Abstract |
VANET is a subcategory of MANET with unique features of Vehicle-to-Vehicle communication, Vehicle-to-RSU communication and Vehicle-to-Trusted Authority communication. VANET has a dynamic topology. Now-a-days VANET has been ultimately a hot research topic for the researchers and work is in progress for the improvement in this area. However, there is gap found needs to be filled, as in the existing scheme, authors used HECC for both encryption/decryption of data and also for secure key exchange. The existing scheme is more complex due to which, timely data availability is a problem and face problems of node authenticity, non-repudiation and similarly the problem of cost i.e. storage cost, communication cost and also computational cost. In our propose scheme we use a hybrid approach, which contain blowfish algorithm (called symmetric algorithm) and HECC (called asymmetric algorithm). Blowfish algorithm is used for confidentiality i.e. encryption/decryption of data and HECC is used for secure key exchange. The objective of our propose scheme is to securely transmit data among vehicles, RSU and server, and protect various security attacks on VANETs, while keeping in view the efficiency in terms of cost as well as the privacy of messages transmission. |
