Embodiment Construction

[0041] The technical solution of the present invention will be described in detail below in conjunction with the drawings.

[0042] The present invention provides a method for changing pseudonyms in the Internet of Vehicles based on game analysis, which is specifically implemented as follows:

[0043] 1. Vehicle registration stage

[0044] Before the vehicle is connected to the Internet of Vehicles, it must first register with the certification center and register the vehicle information, such as figure 2 As shown in ①. The certification center will allocate M pieces of identity information for each vehicle, and each identity information contains {PK i k ,SK i k ,Cert i k }, k=1,2,...M, such as figure 2 Shown in ②.

[0045] Among them, PK and SK are public and private key pairs, and Cert is the certificate issued to the identity by the certification authority. In addition, the public key PK is the pseudonym described in the present invention, which can uniquely identify a vehicle, ...

Abstract

The invention relates to an Internet of Vehicles pseudonym replacement method based on game analysis. On the basis of a mixed region mechanism, a game analysis method is introduced into the method tosolve the problem of privacy personalized protection, that is, under the condition of giving track entropy and attacker ability, an optimal pseudonym replacement strategy is selected by solving Nash equilibrium in attack and defense games. According to the method, the high anonymity of the vehicle moving track is ensured, the pseudonym replacement frequency of the vehicle can be reduced, and the service quality is improved.

Description

Technical field [0001] The invention belongs to the field of vehicle pseudonym replacement in the Internet of Vehicles, and particularly relates to a method for replacing pseudonyms of the Internet of Vehicles based on game analysis. Background technique [0002] With the rapid development of mobile Internet and automobile manufacturing, the Internet of Vehicles has become an inevitable trend in the current automobile industry. The Internet of Vehicles is a self-organizing network established by moving vehicles through on-board units and roadside units. The structure of the Internet of Vehicles such as figure 1 As shown, the vehicle is a mobile unit with a wireless communication function, and the roadside unit is a network infrastructure deployed on the roadside (acting as a router function), and the channel between the two uses a dedicated short-range communication frequency band. In the Internet of Vehicles environment, vehicles can directly exchange information with neighbori...
