DAKAA: Double Authentication and Key Agreement Algorithm for securing Vehicular Ad hoc Networks

Vehicular ad hoc network plays a vital role in communication paradigm that aims to provide innovative services. Vehicle-to-Vehicle communication is a realistic wireless transmission between the vehicles, which needs security services for safety communication. Priority-based authentication and fuzzy-based techniques are used to ensure the authentication process in existing works. Even though, some attack can break the authentication process such as brute force attack and private keys can also be hacked. Hence, the proposed scheme uses double authentication and key agreement algorithm (DAKAA) to prevent the unauthorized users or vehicles entering into the system to provide largest and competent private key using RSA cryptosystem in order to avert brute force attacks. The performance of DAKAA was compared with the existing schemes concerning verification delay, transmission overhead and service response time. DAKAA achieves better results due to prior detection of malicious vehicles for effective safety communication.
