A Security Context Transfer Method for Integrated Space Network

The context transfer can improve handover performance effectively through avoid performing the entire protocol exchange with the mobile nodes from scratch, so it have received a lot of attention recently. This paper introduced the present research situation of context transfer, and proposed a security context transfer method for integrated space network, that enables authorized security context transfers. This paper also highlights some the security issues, transport reliability, and MPHR selection algorithm, providing suggestions to overcome those issues. The security context transfer (SCT) proposed by this paper integrated predictive transfer with requested transfer that is transparent for mobile nodes. SCT may allow better support for mobile nodespsila mobility and security. SCT also can reduce latency and packet losses, enhanced reliability and avoid the re-initiation of signaling from the mobile node, so that the applications running on mobile nodes can operate with minimal disruption.
