Enhanced Security for Information Flow in VANET Using Signcryption and Trust Level
Security in vehicular ad hoc network has always been a major research area. Reducing cost of computation, effective consumption of limited resources and providing uncompromised security has always been a challenge over VANET. Two levels of security have been proposed based on signcryption and node trust. Using signcryption the computation cost is reduced as compared to sign-then-encryption and also the confidentially and integrity of the message is conserved. By assigning trust levels to every node the malicious nodes or misbehaving nodes are removed from the network. Providing confidentiality, Integrity of the message, detecting and removing malicious and misbehaving nodes from VANET are the main focus of this paper.
