An efficient blockchain assisted dynamic authentication scheme for geo-spatial enabled vehicular network

The primary goal of vehicular networks is to increase vehicle safety as well as transportation efficiency with the application of wireless communications technology. Therefore, it is crucial to develop an effective data distribution mechanism that notifies vehicles of significant safety incidents. Two recent developments that could assist a vehicular network in this regard include geospatial and blockchain technology. With the help of distributed nodes and geo-locations made possible by blockchain technology, it is possible to investigate the patterns of participants both spatially and geographically. The primary objective of this work is to create, implement, and evaluate an effective dynamic authentication scheme for a geospatially enabled vehicular network using blockchain technology. The proposed scheme’s security and correctness are demonstrated using the random oracle model and the study of performance shows that it meets the requirement of less communication and computation overhead. It is also proven secure against active as well as a passive adversary. However, precise informal security analysis and verification have been done using widely adopted “Automated Validation of Internet Security Protocol and Application”(AVISPA) tool. The proposed scheme’s suitability for a vehicular system is demonstrated by its performance and security analysis.
