1. A cryptographic key management system for providing secure communication in a cryptographic system, said cryptographic key management system comprising:
a plurality of communication apparatuses under the control of a common control console, each communication apparatus being in communication with at least one source of dynamic random or pseudo-random information via the common control console; and
communication paths among the plurality of communication apparatuses, said communication paths including a control plane, an entropy plane and a data plane, the entropy plane being in communication with a multi-dimensional storage array of the control console, the multi-dimensional storage array for storing source entropy data that is indexed in discrete quantities, each discrete quantity being stored for single use, the common control console providing the stored entropy data from the multi-dimensional storage array to the plurality of communication apparatuses using the entropy plane, the data plane providing secure communication in the cryptographic system using stored entropy data from the multi-dimensional storage array.
