| Abstract | In recent years, the intelligent transportation system has become an inseparable component for the smart city ecosystem. Through information sharing among the entities in the ITS such as roadside units, traffic cameras and local controllers, the entire system aims at improving road safety and overall traffic efficiency. However, as drastic amount of data have been exchanged and logged, how could such a system maintain the integrity, authenticity, and non-repudiation of the information for constant verification and audit is one of the biggest challenges. At the same time, as being considered as part of the critical infrastructure, in the smart city ecosystem, the security of the ITS also needs to be addressed carefully. In this work, we propose a novel blockchain-based architecture for ITS, to record actions and information sharing among the entities, at the same time assist in mitigating common types of attacks. Experiments are conducted to assess the overhead of critical cryptographic primitives. |
