Secure Data Transmission Through Reliable Vehicles in VANET Using Optimal Lightweight Cryptography

Abstract

Vehicular Ad Hoc Networks (VANETs) is an important communication paradigm in modern mobile computing for transferring message for either condition, road conditions. A protected data can be transmitted through VANET, LEACH protocol based clustering and Light Weight cryptographically Model is considered. At first, grouping the vehicles into clusters and sorting out the network by clusters are a standout amongst the most comprehensive and most adequate ways. This in mechanism gives a solution to control the assaults over the VANET security. Improve the security dimension of data transmission through network framework the inspired Random Firefly (RFF) enhancement used to discover the reliable vehicles in created VNET topology. Once it’s identified the Lightweight Cryptography (LWC) with a Hash function which is used to secure the information in sender to receiver. The procedure utilized for encryption in which plain data is changed over into a cipher data alongside private and public keys. This security demonstrates it actualized in NS2 simulator with a simulation parameter, and furthermore, our proposed secure data transmission contrasted with existing security methods.
