This paper presents an ultra-secure router-to-router key exchange system. The key exchange process can be initiated by either router at will and can be carried out as often as required. We compare the efficacy of the proposed approach with contemporary quantum key distribution (QKD) systems and show that quantum-level security is attainable without resorting to single photon generators and other attendant instrumentation associated with QKD. Furthermore, the proposed system addresses the extremely limited geographical reach of commercially available QKD systems and other environmental restrictions they must operate in. The proposed system carries out all processing in electronics and is not vulnerable to the man in the middle attack. The medium of transfer can, of course, be optical fibers as is common in telecommunication.
