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.
