Connection of Wireless Networks and Security Architecture and Intrusion Detection Techniques of Wireless Networks
[Abstract] This paper first analyses vulnerabilities of wireless networks and introduces WEP protocol. Based on virtual private network techniques, a security architecture for wireless networks is proposed. Moreover, it presents a model of intrusion detection system and strategies for detecting anomaly behaviors.

目前存在的無(wú)線移動(dòng)網(wǎng)絡(luò)有兩種:第一種是基于網(wǎng)絡(luò)基礎(chǔ)設(shè)施的網(wǎng)絡(luò)，這種網(wǎng)絡(luò)的典型應(yīng)用為無(wú)線局域網(wǎng)（Wireless local-area network ,WLAN）；第二種為無(wú)網(wǎng)絡(luò)基礎(chǔ)設(shè)施的網(wǎng)絡(luò)，一般稱之為自組織網(wǎng)。無(wú)線網(wǎng)絡(luò)可用在軍事通信、無(wú)線通信的家庭產(chǎn)品(Home RF)。事故的突發(fā)現(xiàn)場(chǎng)以及人們希望能迅速共享信息的會(huì)議、辦公室等領(lǐng)域和場(chǎng)所。
