A searchable encryption privacy protection method and system based on Internet of Vehicles

Abstract

The invention discloses a searchable encryption privacy protection method and system based on Internet of Vehicles. The method accurately searches the encrypted information of the user in a cloud server under the condition that the user data is encrypted, so as to protect the privacy of the user. Since the data in the Internet of Vehicles contains more private information of the user, especially the characteristic values ​​of the vehicle, this information is transmitted directly in the network in plain text, and the information is easy to be monitored or stolen. At the same time, when the server of the third party is in an unsafe state, the key stored in the server will also be leaked, which eventually leads to the leakage of user information. Therefore, the present invention provides a searchable encryption privacy protection solution based on the vehicle network. The data between the server and the Internet of Vehicles device is encrypted and transmitted, and the server stores the encrypted data without being able to view the data information to ensure the privacy of the user; When the terminal obtains data, it uses encrypted search. During the whole process, the data is encrypted, so as to realize the system security of the entire Internet of Vehicles.

Description

technical field [0001] The invention relates to a searchable encryption privacy protection method and system based on the Internet of Vehicles. Background technique [0002] With the rapid development of mobile communication technology and the increase in user demand for mobile applications, remote control equipment has also been rapidly popularized, especially in the field of Internet of Vehicles, research on autonomous driving technology has always been a hot topic. At the same time, due to the application of cloud computing and cloud storage technology in the Internet of Vehicles, the user's data is basically stored in the cloud server, and the Internet of Vehicles, because of its particularity, often has strong privacy for the user's data. Therefore, how to Effectively protecting the privacy data of users has become one of the key factors in solving the security problems of the Internet of Vehicles. [0003] There are many ways to protect the security of users' private ...
