A Secure Data Transmission in VANETs using HC12

Vehicular ad hoc networks (VANETs) is an Intelligent Transportation System and a part of MANETS. VANETs communication is wireless between vehicles and different nodes along the road to increase efficiency and human safety. VANETs embedded all the features of MANETs and almost any Ad Hoc Network. We have discussed various features of VANET and different types of attacks, since the VANET communication is open in nature; they are prone to various types of attacks. Although various attractive features, VANETs also face some challenges like communication with different types of nodes and sensors and gather information or data. Our major focus is on securing this data or information sent by the sender node before transmitting on the network to another node in the network. We intend to solve this by using a wireless LoRa module and cryptography algorithm like ECDH for secure data transmission and solve the security risks and privacy problems. Our work discusses VANET communication method and structure. We provide a simple communication method using P2P topology method and ECDH cryptographic algorithm for keeping the data secure.
