IKEv2 authentication exchange model and performance analysis in mobile IPv6 networks

摘要

Internet Key Exchange version 2 (IKEv2) is taking the responsibility for distribution and management of reliable authentication key. IKEv2 can secure fast hand off, confidentiality of data, safe transmission, and multih-oming to transmission node. In this paper, we designed and constructed the network based on real mobile node and experimented the modeling of IKEv2 protocol through the simulation. We analyzed the resetting of authentication key and re-exchange problem. And we experimented the effect that key exchange is affected by a limited bandwidth based on data analysis. To overcome delay time, we proposed multi-interface of node and analyzed performance and latency for authentication setting and exchange process. The simulation results show that re-authentication of key is impossible to reset because of limited bandwidth of network. Also, the use of proposed multi-interface can minimize key exchange latency that happened by hand off for IPSec transmission.
