Security & Privacy Preservation in VANET
Initiatives to create safer and more efficient driving conditions have recently begun to draw strong support. Vehicular Communications (VC) will play a central role in this effort, enabling a variety of applications for safety, traffic efficiency, driver assistance and infotainment. Security and privacy are indispensable in vehicular communications for successful acceptance and deployment of such a technology. Generally, attacks cause anomalies to the network functionality. A secure VANET system, while exchanging information should protect the system against unauthorized message injection, message alteration. In this paper, various security and privacy issues are discussed and try to solve it with effective cryptosystem.
