, secondary and unauthorized users. So therefore, in this project have proposed a dual authentication scheme to produce advanced security level to effectively that stops the unauthorized vehicle entering into VANET environment using smart card. Second, we tend to propose a Batch Level Signature (BLS) group key management theme with efficiency distributing a group key to different VANET nodes. From this project, must send the messages or some safety information from the Trusted authority to the primary user and then primary user to the secondary user with full of secured process..
