US Patent 11218300 Systems and methods for post-quantum cryptography communications channels

Systems, apparatuses, methods, and computer program products are disclosed for PQC. An example method includes transmitting a first portion of an electronic communication to a client device over a non-PQC communications channel. The example method further includes transmitting a second portion of the electronic communication to a PQC add-on device over a PQC communications channel, wherein the PQC add-on device is communicatively coupled to the client device. In some instances, the first portion of the electronic communication may comprise overhead data, and the second portion of the electronic communication may comprise payload data.
