Improving security and privacy in VANET network using node authentication

Abstract

The security of vehicular ad hoc networks is a serious problem (VANETs). Group- based communication on VANETs is a well-studied issue. Creating a group and distributing a key to a large number of fast-moving vehicles for secure communication is a significant security problem for VANETs. Distributed keys in VANETs enable the secure participation of vehicles that were not present when the group was created. Using polynomial interpolation, this study provides a new distributed key technique for safe group administration in VANET. This allows attackers to either steal the identity of the legal intermediary node or directly join the identified data transfer path. As a result, VANETs are particularly vulnerable to assaults. Also, the number of VANET applications has increased significantly in recent years due to advances in handheld device technology and wireless network deployment technologies. The flooding assault might target the targeted node or the network as a whole. This exploit targets network resources such when two hostile nodes (attackers) spread incorrect network information to their neighbors during routing table building, they become intermediate nodes on the designated route and discard data packets during communication. The proposed approach not only offers a distributed key for vehicles to form, join, and interact in the group, but it also provides and controls key distribution to ensure the security of VANETs. The experimental findings show that the suggested system is a safe option for group communication in VANETs.
