Sažetak
Vehicular Ad-hoc networks (VANETs) during the communication process, nodes are always varying and the process is always under security threats like Sybil attacks, masquerading attacks, etc. In order to reduce the probability of these attacks and to regulate traffic flow in the network, a software-defined network (SDN) is used. The SDN is used for implementing protocols like OpenFlow and reducing the routing load in the network, but it doesn’t provide a high level of security to the network, hence protocols like encryption, hashing, etc. are applied to the VANET. In the paper, SDN based blockchain-inspired algorithm is implemented, which coordinates network traffic and improves the overall security of the network. Security analysis of the proposed algorithm shows that the combination of blockchain with encrypted SDN is removing more than 95% of the network attacks as compared to its non-blockchain counterparts.
