Traffic accident forensics method based on blockchain

A traffic accident forensics method based on a blockchain is provided. After a traffic accident, the method allows vehicles to carry out a mutual verification and sign a respective accident report. After one of the vehicles verifies with a road side unit, the signed accident report is submitted to the road side unit and uploaded to the blockchain, so as to record the accident report and preventing the accident report from being tampered, and an efficient mutual verification between the vehicle and the road side unit is achieved. The key parameters in the mutual verification process are encrypted based on an elliptic curve algorithm, and thus the security of the whole mutual verification process is improved. A batch verification way for signatures is designed to reduce the compute pressure of a wireless device. Vehicles use dynamic anonymity policies to protect privacy in the forensics method.
