Secure Vehicular Ad Hoc Network Communication using BlockChain

Abstract

The vehicular social networks supports diverse kinds of services such as traffic management, road safety, and sharing data. Among these, secure data transmission has turned to be a spotlight. Ciphertext- policy attribute- based encryption may be adopted for data sharing. In traditional schemes, access policy is stored and granted by the cloud, which lacks credibility. To end this, we present a Blockchain Based Multi-Domain Vehicular Authentication scheme, in a which privacy-preserving authentication method is proposed to guarantee the Security.
