Privacy Protection Technology for Internet of Vehicles

Abstract

In the context of increasingly improved transportation infrastructure and increasing difficulty in vehicle management, vehicle networking technology has emerged in the public eye. Through rapid development in recent years, the Internet of Vehicles has formed a relatively stable system structure. Subsequently, the risk of attacks on the Internet of Vehicles continues to increase, and the weak password authentication and weak encryption of traditional Internet of Vehicles are no longer able to meet the current privacy protection requirements in the field of Internet of Vehicles. In order to solve the problem of information security in the Internet of Vehicles, privacy protection technology for the Internet of Vehicles was studied in the article. Firstly, the existing security risks of the Internet of Vehicles were introduced, followed by a specific analysis of privacy protection technologies such as Identity-Based Cryptograph, key management technology, and multi-dimensional authentication technology. Then, based on the development trend of existing technologies, the future development direction was predicted, and finally, the current privacy protection technologies for the Internet of Vehicles were summarized.
