Abstract

The invention discloses a wireless cooperative communication security interaction method, comprising the following steps: a source node sends an RTS frame; a cooperative node receives the RTS frame, and extracts channel information between the cooperative node and the source node; the cooperation node and the source node perform security verification; the cooperation node and a destination node perform security verification; the cooperation node requires the source node to send an HTS frame; the destination node sends CCTS frames to the cooperation node and the source node; and the source nodestarts at a normal data communication at a corresponding rate according to different transmission modes after the selection of the transmission mode and the cooperation node is completed. Thereby, the wireless cooperative communication security interaction method provided by the invention adopts a mode in which the cooperation node and the source node, the cooperation node and the destination node directly perform node security authentication respectively, so that better security guarantee during the interaction process of the cooperative communication can be obtained, and the complexity of security certification is also effectively reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a secure interaction method for wireless cooperative communication. Background technique [0002] Cooperative communication is a technology that uses mobile relay nodes to increase the capacity of specific users. The principle of this technology is that when all nodes in the cell work in the same frequency band, the system can be decomposed into three types of nodes. The base station is the source node, the specific The user (high-speed user) is the destination node, and other user terminals are relay nodes. All relay nodes can be regarded as the transceiver antennas of specific user nodes, so the network is equivalent to a multiple-input multiple-output (MIMO) antenna system, which is called It is a virtual multiple-input multiple-output (V-MIMO) system that can support a specific capacity for high-speed users. Therefore, this technique is called "cooperative communication". [0003]...
