本文介绍在入侵检测应用中采用自适应(数字)预估的设想。在这种应用中由入侵者所引起的激励是一种暂态信号。其基本原理是用自适应数字预估器来消除相关噪声。因此,在没有入侵者引起的激励时,这种方法有助于减少有害的虚警。当有入侵者引起的激励时,它亦能改善信噪比,从而有利于入侵检测。本方法的性能是通过定点运算模拟来进行考核的。因而本文还涉及到采用商用微处理机的相应硬件实现中的某些问题.
This article describes the concept of adaptive (digital) estimation in intrusion detection applications. In this application by the invaders caused by incentives is a transient signal. The basic principle is to use adaptive digital predictors to eliminate the associated noise. Therefore, this approach helps to reduce harmful false alarms in the absence of incentives from intruders. It also improves the signal-to-noise ratio when intruders are motivated, facilitating intrusion detection. The performance of this method is verified by fixed-point simulation. This article also addresses some of the issues in the corresponding hardware implementation of commercial microprocessors.
