Traceability for Vehicular Network
Real-Time Messaging Based on Blockchain Technology National Taiwan University, 10617 Taipei, Taiwan
Abstract Autonomous vehicles are capable of navigating without
any intervention of human based on onboard sensor data and wayside sensor
data. However, when an incident occurs, responsibility and liability must be
indubitably decided based on those data received by vehicle in the past.
Without those data or if the stored data is incorrect, one cannot reproduce
the accident’s scene correctly which will lead to incorrect result of
accident forensic process. Therefore, we need a secure and real-time data
logging system to record the data received by each vehicle. In this work, we
propose a secure, real-time, and distributed data logging system with higher
fault tolerance and scalability based on Blockchain
technology, which enables autonomous vehicles log every data they received in
real-time and ensure data integrity. In addition to Blockchain
technology, digital signature and cryptography hash function are also
included in our proposed system in order to detect if the stored data has
been tampered. If the data is tampered, the system is able to detect the time
period during which the data is tampered. With these properties, our system
is capable of deploying in VANET and the stored data will be secure and
reliable. Keywords: Vehicular network, block-chain,
traceability. +: Corresponding author: Chi-Sheng Shih
