A system for establishing an encrypted multicast communication session over a communications network can include a client means (e.g., a radio, laptop, workstation, phone, PDA) and a server means. The client means can transmit a request for a first user to join a pre-defined collaborative group, including at least the first user and a second user. The client means can transmit a request for a first user to create or select a collaborative group based on specified criteria. The system can also include a server means that can retrieve, select or generate an encryption key for the collaborative group and transmit the encryption key to the first user via the client means. The server can transmit the encryption key to the second user via a second client means. The client means can communicate via multicast, encrypting end-to-end above the network layer using the encryption key received from the server means.
