Abstract

Communication security is a significant problem to be resolved in vehicular ad hoc network (VANET) to enhance the traffic safety and efficiency. Few research works have been designed in existing works to authenticate vehicular nodes in VANET before data communication.  But, the authentication efficiency of conventional techniques was poor. In order to overcome such limitations, Probabilistic McEliece Public-Key Cryptography based Identity Authentication (PMPC-IA) Scheme is proposed. The CPPKC-IA technique includes three phases namely registration and key generation, encryption and decryption for improving security level with a lesser time consumption and higher data integrity rate. In registration and key generation phase of CPPKC-IA technique, the vehicular nodes (VN) and Roadside Unit (RU) register their information to Trusted Authority (TA). After completing registration, TA generates identity and a key pair (i.e. public key and secret key) for every registered VN and RU in VANET, Then, sender VN

encrypts the data with their public key and sends encrypted traffic information to the RU or VN.  At the receiver side, TA checks the authenticity through checking identity. When the identity gets matched, then that VN or RU is said to be authenticated and decryption is allowed. In data decryption phases, the data gets decrypted with secret key of receiver. This helps to enhance the security level during VANET communication with a lower time. The simulation process of CPPKC-IA technique is carried out on factors such as authentication efficiency, data integrity rate and communication overhead with respect to a number of vehicular nodes. The simulation result demonstrates that the CPPKC-IA technique is able to increase the authentication efficiency and also minimizes the communication overhead in VANET as compared to state-of-the-art works.
