ABSTRACT:
A system for secure multicast including at least one sending entity operating on a sending computer system, the sending entity with a sending multicast application running on the sending computer system. A number of receiving entities each running on a receiving computer system, the receiving entities having a receiving multicast application running. A traffic distribution component coupled to the sending entity and each of the receiving entities, where the traffic distribution component supports a connectionless datagram protocol. A participant key management component operates within each receiver entity where the participant key management component holds a first key that is shared with the sender and all of the receiving entities, and a second key that is shared with the sender and at least one but less than all of the receiving entities. A group key management component is coupled to the traffic distribution component and includes a data structure for storing all of the participant first and second keys.
