Embodiment Construction

[0040] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0041] Such as figure 2 The described embodiment is a vehicle location privacy protection method for a vehicle-mounted ad-hoc network. The vehicle-mounted ad-hoc network uses a terminal set on a car as a mobile node. The terminal includes a wireless transceiver module, a microprocessor, and a memory; the microprocessors are respectively It is electrically connected to the wireless transceiver module and the memory; the mobile node is wirelessly connected to 4 vehicle-mounted servers, and the vehicle-mounted server and the control server are connected wirelessly; including the following steps:

[0042] In step 100, the hybrid area criterion for vehicle i is set in the on-board server as follows: there is at least Vehicles; where i is the number of any vehicle in the on-board ad hoc network; The range of values ​​is: kΔT-Δt≤tchp =0.5, DL i (t)=2.0; k=50;

Abstract

The invention discloses a vehicle position privacy protection method of a vehicular ad hoc network. The method comprises the following steps: a privacy model is first set to assess a current position privacy of different vehicles so as to reflect a reputation module and a mix-zone criterion of a cooperation degree of the current vehicle; any one vehicle in the vehicular ad hoc network determines whether to cooperate and change a pseudo name to protect a vehicle i according to a current reputation value of the vehicle i sending a pseudo name request and based on a judgment whether the one vehicle is within a mix-zone of the vehicle i; and the reputation value of the one vehicle can be dynamically adjusted according to the current position privacy of the one vehicle and pseudo name residual time. The method of the invention can meet the requirement of protecting the current position of the vehicle and can substantially reduce the energy cost; and the method has the advantages that more vehicles are involved in the pseudo name change and the safety of the position privacy of the vehicular wireless network is greater.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a vehicle location privacy protection of a vehicle-mounted self-organizing network that can effectively protect the location privacy of vehicles; can encourage more vehicles to participate in pseudonym changes, thereby significantly improving the location privacy security of the network method. Background technique [0002] With the rapid development of key technologies such as wireless communication technology, vehicle embedded computing, and various vehicle sensors, the vehicle ad hoc network (VANET) is considered to be a very large-scale mobile ad hoc network with a high degree of practicality. The vehicle-mounted self-organizing network is a safe, fast, effective, and open-structure intelligent transportation system composed of vehicle-to-vehicle, vehicle-to-roadside unit (Roadside Units, RSUs) mutual communication, which can realize accident warning, assis...
