摘　　要：高速和准确是入侵检测系统(IDS)的主要指标,入侵检测引擎是基于特征的IDS的重要功能组件,加快入侵检测引擎的检测速度对提高IDS的整体性能至关重要。本文提出了一种有效分割目标文本,且能在并行体系结构下实现的模式匹配的方法。分析表明,新的处理方法能有效提高入侵检测引擎的检测速度。High-speed and correctness are main performance for intrusion detection system （IDS）, and intrusion inspection engine is an important component in specification-based intrusion detection system, it is seriously important to improve the system＇ s entire performance by accelerating the speed of inspection engine. This paper proposes an effective method of cutting the text in ad- vance, and it is easy to apply in the parallelization architecture. Analysis shows that the new method is effective in improving the detection speed of intrusion inspection engine.
