【摘要】：随着无线通信技术的不断发展,无线局域网已经得到了越来越广泛的应用,并已成为计算机网络中重要的一部分。但因其输介质的特殊性,无线传输的介质是共享的。所以相对于有线网络来说,无线局域网发送和接收数据更容易被窃听,无线局域网的安全问题成为一个阻碍其发展的障碍。……本论文正是从分析无线局域网现阶段所存在的的安全问题作为出发点,并以出发点为基础,将实现无线局域网内安全为本篇论文主要的研究对象。主要是在IPsec(Internet Protocol Security)协议族的基础上对其端对端传输的数据安全传输技术作了创新性和探索性的研究,其内容主要表现在一下几个方面:1.详细研究了无线局域网发展的现状和目前存在的问题,国际上和我国在无线网络领域发展的现状和前景。……2.详细研究了无线局域网使用的网络协议的原理和协议算法中存在的缺陷,以及这些缺陷可能导致的安全性问题。……3.研究了协IPSec协议族的相关技术,详细研究了协议族中有关保护分组流的协议,包括该协议中的封装安全载荷协议和认证头协议协议,用于保证数据的机密性、可靠性和完整性。……4.研究以IPsec技术实现主机间端到端的安全性数据传输,从而提供了使无线局域网间的安全通信的新方式。……
[Abstract]:With the continuous development of wireless communication technology, WLAN has been more and more widely used, and has become an important part of computer network. However, due to the particularity of the transmission medium, the medium of wireless transmission is shared. Compared with wired networks, WLAN is easier to eavesdrop on sending and receiving data, and the security of WLAN becomes an obstacle to its development. This thesis is based on the analysis of the security problems existing in WLAN at the present stage and takes the realization of WLAN security as the main research object. On the basis of IPsec (Internet Protocol Security) protocol family, this paper makes an innovative and exploratory research on the data security transmission technology of end-to-end transmission. The main content of this paper is shown in the following several aspects: 1. The present situation and existing problems of WLAN are studied in detail, and the present situation and prospect of WLAN in international and China are also discussed. In this paper, the principle of the network protocol used in WLAN and the defects in the protocol algorithm are studied in detail, as well as the security problems caused by these defects. In this paper, the related technologies of the coIPSec protocol family are studied in detail, including the encapsulation security load protocol and the authentication header protocol, which are used to ensure the confidentiality, reliability and integrity of the data. This paper studies the implementation of end-to-end secure data transmission between hosts using IPsec technology, which provides a new way of secure communication between WLAN.
