Abstract

The invention discloses a VANET privacy protection method under a mobile cloud service. Aiming at the shortcomings of an existing VANET privacy protection method, the invention proposes the VANET privacy protection method under the mobile cloud service, according to the method, the location and trajectory privacy of a vehicle can be protected through a method of dynamically dividing group areas, and a set of comprehensive index is also proposed to measure the location and trajectory privacy. According to the scheme of the invention, on the basis of satisfying the high real-time requirements ofa cloud service VANET, the problem of location and trajectory privacy protection in the VANET can be simultaneously solved by adopting a method of dynamically generating the group areas.

Description

technical field [0001] The invention belongs to the technical field of Internet of Vehicles, and in particular relates to the design of a VANET privacy protection method under mobile cloud services. Background technique [0002] Through the Internet of Vehicles technology, the mobile terminal of the car is connected to the core network of the cloud center through the wireless network (5G, 4G, WiFI) to form a Vehicular Ad-hoc NETwork (VANET), thus providing people with Mobile cloud service VANET: It can not only effectively improve driving safety, but also promote the application expansion of smart cars and promote the development of vehicle applications. [0003] With the increasing number of connected devices and users' high requirements for mobile data volume and speed, 5G wireless communication network technology has become a current research hotspot. The future 5G can provide all types of applications / systems correctly and efficiently at any place and any time, and grea...
