Efficient Certificate Management in Blockchain based Internet of Vehicles

Abstract

Driving to the research trend to the Internet of Vehicle (IoV), the issues of privacy and security of each internet car become popular. We focus on the certificate management to reduce the cost of certificate validation securely. In this paper, we use the blockchain technology to address the distribution and management of the Certificate Revocation List (CRL) in vehicle public key infrastructure (PKI). Our proposed scheme uses the activation codes to validate the certificate depends on time to non-revoked vehicle for blockchain mechanism. We intend to reduce the verification cost and naturally remove the certificate of inactive cars.
