摘要： 基于生物免疫系统中抗体的克隆机制与亲和度变异机制，提出一种可实时改变当前检测器集合的检测器生成算法用于入侵检测系统(IDS)。理论分析和应用结果表明，该算法通过较少的检测器即可检测出大量非自体空间中的异常变化，且能降低IDS系统的漏检率和误检率，提高报警的可信性。

Abstract: Based on the clone and affinity-variation of antibody in Biological Immune System(BIS), this paper presents a detector real-time generation algorithm which can change the current detector set to apply in Intrusion Detection System(IDS). Theoretical analysis and experiments show that this algorithm can require less evolution algebra to detect lots of abnormal change, reduce the false negative rate and false detection rate for IDS, and improve the alarm credibility.

Key words: Biological Immune System(BIS), Intrusion Detection System(IDS), detector generation algorithm, variation
