Abstract

VANET is subpart of MANET and the significance and popularity of VANET are increasing now a day because of their great contribution to improving traffic efficiency and safety. However, communication between two or more vehicles or with RSUs needs to be secured as well as authenticated. We have focused on to reduce the authentication time, that’s why we used the proxy vehicle which is verified by both RSU and CA; proxy vehicle will do half of the authentication process and reduce the authentication time. The simulation results show that proposed approach minimizes the authentication time, delay, packet loss due to the collision of the packet in the network and also increase the overall throughput of the network. In this paper, we also discussed the Elliptic Curve Cryptography algorithm (ECC) approach which uses the vehicle ID, a randomly generated prime number and time stamp to encrypt the message in a secure manner. As a result the whole VANET network will be secured and faster in handling the congestion during peak hours.

Abstract

The significance and popularity of VANET is increasing nowadays because of their great contribution in improving traffic efficiency and safety. We present an authentication and verification scheme of the Vehicular Ad-hoc Networks VANET for the low as well as high traffic conditions. However, communication between two or more vehicles or with RSUs needs to be secure as well as authenticated. In this paper we will discuss the Elliptic Curve Cryptography Algorithm (ECC) approach which uses the vehicle ID, a random generated prime number and time stamp to encrypt the message in a secure manner. Our main focus is to reduce the authentication time; therefore we have used the proxy vehicle which is verified by both RSU and CA and they will do half of the authentication process and decrease the authentication time. In this paper we have taken the parameters of packet loss, delay and throughput and compared the proposed approach for the low traffic conditions and also for high traffic conditions. So the result shows that the proposed scheme provides high quality of message authentications in less time period on both the traffic conditions without affecting the overall security of VANET.
