  Abstract: This paper deals with the design of the secure network of the Enhanced Internet of Vehicles by using the Blockchain Governance Game. The BGG is the system model of the stochastic game to find best strategies towards preparation for preventing a network malfunction by an attacker. The paper applies the stochastic game model into the connected vehicle security. Analytically tractable results for decision making parameters are fully obtained which enable to predict the moment for safety operations and to deliver the optimal combination of the number of reserved nodes and the acceptance probability of the backups to protect the Blockchain enabled IoV network in a connected car. This research helps for whom considers the enhanced secure IoV architecture with the BGG within the decentralized network.
