Hash Authentication VANETS Message (HAVM) Against Message Tampered (MITM Attack)

Abstract:

Vehicle Ad-Hoc Networks (VANET) promises to enhance traffic management and road safety. However, data can be at stake by an attacker due to the dynamic network topology. The attack Man in the Middle (MITM) is probably a remarkable one in security attacks, especially tampered message attacks. This attack modifies essential information, misleading the communicated nodes, and possibly creating disasters. To address this problem, we propose a novel method for trust message validation between vehicles through the implementation of a hash algorithm, namely hash authentication VANET message (HAVM). Every node has the capacity to detect if a message has been tampered. HAVM vehicles generate a unique code per message. When this message is distributed among the VANET, the HAVM vehicles will be able to analyze whether this code belongs or not to the received message. Several simulations were carried out to evaluate the performance of HAVM. The simulation showed that a network with 70% of vehicles with HAVM, and 10% of MITM vehicles, improved the state of the Content Delivery Radio (CDR) by 14% in reliability than in a network without HAVM nodes.
