Vehicle-to-everything (V2X) aims to make transportation system more intelligent through linking everything with the moving vehicles, but it brings geographical dynamic intrusions. However, existing intrusion detection systems (IDSs) of vehicles just deploy the preset statics strategies. As a novel security technology, blockchain can realize decentralized tamper-resistance. However, it has not been used for IDSs because of its rigid structure. In this article, we propose Micro-Blockchain based geographical dynamic Intrusion Detection, MBID, for V2X. A novel nested micro-blockchain structure is proposed, where each micro-blockchain deployed in a small region can construct local intrusion detection strategies for vehicles with tamper-resistance. When a vehicle moves to another region, spatial-temporal dynamic IDSs strategies are constructed through the proposed repeatedly nested scheme for micro-blockchains. Moreover, the control plane is proposed to dynamically configure IDSs strategies into the micro-blockchain. Simulation results show the accuracy of MBID.
