A Framework For Secured Dissemination of Messages in Internet of Vehicle (IoV) Using Blockchain Approach

Abstract

Growth of automated vehicle and emergence of Vehicular Social Network (VSN) gave rise to the various services such as traffic recommendation system, alert messages in case of danger and bad weather condition etc. All these communications are susceptible to various security and privacy attacks. Need of a robust infrastructure that is capable of guaranteeing communication with low storage cost for safety message and also thwart basic security attacks on the communicating vehicle. Vehicular Adhoc Network (VANET) provides a promising solution. PKI based infrastructure normally relies on a central trusted authority (TA) take decision and hence a collapse of TA leads the complete communication system down which may results in a catastrophe. Hence, a Blockchain based framework has been proposed to mitigate the security and privacy attacks. Theoretical analysis proves its effectiveness in storing a safety message as 2.33 MB per year.
