System and method for broadcast environment group key-derivation |
摘要 |
A key generation system is disclosed that provides for the generation of privileged group keys based on the input of a privileged group. The system performing the key generation has stored component keys corresponding to every possible subset X of the unitary set, where subsets X have k or fewer members. The privileged group key is generated for the privileged set by passing ordered component keys of subsets X that do not contain members of the privileged set to a pseudo random function.
