学生:XXX 指导教师:XXX
内容摘要:随着网络安全问题的日益突出,计算机用户对网络安全技术及其相关产品也越来越关注。在众多的网络安全技术中,核心层封包截获技术有着非常重要的地位,它是包过滤防火墙的基础,并且被广泛的用于封包过滤、协议转换、截取报文分析以及网络嗅探等技术中。因此,本文就核心层网络封包截获技术进行了探究。首先,本文对目前该技术的国内外现状进行了说明,以明确进行研究的目的。随后,详尽地对核心层网络封包截获技术的实现原理作了讲述,在讲述原理时主要介绍了一下几个方面的内容:分层服务提供者(LSP)的相关概念、原理和用途;核心层网络驱动和NDIS网络驱动程序;核心层网络封包截获技术的实现。通过对原理的说明,使读者了解实现这项技术的具体方法。最后,为了实现这项技术并对前面提出的原理进行验证设计了相关的软件,本文对这个软件作了系统分析和系统设计,最终并实现了该软件。通过测试,证明了其具有在核心层截获封包,在应用层分析封包的功能,也验证了本文所探讨的原理的正确性和重要性。

The Technoloty of Packet Interception in Kernel Layers
Abstract: Because work security problems have gone from bad to worse, computer users begin to work security technology work security products. Among all kinds of security technologies, the technology of packet interception in kernel layer is very important for it is the basis for packet filter firewall and it is widely used in packet filtering, protocol conversion, interception of message analysis work sniffering. Therefor, I devote myself to studying on the technology of the packet interception in kernel this article, firstly, the present situation of this technolony is described to tell reader why I study on it. Secondly, principles of packet interception are told about in this detailed description part, the concept of the LSP ,the theory of the LSP and the usage of LSP are introduced in more detail. What’s more, I also explain many aspects of work drivers in kenel layer and tell reader how to implement the , reader can understand the technology of packet interception in kernel layer accurately. Finally, to implement and check out the technology I have discussed, pile the software Filter which is analyzed and designed systematically in this article. By testing , the software can intercept packets in kenel layer and analyze packet in application layer.
