A New Secure Group Correspondence Mechanism in Space Network
Xuehui Du, Xingyuan Chen, Yadi Wang, Daowen Hua · 2009
The space network has long delay, low useable width, limited computation ability and so on, however, the group correspondence among nodes can save the transmission bandwidth and reduce the network load effectively, therefore the group correspondence becomes extremely important in the space network application. But the SCPS-SP protocol that CCSDS issued can only provide the end-to-end secure transmission, cannot guarantee the group correspondence security. As a result how to realize the secure group correspondence in space network becomes research hot spot in space transmission.
