ABSTRACT:
A system and method for reusable efficient key distribution is disclosed. Key distribution is effected through the application of self-repairing groups that obviate the need for key distribution messages in portions of a hierarchical tree. In one embodiment, the self-repairing group is based on a reusable power set.
