摘要
基于内容的过滤技术是反垃圾邮件技术中最有效的方法,但是垃圾邮件发送者千方百计利用各种方法对基于内容的垃圾邮件过滤器进行攻击,严重影响了过滤器的正确率和健壮性。在介绍主要基于内容的垃圾邮件过滤技术基础上,分析了针对基于内容垃圾邮件过滤器的常用攻击方法,并提出了相应的过滤改进技术。同时,针对单词沙拉攻击,在几种过滤器上进行了模拟攻击实验。最后分析了垃圾邮件技术的发展趋势和未来反垃圾邮件技术的主要改进方法。
The content-based technologies are the most efficient means in the anti-spam technologies. However, spammers＇ leave no stone unturned to make use of many kinds of approaches to attack the content-based spare filters, and thus greatly influence spam filters＇ accuracy and robustness. Based on an introduction of main content-based spam filtering technologies, the main attack means that the spammers use to attack content-based spare flters is analyzed, and the corresponding filtering improvement technologies are put forward. At the same time, it does simulation attack experiments in some kinds of filters concerning the word salad attack. Finally, the development trends of spam technologies and the improvement methods of the future anti-spam technologies are analyzed.
