Abstract

The invention discloses a secure interaction method for wireless cooperative communication, comprising the following steps: a source node sends an RTS frame; a cooperative node receives the RTS frame, and extracts channel information between it and the source node; and the cooperative node performs security verification with the source node; Cooperating node and destination node perform security verification; Coordinating node sends HTS frame to source node; Destination node sends CCTS frame to Cooperating node and source node; Normal data communication starts. In this way, the secure interaction method for wireless cooperative communication of the present invention adopts the method of directly performing node security authentication between the cooperative node and the source node, and between the cooperative node and the destination node. Effectively reduces the complexity of security certification.

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 equal to a multiple-input multiple-output (MIMO) antenna system, which is called It is a virtual multiple-input multiple-output antenna (V-MIMO) system that can support a specific capacity for high-speed users. Therefore, this technique is called "cooperative communication". [00...
