Research on the Applicationof Internet of Vehicles Security Technology Based on Blockchain
The rapid development of the Internet of Vehicles has brought many security challenges,and there is an urgent need for a secure and trustworthy network architecture.This paper proposes a multi-level blockchain based security protection system for the Internet of Vehicles,addressing security threats such as identity authentication,data protection,and privacy protection.This system uses blockchain technology to build a secure and trustworthy network environment,utilizes smart contracts to manage vehicle permissions,and protects vehicle privacy through cryptographic mechanisms such as homomorphic encryption and ring signatures.The system simulation experiment shows that the proposed security scheme can effectively resist various security attacks,ensure the reliable operation of the Internet of Vehicles,and provide new ideas and methods for the field of Internet of Vehicles security.
