Research on Privacy Protection of Internet of Vehicles Based on Elliptic Curve Ring Signature

With the continuous development of new energy vehicles in recent years, the application of the Internet of Vehicles (IoV)has also been rapidly expanded. However, behind the development of this series of technologies, there will also be many security issues has happened. In response to this phenomenon, this paper uses elliptic curve ring signature technology to protect the privacy of messages signed by vehicle users. By hiding their public key in a user group, the other party will not find the information through the signed message. source. Prevent the disclosure of identity and privacy of vehicle users in the process of anonymous voting. The simulation results show that our method is feasible in the Internet of Vehicles (IoV) because it is completely sufficient to support this scheme from the perspective of time.
