IPSec interworking issues under mobile wireless network scenarios
-
摘要: IPSec能够为固定有线网络环境下的IP应用提供端到端通信安全;未来移动无线网络环境下,仍然可以使用IPSec来保障大量移动无线终端之间的通信安全.在移动无线应用场景中,存在IPSec与其它网络应用协议之间的互操作问题.分析了移动无线应用场景中IPSec和性能提升代理及移动管理等网络协议之间的互操作问题,并给出了可行解决方案;分析了现有IPSec体系结构在移动无线应用场景中体现出的不足,指出了下一代IPSec体系结构发展趋势.Abstract: IPSec protocol can provide end-to-end security for IP-based applicati ons in fixed wired networks; IPsec can also be used to provide communication sec urity for numerous mobile wireless terminal devices in future mobile wireless ne tworks. Interworking issues between IPSec protocol and other network pr otocols should be solved before its wide deployment.The interworking issues betw een IPSec and performance enhancing protocols and mobility management protocols under mobile wireless network scenarios were analyzed, followed by some practica l solutions. The issues related to the current IPSec architecture in mobile wire less networks were analyzed, the development trend of next generation IPSec arch itecture was pointed out.
