ABSTRACT

When EVs are charging and discharging or enjoying other services, it is crucial to protect the communication data between electric vehicles and charging service control centers. Guaranteed confidentiality and y-verification of information, and it takes a long time to verify when a large number of EV users are signing confidentiality at the same time. For those problems. We proposes a certificate-free aggregated signcryption scheme for V2G based on the assumption of Diffie-Hellman difficulty problem. A bilinear mapping operation is used to add the identity information of EV users and charging service companies into the signature and ciphertext respectively to hide the user identity information. In the aggregation verification phase, only two fixed bilinear mapping operations are used, which can effectively improve the computational efficiency.
