摘要
随着信息技术和数据技术的飞速发展,从大量的数据中获取有用的信息和知识变得越来越重要。聚类分析和关联规则挖掘是数据挖掘中的核心技术。文中基于数据挖掘技术和口令因子的概念,提出一种崭新的用户口令字典生成方法,通过对原始的用户口令进行数据挖掘,分析在用户口令中所隐含的口令因子关联规则,将所获得的口令因子关联规则成功地应用在用户口令字典生成中,并在WinRAR文件破解中取得了良好的效果。
With the rapid development of information technology and database technology,the mining of valuable information from abundant data becomes more important. Cluster analysis and association rule mining are core technology of data mining. A novel method to generate password dictionary based on data mining technology is proposed. Through mining the user password data and analyzing the association rule of password factories,the knowledge acquired from data mining is successfully applied to the generation of password dictionary and realizes high performance in brute-force attack.
