摘要： 在分析入侵检测系统和模糊技术的基础上，研究一种基于模糊推理信息融合的Ad Hoc入侵检测系统模型，将模糊系统较高的准确性、明确的针对性、较好的适应性运用于入侵检测系统，克服目前入侵检测系统存在的效率低、灵活性和升级能力有限等缺陷，提高整个系统的安全性和可用性。该文在分析模糊入侵检测系统的基础上对不同簇首信息进行融合，通过模糊技术作出最终的决策，通过融合中心进行入侵状态估计、态势估计、威胁估计。

Abstract: Based on IDS and fuzzy technology, this paper studies intrusion detection system base on fuzzy reasoning information fusion. The model is good at promoting veracity and flexible in IDS. It overtakes some limitation, such as low efficiency, low flexibility, and uneasy to upgrade. This paper studies that fusion center fuses data of all different cluster head of Ad Hoc, and uses fuzzy technology to deduce decision-making. Decision-making of fusion center makes safety evaluation——status of IDS evaluation, situation IDS evaluation, threaten evaluation.

Key words: information fusion, intrusion detection, safety evaluation
