摘　　要：构建入侵事件序列模式的挖掘方法,并对其进行隐私保护,对算法进行优化,减少运行周期;采用MSAP方法思路,通过数据预先处理、生成全局攻击序列、构建候选模式数据库、取得最大攻击行为集和最大攻击序列,并加载隐私保护;通过实验证明QSPM算法和PQSPM算法相比原有算法无论从运行周期还是高效性都有明显优势;表明QSPM和PQSPM算法在入侵事件序列模式挖掘方面具有更好的性能。The mining method of the sequential patterns for invasion events is constructed and loaded with the privacy preservation. Algorithm is optimizedand its operating cycle is shorten. All the above is obtained by adopting the MSAP algorithm, data pre -processing, generating the global sequence of attacking, con- structing the database of candidate pattern, obtaining the maximum set of the attacks and the maximum se- quence of attacks, and loading privacy preservation. Experimental results show that the QSPM algorithm and the PQSPM algorithm have obvious advantages over the original algorithm in the aspects of operating cycle and efficiency and the two algorithms have better performance in mining of the sequential patterns for inva- sion events.
