Abstract
This paper suggests a context-based secure handover mechanism for the frequent handover problemof satellite access nodes due to its high-speed motion in Space-Ground-Integrated Network. Thisapproach applies Private Key Generator (PKG) in identity-based cryptography for key managementand distribution to evade the transport, verification, storage, and other overheads of certificates inPublic Key Infrastructure(PKI), and its context mechanism transmits the authentication informationand session key of the specific mobile node in advance to the next satellite access node, therebyavoiding the delay and communication interrupt due to recertification during a handover, optimizingthe handover efficiency, and guaranteeing the session continuity.
