Cloud computing is a network access concept that provides simple, on-demand network access to a shared pool of customizable computing resources (such as networks, servers, storage, applications, and services) that can be quickly provided and released with minimal administrative effort or service provider involvement. The idea of having a communication node on-board a vehicle that may make wireless connections with other adjacent communication nodes visible in the radio range is referred to as a Vehicular Adhoc Network (VANET). The main focus of this paper is to design lightweight Vehicular Adhoc Network architecture for efficient secure data transmission. An improved Ciphertext Policy Attribute Based Encryption scheme and Identity Based offline/online Signature scheme are proposed to reduce the computational cost, storage overhead and communication overhead in vehicular ad-hoc network. Finally, concluded that the proposed work yields high performance than the existing work.
