Vehicular Ad-hoc network (VANET) has gained huge attraction from research community due to their significant nature of providing the autonomous vehicular communication. The efficient communication is considered as prime concern in these networks however, several techniques have been introduced to improve the overall communication of VANETs. Security and privacy are also considered as prime aspects of VANETs. Maintaining data security and privacy is highly dynamic VANETs is a challenging task. Several techniques have been introduced recently which are based on the cryptography and key exchange. However, these techniques provide solution to limited security threats. Hence, this work introduces a novel approach for key management and distribution in VANET to provide the security to the network and its components. This approach is later incorporated with cryptography mechanism to secure data packets. Hence, the proposed approach is named as Secure Group Key Management and Cryptography (SGKC). The experimental study shows significant improvements in the network performance. This SGKC approach will help the VANET user’s fraternity to perform secured data transmission.
