WAPI与IEEE 802.11i安全协议通信性能分析

Analysis of Security and Communication Performance about WAPI and IEEE 802.11i

网络的安全性及通信性能是用户最为关注、也是最影响无线局域网技术应用的两个方面。然而不同安全协议工作过程的差异化将导致网络性能各不相同。文中在研究无线局域网的两种主要安全协议WAPI和IEEE 802.11i的基础上,分别对其数据吞吐量及用户接入时延这两个最关键的通信性能进行定性和定量分析。分析结果表明WAPI在安全性及通信性能均优于802.11i。文中最后并提出了进一步改进WAPI通信性能的思路。

With increasing demand for wireless issues, for which users show great concern and which LAN, network security and communication performance are two affects directly the application of wireless LAN technology. However, the different process of different security protocol would results in different network performance. This article studies the two main security protocols of WLAN： WAPI and IEEE 802.11i. And a qualitative and quantitative analysis on the performances of data throughput and delay, which are crucial for communication. Analysis indicates that WAPI has better network security and communication performance than IEEE 802. 11i, and some preliminary considerations are given on the existing security protocols.
