Abstract
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 to this, the concept of public cloud is used to store the location of vehicles, keys, messages and certificates involved in VANET communication. This ensures any time data accessibility from anywhere and helps to track the messages when necessary. The messages exchanged and the Transient Certificates (TCs) used in VANET communication is encrypted using the geolocation key of the RSU. The use of geolocation key provides location confidentiality against vehicles outside the zone and also ensures that a message can be sent only if the vehicle is physically present in the location.
