A Novel Mechanism for Secure and Efficient VANET Communication
نویسندگان
چکیده
A Vehicular Ad hoc NETwork (VANET) is a type of mobile Peer-To-Peer wireless network that allows providing communication among nearby vehicles and between vehicles and nearby fixed roadside equipment. The lack of centralized infrastructure, high node mobility and increasing number of vehicles in VANETs result in several problems discussed in this paper, such as interrupting connections, difficult routing, security of communications and scalability. Existing system for VANET communication is proved to have several drawbacks. We have proposed a mechanism in order to provide secure and efficient communication in VANET environment. We overcome the drawbacks of the existing system by using Malicious Vehicular Analyzer algorithm and Elliptic Curve Cryptography (ECC). Using these algorithms, malicious messages are identified. It also detects the accident and other problems in the path of the vehicles. Elliptic Curve Cryptography (ECC) algorithm is used for stronger security during communication.

متن کاملAn Efficient and Practical Authenticated Communication Scheme for Vehicular Ad Hoc Networks
In the vehicular ad hoc networks (VANET), various authentication schemes have been proposed for secure communications. However, the previous schemes are inefficient because each vehicle needs to share and keep a large number of session keys for communicating with the other vehicles on the VANET. To overcome the above drawback, we propose a new authenticated communication scheme for the VANET. I...
