Claim Text:
1. A Kirchhoff-Law-Johnson-(like)-Noise (KLJN) system for secure key distribution, comprising: a wired network; and a plurality of hosts connected to each other on the wired network, wherein each host is connected to every other host by a continuous wired path capable of transmitting electrical current, wherein each host of the plurality of hosts comprises a first resistor and is configured to produce a first-resistor enhanced Johnson noise voltage when the first resistor is connected to a voltage source, wherein each host of the plurality of hosts further comprises a second resistor and is further configured to produce a second-resistor enhanced Johnson noise voltage when the second resistor is connected to a voltage source, wherein the resistance value of the first resistor of each host is identical to that of all other hosts of the plurality of hosts, wherein the resistance value of the second resistor of each host is the identical to that of all other hosts of the plurality of hosts, and wherein the plurality of hosts comprises at least three hosts.
