US Patent 12088704 Systems and methods for quantum entangled random key exchange

Systems, apparatuses, methods, and computer program products are disclosed for secure key exchange. An example method includes receiving, by communications hardware of a first device, a message from a second device. The example method also includes encrypting, by data protection circuitry of the first device, the message using a first key shared between the first device and a third device, wherein the first key is derived based at least on a first random bit set known to the first device and the third device. The example method also includes causing transmission, by the communications hardware of the first device, of the encrypted message to the third device.
