A Framework for Data Security, Identification and Authentication in VANET

G.Archana ,S. Andal

The vehicular communication contains the safety and efficiency of transportation systems. Vehicular ad hoc networks (VANETs) enable vehicles to communicate with each other and road side units (RSUs). Service oriented vehicular networks are special types of VANETs that support infrastructure-based commercial services, including Internet access, real-time traffic management, video streaming, and content distribution. Privacy-preserving data acquisition and forwarding scheme by introducing a novel cryptographic algorithm for key generation and powerful encryption. Multiple numbers of users can connect for the communication. MREACT focuses on making the proposed system more scalable in terms of the number of users that can connect to an RSU. M-REACT provides the security for data and scheduling mechanism of RSU divided into number of time slots. In M-REACT that propose an algorithm that uses the key derivation function in several iterations to strengthen the security of the encrypted message.We provide a suite of novel security and privacy mechanisms in our proposed system and evaluate its performance using the ns2 software. We show, by comparing its results to those of another system, its feasibility and efficiency.
