Abstract
Out-of-band quantum key distribution using cellular SMS can include receiving, from a user device, a client identifier that identifies the user device and a first key identifier that identifies a first key having a first key value that is a first quantumly generated random bit string. A second key that includes a second key value can be requested and received from the key service, the second key value including a second quantumly generated random bit string. The second key value can be provided to a short message service center for delivery to the user device. An operation can be performed on the first key value and the second key value to obtain a copy of a pre-shared key, which can be used when exchanging encrypted communications with the user device.
