REMOTE PRIVILEGE ALLOCATION

by Erwin P. Comer

PROBLEM STATEMENT

In a communications network, multicast groups and national sovereignty restrictions require closed communications. A user may need to be prohibited from joining a multicast group or communicating with another user.

In order to prevent an unauthorized system consumer or user from joining a multicast session or to prevent communications that violate national sovereignty restrictions, the superior ground equipment node in the communications network must have a mechanism that allows it to restrict a leaf's communication privileges.

SUMMARY OF THE INVENTION

The invention involves the superior node of the communications network tree providing permissions to a leaf equipment's trusted component. The communications with the leaf from the superior node will enable or disable message filters pertaining to header information and/or special bits in the protocol data unit in the leaf equipment's trusted compo-

nent(s). The leaf's trusted component(s) would reject any requests from the operator, application, and/or untrusted component of the leaf to join a multicast group or communicate outside of a restricted message boundary.

Providing the superior node has enabled the filters. the leaf's trusted component would allow messages of the subject type to pass to the communications network; otherwise. the leaf's communications through the network would be inhibited.
