| 摘 要： | 无线技术WiFi与VoIP的结合已成为当今通信领域的热点话题,但是安全隐患的问题却一直存在。安全隐患将是制约WiFi应用发展的瓶颈,而基于802.11b无线网络的首个安全协议——有线对等式加密(WEP)存在很多漏洞,因此WiFi联盟提出了一系列加强无线网络安全的新举措。文章详述了WEP协议的缺陷,着重分析比较了TKIP、CCMS以及802.1x等新型无线网络安全方案与WEP的差异,并对无线VoIP安全方案提出了新设想。

| Abstract: | The combination of WiFi and VoIP has been a hotspot in the communication areas. However, security problems have existed all along in this field. Security problems has become the bottleneck to restrict the development of WiFi, But the initial security solution for 802.11b-based network, Wired Equivalent Privacy (WEP), has various technical failures in itself. So the WiFi alliance has put forward a series of new solutions to strengthen the wireless network security. This article describes in detail the limitations of WEP, analyses and compares the differences of TKIP, CCMS 802.1x and WEP,and conceives a new solution about wireless VoIP security. |
