Embodiment Construction

[0050] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0051]In the V2X network, each node regularly broadcasts heartbeat information including its own status information such as geographic location, status, unique identifier, and driving direction to surrounding nodes. In the case of , communicate with surrounding nodes. With the help of heartbeat information regularly broadcast between nodes, it is possible to form a group of vehicle nodes within the communication range, initiate group password negotiation, monitor the sending of group negotiation messages, and group maintenance, etc., and then complete the group password Negotiation process to ensure secure communication between vehicle nodes in the group.

[0052] figure 1 It is a flow chart of the method of the present invention. As shown in the figure, the group password negotiation method based on the vehicle-mounted short-distance commu...

Abstract

The invention discloses a group password negotiation method based on a Vehicle to X (V2X) network. The method comprises: an initiating node broadcasts a negotiation operating message comprising a group communication queue to surrounding nodes agreeing to join a group, vehicle nodes sequentially generate and broadcast negotiation password messages according to the sequence of unique identifiers of the surrounding nodes in the group communication queue, the initiating node generates and broadcasts a final negotiation password message after receiving the negotiation password message of the last vehicle node, and the surrounding nodes generate group passwords using the final negotiation password message, thereby realizing secret communication with the vehicle nodes in the group. By using the characteristics of the V2X network, the method realizes a group password negotiation process among the vehicle nodes and ensures secure communication among the vehicle nodes.

Description

technical field [0001] The invention relates to a group password negotiation method based on a vehicle-mounted short-distance communication network, and belongs to the technical field of vehicle-mounted communication networks. Background technique [0002] The vehicle short-distance communication (VehicletoX: V2X) network is realized by short-distance communication technologies such as wireless communication, GPS / GIS, and sensors. 2-Vehicle), outside the vehicle (vehicle-2-Infrastructure), and between vehicles (Vehicle-2-Person). [0003] As a wireless mobile network with constantly moving vehicles as the core node, V2X has the characteristics of rapid change in topology structure, especially the opening of its communication medium leads to poor channel security, and is more vulnerable to attacks than traditional networks. At the same time, since V2X is the core of the future intelligent transportation system (ITS), it involves high-security applications such as safety and ...
