In the emerging world the Vehicular Ad-hoc Network (VANET) plays a vital role in the Intelligent Transportation Sector (ITS). Basically VANET are exposed rapid topology changes, dynamic network environment, intermittent connectivity and fluctuating communication range which leads to security and privacy concerns. To address these issues, in this work, an enhanced pairing free certificate less aggregate authentication scheme is proposed. The proposed method employs Elliptic Curve Cryptography (ECC) instead of bilinear pairing algorithm to reduce the overhead and to provide efficient security in the network. Further, during the communication and authentication phases the message transmission takes place in an aggregate manner which in turn reduces the time and storage in the network. The novelty of the proposed work is that the use of aggregation scheme which reduces the delay during the …
