Block4Forensic: An Integrated Lightweight Blockchain Framework for Forensics Applications of Connected Vehicles

Abstract

Today's vehicles are becoming cyber-physical systems that do not only communicate with other vehicles but also gather various information from hundreds of sensors within them. These developments help create smart and connected (e.g., self-driving) vehicles that will introduce significant information to drivers, manufactures, insurance companies and maintenance service providers for various applications. One such application that is becoming crucial with the introduction of self-driving cars is the forensic analysis for traffic accidents. The utilization of vehicle related data can be instrumental in post-accident scenarios to find out the faulty party, particularly for self-driving vehicles. With the opportunity of being able to access various information on the cars, we propose a permissioned blockchain framework among the various elements involved to manage the collected vehicle related data. Specifically, we first integrate Vehicular Public Key Management (VPKI) to the proposed blockchain to provide membership establishment and privacy. Next, we design a fragmented ledger that will store detailed data related to vehicle such as maintenance information/history, car diagnosis reports, etc. The proposed forensic framework enables trustless, traceable and privacy-aware post-accident analysis with minimal storage and processing overhead.

Blockchain‐based security aspects in heterogeneous Internet‐of‐Things networks: A survey

“…The Ethereum‐ControlChain ( E‐ControlChain ) was created as a ControlChain proof of concept to check ControlChain practical viability for the IoT. Their cost and performance analysis showed that even limited devices, like a Raspberry Pi, can easily handle the E‐ControlChain requirements. Cebe et al proposed Block4Forensic , which is a permissioned BC framework for managing the collected vehicle‐related data. Membership establishment and privacy is provided to the BC by a vehicular public key management (VPKI).…”

B-FICA: BlockChain based Framework for Auto-Insurance Claim and Adjudication

“…Consider a scenario where an auto manufacturer sends an update instruction to a CAV owner and the CAV owner fails to execute the update instruction and an accident occurs due to that faulty sensor. In alternative proposals such as [24], storing the hash of the update instruction in the BC serves as proof that the auto manufacturer sent the instruction. However, there is no proof to show that the target CAV received and executed the update instruction.…”
