Secure access control protocol for multi-source IP multicast
适用于多源IP组播的安全访问控制协议

The current secure access control techniques in IP multicast just implemented the access control to multicast receivers. A novel secure access control protocol MMAC (Multi-source Multicast Access Control) was proposed, which was widely applied to multi-source IP multicast. The secure access control to multicast participants and un-trusted routers was implemented by introducing special managing host and managing channel. The validity and security of MMAC protocol was analyzed at last.
