嵌入式无线局网检修管理系统的安全机制研究

Research of Embededder WLAN in Overhaul Management Systerm＇s Security Mechanism

基于嵌入式无线局域网（WLAN）的企业检修管理系统中，WLAN虽然克服了有线网络存在的不足，增强了网络对环境的适应性，而且提供了良好的可移植性和可配置性，但也暴露出诸多安全问题，该文提出了将IEEE 802．1x可扩展认证协议（extensible authentication protocol，EAP）与VPN的因特网协议安全（Internet Protocol Security，IPSec）相结合的方案来构建安全的无线局域网，建立一个高效、安全的管理系统。

In the based on embedded wireless local area network （WLAN） the enterprises overhaul management system, Although WLAN have overcome deficiencies of cable network, enhance the network adaptability to the environment, provide a good portability, and configurable, but WLAN has also revealed many security issues. The paper proposes solution of associating IEEE 802.1x EAP with VPN IPSes resented to build a secure wireless LAN, build an efficient and safety management system.
