Research on Private Key Update of Space Network
Zheng Minghu · 2014
In this paper,we proposed an identity-based hierarchy group key management scheme(ID-HGKM) for the entire space network,using the hierarchical-grouped group key management scheme.In addition to a common group key generation,distribution and update,we also considered the part of the private key update.Using the identity-based key encryption mechanism which is proposed by Boneh and Franklin,we proposed the private key update mechanism for space network.The program can adapt to the hierarchical structure of the space network and meet the requirements of its strong scalability and high reliability.
