Securing Vehicular Ad Hoc Data Transmission by Dual Authentication and Group Key Management Techniques

Computer Science and Engineering

VANET is a self-organizing communication network that is constructed among the moving vehicles. VANET have recently become popular for research, with attention to improve the driving experience and road safety. VANET usually encompass Trusted Authority (TA) that is meant to supply online premium service to nodes in network. It is necessary to keep up the authentication and confidentiality of the messages transmitted between the TA and nodes. Hence we address the security issues and challenges where TA classifies the VANET nodes into primary, secondary and unauthorized users. We propose dual authentication scheme to produce advanced security level to effectively stop the unauthorized vehicle going in VANET environment using smart card. Second, we tend to propose a group key management theme with efficiency distribute a group key to different VANET nodes. From this project, we must send the messages or some safety information from the Trusted authority to the primary user and the primary user to the secondary user with full of secured process.
