1. A method for communicating secure messages in an optical network environment, comprising:

  • generating message content for communication between a source node and a destination node within an optical network;

    converting the message content to an optical communication packet for transmission to the destination node; and

    encoding the optical communication packet for communication across the optical network using a unique code which is known only to the source node and the destination, such that only the destination node will be able to decode the encoded communication packet and others on the optical network will not recognize the encoded packet, wherein the unique code identifies a plurality of particular optical wavelength/time pairs and wherein the optical communication packet is encoded at these particular wavelength/time pairs.
