Abstract

Traffic data collection plays an essential role in the operation of connected autonomous vehicle (CAV). The vehicles rely on authentic, accurate and immediate data to make informed decisions about the most efficient and safest routes for delivering passengers. Basic safety messages (BSM) can serve as a source for traffic data collection, as they contain comprehensive data from CAVs. Also, the rapid generation rate of the BSMs ensures the timely of the relevant traffic data. However, given the design of BSM. They are susceptible to various types of attacks, which can be easy to execute. In this thesis, we have developed a method to ensure the authenticity and integrity of BSMs using a decentralized approach: Proof-of-Presence (PoPr). This blockchain system is operates based on proof-of-reputation. The architecture of PoPr is throughly introduced in this thesis, and the simulation results and analysis of the PoPr are provided to illustrate the effectiveness of the system.
