Improved Security of the Data Communication in VANET Environment Using ASCII-ECC Algorithm

Now-a-days, with the augmenting accident statistics, the Vehicular Ad-hoc Networks (VANET) are turning out to be more popular, helping in prevention of accidents in addition to damage to the vehicles together with populace. In VANET, message can well be transmitted within a pre-stated region to attain system’s safety and also improve its efficacy. Ensuring authenticity of messages’ is a challenge in such dynamic environment. Though few researchers worked on this, security level is very less. Hence enhanced communication security on the VANET environment utilizing the American Standard Code for Information Interchange centred Elliptic Curve Cryptography (ASCII-ECC) is proposed in this paper. The network design is defined initially. Subsequently, the entire vehicles get registered to the Trusted Authority (TA); similarly, all vehicle users are registered with their On-Board Unit (OBU). This is followed by Median-centred K-Means (MKM) performs the cluster formation together with Cluster Head Selection (CHS). Next, TA takes care of the verification procedure. Modified Cockroach Swarm Optimization (MCSO) calculates the shortest path and the ASCII-ECC carries out the secure data communication if the vehicle is an authorized one. If not, TA sends the alert message for discarding the request. The system renders better performance when it was weighed against the top-notch methods.
