Abstract

The invention relates to the technical field of vehicle-mounted network communication security, in particular to an SDN-based vehicle-mounted cloud computing method with privacy protection, which comprises the following steps: constructing an SDN-based vehicle-mounted cloud computing system, and applying for registration in the system and obtaining a resource certificate by a new vehicle; the vehicle-mounted cloud initiator selects the verified vehicles from the vehicles to form a vehicle-mounted cloud, numbers the selected vehicles and the vehicle, and negotiates vehicle-mounted cloud keys for all the vehicles in the vehicle-mounted cloud; when other new vehicles want to join the vehicle-mounted cloud, the vehicle-mounted cloud initiator verifies the validity of the resource certificate of the new user and then numbers the vehicles, and negotiates the vehicle-mounted cloud key again; when a member in the vehicle-mounted cloud leaves, the member leaving the vehicle-mounted cloud sends a leaving message to a neighbor vehicle of the member, and the key of the vehicle-mounted cloud is negotiated again; according to the invention, all vehicle nodes cannot confirm the real identity of the sender through the message and cannot track the position information of the vehicle through the link message.

Description

technical field [0001] The invention relates to the technical field of vehicle network communication security, in particular to an SDN-based vehicle cloud computing method with privacy protection. Background technique [0002] In the Internet of Vehicles environment, vehicles can obtain useful data and efficient applications through the interaction between vehicle-to-vehicle (V2V, vehicle-to-vehicle) and vehicle-to-infrastructure (V2I, vehicle-to-infrastructure). However, the complexity of the road environment poses challenges to the computing and storage capabilities of a single vehicle, and the vehicle cannot process massive and time-sensitive data in a timely manner. Vehicle cloud computing (VCC, vehicular cloud computing) combines vehicle networking and cloud computing technologies to aggregate underutilized vehicle resources to form a temporary "cloud", and dynamically allocate available resources to authorized vehicles. VCC can provide efficient technical support for ...
