摘　　要：无线通信不受地理位置和空间限制,使用便利,灵活高效。但因其天然的开放性特点,无线网络较有线网络更易受到病毒和恶意程序的攻击,从而面临更为严重的安全威胁。对无线网络安全态势的模拟和分析是提升其威胁防御能力的关键因素。引入概率元胞自动机对无线环境下恶意程序的传播过程进行建模,给出节点行为的形式化表述,通过迭代模拟算法对属性断言的满足情况进行验证,仿真结果表明该方法有望为无线网络安全态势分析及事件响应提供有效的决策支撑。Wireless communication,with no geography or space limitations,is easy in use,flexible and effi-cient. However, due to its openness nature, wireless network is more vulnerable to attacks initialized by viruses and malwares, and thus is encounted with more serious security threats. The simulation and analysis of wireless network security situation is the key factor to enhance its defense capability against potential threats. By introducing probabilistic cellular automata and modeling malware propagation in wireless envi-ronments, the formal description of node behavior is given, and the satisfaction of property assertionsis ver-ified via the iterative automata algorithm. Simulation results indicate that the proposed method could pro-vide decision support for wireless network security situation analysis and incident response.
