摘　　要：博弈论是无线认知传感器网络的重要分析工具。数据伪造攻击是无线认知传感器网络协同频谱感知面临的一种安全威胁,即恶意用户通过向其他用户发送伪造的频谱感知数据,导致汇聚节点做出错误的频谱分配决策。文章列举了无线认知传感器网络数据伪造攻击可能存在的几种场景,给出了协同频谱感知中存在两个次用户的博弈模型,定义了数据伪造攻击中的博弈元素,分析了数据伪造攻击博弈中的贝叶斯均衡,最后给出了数值结果和最优策略。Game theory is an important analytical tool for Wireless Cognitive Sensor Network （WCSN）. As a main security threat in the collaborative spectrum sensing of WCSN, data falsification attack denotes that malicious secondary user send false local spectrum sensing data resulting in incorrect spectrum allocation by aggregation nodes, this paper summarizes several possible scenarios of data falsification attacks to WCSN, presents the game model where there are two secondary users in the collaborative spectrum sensing, defines the game elements in data falsification attacks and analyzes the Bayesian equilibrium in data falsification attacks. In conclusion, numerical results and optimal strategies are given.
