Improving Vehicular Authentication in VANET Using

Abstract

In the last several years, many types of research are focusing on Vehicular Ad-hoc Networks (VANETs) field due to the lifesaving factor. VANETs are defined as a set of vehicles in the road interact with other vehicles or with the Road Side Unit (RSU) through wireless Local Area Network (WLAN) technologies. The fundamental advantages of VANETs are enhancing the road and driver's safety and improving the vehicle security against adversaries’ attacks. Security is the most difficult issue belonging to VANETs since messages are exchanged through open wireless environments. Especially in the authentication process, the vehicles need to be authenticated before accessing or sending messages through the network. Any violation of the authentication process will open the whole network for the attack. In this paper, we applied security algorithms to improve authentication in VANETs with four stages of cryptography techniques: challenge-response authentication, digital signature, timestamping, and encryption/decryption respectively. Also, we also proposed an algorithm model and framework. Finally, we implemented the challenge-response authentication technique, and then measured and evaluated the result from the implementation
