1. A method of integrating quantum keys and classical keys for IPSec using Security Association (SA) tables and at least one IPSec tunnel, comprising:
a) for each IPSec tunnel, creating an inbound and outbound classic SA pair using a standard Internet Key Exchange (IKE) protocol;
b) creating a final SA pair from the inbound and outbound classic SA pair by combining classic keys associated with the inbound and outbound classic SA pair with quantum keys;
c) repeating b) N times using different quantum keys to generate N final SA pairs; and
d) appending the N final SA pairs to corresponding inbound and outbound SA tables, wherein the classic keys and quantum keys are combined in a microprocessor using microcode embodied in host software stored in a processor-readable memory.
