Abstract

Preservation of security is an essential requirement in vehicular ad hoc networks (VANETs) as vehicular communication is vulnerable to attacks. Attackers may exploit VANETs to send bogus information to deceive other vehicles which leads to serious issues. In this paper, we describe an advanced Secure scheme based on Clustering and Key Distribution (SCKD) among members and cluster-heads in VANET. The SCKD is a coordination based algorithm in which nodes are located within different clusters and their cluster heads are chosen from trusty nodes. For a secure end-to-end communication, our scheme deploys the proxy signature, blind proxy signature, hashed message authentication code, and symmetric cryptography. Results show that our scheme preserves security requirements including authentication, confidentiality, data-integrity, non-repudiation, and unforgeability. Since the cost and time computation of key generation and distribution decreases by SCKD compared with other algorithms, our algorithm will be applicable for VANETs.
