Embodiment Construction

[0019] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0020] A vehicle auxiliary authentication method in a vehicle networking environment of the present invention, such as figure 1 shown, including the following steps:

[0021] Step 1: According to the actual traffic situation, establish the OBU computing resource index of the vehicle to be certified;

[0022] In the actual traffic environment, the driving situation of the vehicle is complex, the vehicle speed, traffic density, and the number of vehicles within the DSRC (Dedicated Short Range Communications) communication range of the vehicle are constantly changing. Such changes must have corresponding OBU computing resources allocation strategy.

[0023] The vehicles in the vehicle group of the present invention are networked in Ad-Hoc (point-to-point) mode, and the computing power and storage capacity of each vehicle-mounted OBU are regarded as the...

Abstract

The invention discloses a vehicle auxiliary authentication method under the environment of the Internet of Vehicles. This method combines the actual traffic situation to establish a computing resource index, vehicle primary authentication, and vehicle secondary authentication. This method adopts the car-following theory of traffic vehicles, the current mature DSRC communication ranging technology, the OBU commonly equipped on vehicles, the encryption mechanism is RSA, and the threshold allocation scheme, and assigns the authentication calculation process to the OBU on the driving vehicle, so as to share the large The computing pressure of the large-scale Internet of Vehicles realizes low-cost and high-efficiency certification in the Internet of Vehicles environment. At the same time, the method stores the temporary certificate in segments in the vehicle group ad hoc network to facilitate secondary authentication.

Description

technical field [0001] The invention mainly relates to the security authentication of the Internet of Vehicles, and belongs to the field of communication authentication of the Internet of Vehicles. Background technique [0002] "Internet of Everything" is an important feature of the Internet of Things in smart cities in the future. As an important part of the Internet of Things, the Internet of Vehicles will also be used on a large scale in the near future with the rapid development of the Internet of Things. Security and privacy issues have always been the core issues of network security. The security of the Internet of Vehicles is related to traffic safety. On the basis of traffic safety, traffic is guaranteed to run smoothly and efficiently. [0003] The current authentication usually concentrates the authentication computing process in a centralized security center, without considering the actual traffic situation, and the authentication process requires computing resour...
