The research on secure communication technics based on IP multicast
Yang Ru · Journal of Heilongjiang Institute of Technology · 2012
IP multicast is an efficient communication technic to send a message to multiple receivers.But the security of multicast hinders it's wider application.The principal problem that multicast confronted with and secure communication technics that should be adopted were recommended.Key management that the core issue of multicast security mechanism was studied.A mixed architecture of group key management was submitted.The architecture can efficiently avoid single-point fault,and enhances the robustness of the system.Then group key managenent simple policy based on subgroup key management and updating algorithm were brought out.Especially,group members' joining and leaving can be efficiently handled,the burdens of key management center were reduced too.
