Electric vehicle charging service method capable of protecting privacy

Abstract

The invention discloses an electric vehicle charging service method capable of protecting privacy. Method, the electric vehicle generates a temporary token by using the key pair allocated by the charging service provider and the pseudo identity allocated by the trusted center; authenticating to a roadside unit by using the temporary token; after the authentication is passed, the roadside unit sends a seed key required by the authentication of the charging panel to the electric vehicle; challenge response is carried out by using a disposable session key generated by the seed key to complete authentication; after the authentication is passed, the charging panel provides charging service for the electric vehicle. According to the invention, identity protection of the electric vehicle is realized by adopting the pseudo identity information; the malicious entity is prevented from obtaining the real identity of the vehicle in the charging service process; according to the method, the drivingtrack of the vehicle is exposed, so that the privacy of a vehicle owner is invaded, when the electric vehicle has any improper behavior, the trusted center can reveal the real identity of the electric vehicle, and through the method disclosed by the invention, the behaviors of the electric vehicle can be better managed.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle charging service method capable of protecting privacy. Background technique [0002] As global environmental issues and energy issues become increasingly prominent, the development of new energy vehicles such as electric vehicles has been strongly supported and encouraged by countries all over the world. With its advantages of safe operation, convenient use, low maintenance cost and good user experience, wireless charging technology has received more and more attention, and it is one of the main development trends of electric vehicle power supply technology in the future. However, in the current authentication method for wireless charging of electric vehicles, since the electric vehicle directly uses the real identity for charging authentication, malicious entities can easily obtain the real identity of the vehicle during the charging authentication ...
