| Abstract | In Vehicle-to-Grid (V2G) scenarios, Electric Vehicle (EV) batteries serve as distributed energy resources that help stabilize power supply through managed (dis)charging. The effective and safe grid integration is only possible when an Electric Vehicle Charging System (EVCS) responsible for the battery management and V2G communication is counterfeit-free and protected against malicious attacks. By manipulating the EVCS, adversaries can cause financial and physical damage and increase the risk of hazardous situations such as fire and traffic accidents. In this paper, we introduce secEVCS, a security architecture for EVCSs, which ensures that only a vehicle with a manufacturer-approved charging system can connect to the grid by securely binding all components of the EVCS. Our solution is base d on the enhanced authorization functionality of the Trusted Platform Module (TPM) and protects against the installation of counterfeit products and re-use of secret data stored in scrapped EVCSs. We implemented secEVCS using a TPM 2.0 chip and the V2G protocol specified in the ISO 15118 standard to show the feasibility and to evaluate the performance of our solution. |
