摘　　要：提出一种应用于无线局域网的快速安全切换方案,它通过对邻接接入点的提前认证,可以减少切换时无线用户的重新认证时间;同时,漫游密钥和对主密钥的频繁更新可以保证切换安全.分析和仿真结果表明,该方案具有很低的切换时延,而且安全性较高.A fast and secure handoff scheme for wireless LAN was proposed. In this scheme, APs adjacent to the AP that is associated with the wireless client are pre-authenticated by the RADIUS authentication server, hence to reduce the time consumption of re-authentication between those APs and the wireless client. In addition, synchronous rekeying of pairwise master key and roaming key can secure the handoff process. The analysis and simulation show that the proposed scheme is efficient in terms of handoff delay as well as security.
