An Efficient Secure VANET Communication Using Multi Authenticate Homomorphic Signature Algorithm

Abstract

Vehicular Ad-hoc Networks (VANETs) is a wireless network that provides communication between vehicles and roadside infrastructure. It has been gaining high attention in the field mainly by researchers recently. It can provide various services, ranging from security-related early warning systems, enhanced navigation mechanisms, and information and entertainment applications. In VANET systems, some confidential data and contact information leakage can cause a severe loss of property. After that, it is a need for a higher level of security VANET system. Therefore, in VANET is the urgent priority need for security of privacy protection protocol. The proposed method Elliptic Homomorphic Signature (EHS) the critical requirement is to allow VANETs privacy protection protocol to ensure its authenticity for the use of trademarks. When the user signs data, the signature is generated using the secret key, which is kept secure by the signer, and it encrypts the data. No one can create any signature items other than legitimate users. Destination to receive data using the public key confirms has not been modified in transit. The attacker can neither find the correct signature nor steal the data. The simulation results, when used in VANET, confirmed the level of effectiveness and security.
