Upgrade Reliability for Novel Identity-Based Batch Verification Scheme in VANET

Abstract

A novel Identity-based Batch Verification Scheme in Vehicular ad hoc network (VANET) can outstandingly improve the traffic safety and effectiveness. The basic idea is to allow vehicles to send traffic message to roadside units (RSUs) or other vehicles. Vehicles have to be prohibited from some attacks on their privacy and misuse of their private data. For this reason, the security and privacy protection issues are important prerequisites for VANET. The Novel identity-based batch verification scheme was newly future to make VANET more secure and efficient for practical use. The current IBV system exist some security risks. To set up an improved scheme that can satisfy the security and isolation desired by vehicles. The proposed NIBV scheme provides the verifiable security in the casual Mysql model. In addition, the batch confirmation of the proposed scheme needs only effectual approach for VSNs to achieve confirmation, reliability, and authority. However, when the number of signatures received by a Roadside Unit(RSU) becomes bulky, a scalability problem appear immediately, where theRSU could be difficult to consecutively verify each received signature within 300 ms period according to the current committed short range communications broadcast protocol. To introduce a new identity- based batch verification scheme for transportation between vehicles and RSUs, in which an RSU can confirm abundant received signatures at the same instance such that the total verification time can be drastically reduced.
