Abstract: In this paper, we present a tiered vehicular forensics framework based on permission BlockChain. We integrate all entities involved in the forensics process and record their interactions in the BlockChain to generate comprehensive evidence for settling disputes and appropriating blame. We incorporate a watchdog entity in our tiered framework to prevent collusive tendencies of potentiality liable entities and to prevent exploitation of evidence. Also, we incorporate a state mechanism to prove the state of a smart vehicle when an accident occurs. Furthermore, we conduct a security analysis to demonstrate the resilience of our framework against identified attacks and describe security mechanisms used to achieve key requirements for vehicular forensics. Finally, we comparatively evaluate our framework against existing proposals.
