摘要
随着无线局域网(WLAN)应用规模不断扩大,其通信安全问题备受业界关注。通过分析现有的WLAN在物理层、数据链路层和网络层三个层次的安全机制,从访问控制和数据加密两个方面指出了其局限性和缺陷,提出了运用隔离技术、升级加密方案和VPN技术等措施构建多层次的安全体系,确保WLAN通信安全。
With the development of wireless LAN,people pay more attention to the communication security.The limitation and flaw about access control and data encryption are pointed out on the basis of analysis of the safety mechanism in phy-sics layer,data link layer and network layer.A multilayer safety system built by isolation technology,upgrade encryption and VPN technology is put forward to ensure the communication security.
