Vehicle identity authentication method based on virtual machine migration technology

Abstract

The invention relates to the field of identity authentication of an internet of vehicles and discloses a vehicle identity authentication method based on the virtual machine migration technology. The vehicle identity authentication method based on the virtual machine migration technology comprises the following steps that a mobile on board unit sends an identity authentication request to a road side unit with an identity certificate of the mobile on board unit as a credential, after determining the legitimacy of the identity of the mobile on board unit, the road side unit turns on a virtual machine corresponding to the mobile on board unit, and identity relevant information of the on board unit is stored in the corresponding virtual machine; based on the position information of the on board unit, the current road side unit can determine the migration address, corresponding to the virtual machine, of the on board unit, namely, the network address of a target road side unit; when the connection between the on board unit and the current road side unit is interrupted and the on board unit is connected to the target road side unit, and the target road side unit detects the corresponding relation between the identity relevant information stored in the current virtual machine which is turned on and the identification certificate of the on board unit which requests identity authentication so that the identity legitimacy of the on board unit can be determined; the on board unit can have access to the virtual machine corresponding to the migrated on board unit through the target road side unit.

Description

[0001] technical field [0002] The present invention relates to the field of identity authentication of the Internet of Vehicles, and more specifically, to a fast identity authentication method based on virtual machine migration technology. Background technique [0003] Internet of Vehicles (IOV: Internet of Vehicle) is a segmented application of the Internet of Things in the automotive field. It is the only way for the mobile Internet and the Internet of Things to develop into business essence and depth. The development of convergent technology. It can realize information sharing through vehicle-to-vehicle, vehicle-to-people, vehicle-to-road interconnection, collect information on vehicles, roads and the environment, and process, calculate, share and securely release the information collected from multiple sources on the information network platform , effectively guide and supervise vehicles according to different functional requirements, and provide professional multimed...

Problems solved by technology

On the issue of the identity authentication of the vehicle-mounted unit, most of the solutions adopt the method of starting a new handshake authentication process every time the vehicle-mounted unit enters a new roadside unit. In these solutions, the roadside unit is generally used for identity authentication of the vehicle-mounted unit. The overhead of the algorithm is too large, and it cannot adapt to the problem of heavy traffic and heavy load; only a few schemes mention the problem of identity switching between the on-board unit and the roadside unit, but do not mention the basic storage necessary for the implementation process Specific forms of transfer of facilities and identity-related information

In general, traditional solutions are still not mature enough and practical
