A Secure Solution of V2G Communication Based on Trusted Computing

Aiming at the security problems existing in the communication process of electric vehicles in V2G networks, we propose a secure solution of V2G communication based on trusted computing. The electric vehicle communication is divided into two scenarios, including V2G communication outside the coverage of the aggregation and V2G communication within the coverage of the aggregation. V2G communication outside the coverage area of the aggregation uses onion routing technology to construct an anonymous communication link. And through the embedded trusted computing module to assist in the selection of the communication intermediate node, combined with the signcryption technology to complete the signature and encryption of the communication message. The V2G communication within the coverage of the aggregation completes the mutual authentication of the two parties through the embedded trusted computing module to ensure the trusted connection between them. The safety assessment of related technologies proves that the scheme can meet the security required for electric vehicles' communication.
