【摘要】 随着互联网的迅速发展,利用电子邮件进行不良信息传播的情况越来越严重,给用户带来极大的困扰,因此对网络中的邮件信息进行有效获取已成为当务之急。根据WinPcap抓包原理,研究了基于简单邮件传输协议SMTP(Simple Message Transfer Protocol)及邮局协议POP3(Post Office Protocol 3)传输的邮件信息解析方法,实现了一个基于WinPcap的邮件信息解析系统EIAS(E-mail Information Analysis System)并提出了系统的性能优化方案。本文的研究成果不仅填补了在高速网络环境下邮件正文及附件信息还原方案的空白,更为监控网络中的不良信息提供了参考。更多还原

【Abstract】 As the development of the internet,it has become increasingly serious that a great deal of insecurity information is transmitted through E-mail,which disturbed users so much. Therefore,it is necessary to analysis the content of E-mail. According to the principle of WinPcap,this article discusses the methods of mail information analysis based on SMTP (Simple Message Transfer Protocol) and POP3 (Post Office Protocol 3). Meanwhile,EIAS (E-mail Information Analysis System) based on WinPcap is implemented and a plan of optimizing the performance is proposed. The result could not only fill the blank of proposals of E-mail text and attachment recovery in high-speed traffic network,but also provide a reference for insecurity information monitoring.更多还原
