Abstract
A system and method for securing communications over a wave division multiplexing optical network between a plurality of users connected to the network. The system utilizes a primary optical source generator that is either tunable, or capable of generating a plurality of wavebands of different frequencies equal to the sum of wavebands serving individual users of the network to facilitate a key exchange between the individual users of the network using summed wavebands, each of which serving an individual user.
