An authentication method and system for privacy protection of dynamic wireless charging of electric vehicles

Abstract

The invention belongs to the field of security authentication in the discipline of cyberspace security, and specifically relates to an authentication method and system for privacy protection of dynamic wireless charging of electric vehicles, including: registering an electric vehicle with a vehicle management office, obtaining a login password for an anti-tampering device of the vehicle, Log in to the anti-tampering device afterwards to generate a false identity and request an authentication token from the charging service provider, which enables the electric vehicle to pass the authentication of the roadside unit and obtain a one-time session key for authentication with the charging board; the present invention guarantees It improves the efficiency, identity privacy and location privacy of electric vehicles during charging authentication, and in case of disputes, with the assistance of multiple vehicle management offices, charging service providers can recover the true identity of the vehicle, ensuring the identity of the vehicle Not in the hands of any trusted third party.

Description

technical field [0001] The invention belongs to the field of safety authentication in the discipline of cyberspace security, and in particular relates to an authentication method and system for privacy protection of dynamic wireless charging of electric vehicles. Background technique [0002] With the intensification of environmental pollution and the depletion of fossil energy, electric vehicles have been vigorously developed. The dynamic wireless charging technology for electric vehicles enables electric vehicles to be charged while driving through the magnetic induction between the charging pad placed under the road and the transmission coil at the bottom of the vehicle. When EVs are connected to the grid during periods of rapid movement, it must be possible to preserve their identity and location privacy while effectively authenticating them. Dynamic wireless charging technology will provide better development prospects for electric vehicles. However, dynamic wireless c...

Problems solved by technology

However, the Internet of Vehicles focuses on secure message authentication. In the dynamic wireless charging scenario with identity authentication as the core, the purpose and efficiency of authentication may be different.

In addition, the existing identity-based CPPA scheme still relies on a trust center to know the real identity of the vehicle in identity tracking, if the trust authority is destroyed, the whole system will face a high risk of privacy leakage
