A Secured Dual Authentication Scheme for Data Transmission in VANET

Vehicular ad hoc networks (VANETs) are an important communication paradigm in modern-day mobile computing for exchanging live messages regarding traffic congestion, weather conditions. A trusted authority (TA) is designed to provide a variety of online premium services to customers through VANETs. TA classifies the users into primary, secondary, and unauthorized users. First, we present a dual authentication scheme to provide a high level of security in the vehicle side to effectively prevent the unauthorized vehicles entering into the VANET. Second, we propose a dual group key management scheme to efficiently distribute a group key to a group of users and to update such group keys during the users’ join and leave operations. From this project, we must send the messages or some safety information from the authority to the primary user and the primary user to the secondary user with full of secured process.
