Security is one of the existing challenge in cloud enabled Vehicular Ad-hoc Network (VANET) communication. To address the security issues and to reduce payload overhead a novel method has been proposed for classification of VANET messages along with a Multi-hashed Binary Tree (MuBT) Algorithm. This algorithm verifies the identity and authenticity of the vehicles and messages exchanged. In addition...
Authentication is an essential framework for safe and secure communication of messages in VANETs. For authenticating messages the IEEE 1609.2 standard uses ECDSA as the standard digital signature algorithm. But the verification time for an ECDSA signature is very high. As a result an inside or an outside attacker could use a fraction of bandwidth and flood the network with invalid signatures resulting...
