基于MIPv6的并发执行安全切换优化机制

Concurrently executing mechanism to secure handoff optimization for IPv6-based wireless networks

提出了一种并发执行的安全快速切换方案,通过引入无线共享密钥交换机制,由切换前接入路由器完成绑定更新。在切换前接入路由器的辅助下,并发执行认证、绑定更新和层2切换过程,较好地改善了绑定更新以及认证对切换的影响。建模分析表明,该机制可以在安全与切换效率上达到很好的折中。

This paper proposed a FMIPv6-based concurrently executing handoff method CE-FMIPv6, which integrated wireless shared key exchange （W-SKE） into FMIPv6 and substitutes previous access router （PAR） for mobile node to complete the binding update process. With the assistant of PAR, executed the mutual authentication, binding update and layer 2 handoff simultaneously, and improved the handoff delay caused by binding update and authentication evidently. The modeling analysis indicates that this method can reach a good compromise between security and handoff efficiency.
