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.

System and method for key distribution in a hierarchical tree

A system and method for generating a plurality of authentication tags using a plurality of authentication mechanisms is disclosed. The plurality of authentication tags can reflect different authentication strength-performance levels. It is a feature of the present invention that a receiver is afforded increased flexibility in adaptively choosing strength-performance levels. It is a further feature of the present invention that multiple authentication tags can be used in multicast environments, where different receivers may have different processor capabilities or security policies.

System and method for enabling authentication at different authentication strength-performance levels

A system and method for detecting and correcting errors using an authentication mechanism is described. In particular, a reversible inner function is used in a nested message authentication code configuration to provide both error detection and error correction in high performance applications.
