| 摘 要： | IEEE 802.11无线局域网已得到了广泛的部署.在无线局域网中,终端移动时经常发生切换,需要进行安全认证,这导致较长的处理时延,降低了服务质量.目前的认证方法,如AAA和IEEE 802.1x,不能支持低时延切换.本文提出了一种两级认证方法,移动终端在快速切换协议中可以执行认证.在漫游到新域之前从目标接入点获取一个临时身份,通过使用该临时身份继续认证快速接入.移动终端在短时间内必须执行再认证,以便完成正常的认证过程,否则,认证接入将被终止.仿真结果表明,本文提出的两级认证方法在切换过程中显著地减少了切换时延和丢包率.

| Abstract: | IEEE 802.11 WLANs are widely deployed nowadays.While a mobile device is moving around,it may need to do handoff that usually requires authentication,this results in long processing delay and leads to degradation of quality of services provisioned to the mobile device.Existing authentication methods such as AAA and IEEE 802.1x mechanisms are unable to accommodate low-latency handoff.In this work,we propose a two-stage authentication approach that allows a mobile device to perform authentication through fast ... |
