摘　　要：博弈论是认知无线电技术的重要分析工具。数据伪造攻击是认知无线电网络中物理层面临的一种安全威胁,在这种攻击中,攻击者向其他次用户发送虚假的主用户感知数据,进而干扰合法次用户利用空闲的频谱。结合军用认知无线电网络的应用背景,利用信号博弈理论对数据伪造攻击进行建模,建立博弈模型并最终得到了均衡的条件。最后对实验结果进行分析,验证了模型的有效性。Game theory is an important analytical tool of cognitive radio technology. The data falsification attack is a securi-ty threat that the physical layer of cognitive radio networks is facing,by which the attackers transmit false perception data of the master user to other secondary users to disturb legal secondary users with unoccupied spectrum. The game theory for signal is ap-plied to building data falsification attack model in combination with the application background of military cognitive radio net-works. The game model was built and the equilibrium condition was obtained finally. The experimental results are analyzed and the model availability is verified.
