Abstract

A computer device may include a memory storing instructions and processor configured to execute the instructions to receive a request for quantum random numbers from a client device. The processor may be further configured to establish a secure communication channel with the client device; obtain a stream of quantum random numbers from a quantum random number generator appliance; and provide a set of quantum random numbers from the obtained stream of quantum random numbers to the client device via the established secure communication channel.

Claims (53)

1. A method comprising:

receiving, by a computer device, a request for quantum random numbers from a client device;

determining, by the computer device, a quantity of quantum random numbers requested by the client device;

establishing, by the computer device, a secure communication channel with the client device;

obtaining, by the computer device, a stream of quantum random numbers from a quantum random number generator;

providing, by the computer device, the determined quantity of quantum random numbers from the obtained stream of quantum random numbers to the client device via the established secure communication channel; and

removing, by the computer device, the determined quantity of quantum random numbers from the stream of quantum random numbers, after providing the determined quantity of quantum random numbers to the client device via the established secure communication channel.

2. The method of claim 1 , wherein the secure communication channel includes a Software Defined Perimeter (SDP) channel.

3. The method of claim 1 , wherein the stream of quantum random numbers includes a real time stream of quantum random numbers.

4. The method of claim 1 , wherein the stream of quantum random numbers includes quantum random numbers retrieved from a data store.

5. The method of claim 1 , further comprising: generating a public key certificate using quantum numbers from the stream of quantum random numbers.

6. The method of claim 5 , further comprising:

generating a secure communication tunnel to another device using the generated public key certificate.

7. The method of claim 1 , further comprising:

encrypting one or more quantum random numbers, from the stream of quantum random numbers, into a public key; and

providing the public key to the client device.

8. The method of claim 1 , further comprising:

providing a set of quantum random numbers, from the stream of quantum random numbers, to another device via a quantum key distribution (QKD) link.

9. The method of claim 1 , further comprising:

hashing a set of quantum random numbers, from the stream of quantum random numbers, with random numbers from a local source to generate a random number stream.

10. A computer device comprising:

a memory storing instructions; and

a processor configured to execute the instructions to:

receive a request for quantum random numbers from a client device;

determine a quantity of quantum random numbers requested by the client device;

establish a secure communication channel with the client device;

obtain a stream of quantum random numbers from a quantum random number generator;

provide the determined quantity of quantum random numbers from the obtained stream of quantum random numbers to the client device via the established secure communication channel; and

remove the determined quantity of quantum random numbers from the stream of quantum random numbers, after providing the determined quantity of quantum random numbers to the client device via the established secure communication channel.

11. The computer device of claim 10 , wherein the secure communication channel includes a Software Defined Perimeter (SDP) channel.

12. The computer device of claim 10 , wherein the processor is further configured to: generate a public key certificate using quantum numbers from the stream of quantum random numbers.

13. The computer device of claim 12 , wherein the processor is further configured to:

generate a secure communication tunnel to another device using the generated public key certificate.

14. The computer device of claim 10 , wherein the processor is further configured to:

provide a set of quantum random numbers, from the stream of quantum random numbers, to another device via a quantum key distribution (QKD) link.

15. The computer device of claim 10 , wherein the processor is further configured to:

hash a set of quantum random numbers, from the stream of quantum random numbers, with random numbers from a local source to generate a random number stream.

16. A system comprising:

a first computer device; and

a second computer device; wherein

the first computer device is configured to:

establish a secure communication channel with the second computer device;

obtain a stream of quantum random numbers from a quantum random number generator;

provide a particular quantity of quantum random numbers from the obtained stream of quantum random numbers to the second computer device via the established secure communication channel; and

remove the provided particular quantity of quantum random numbers from the stream of quantum random numbers, after providing the particular quantity of quantum random numbers to the second computer device via the established secure communication channel; and wherein the second computer device is configured to:

generate a public key certificate using quantum numbers from the provided particular quantity of quantum random numbers; and

generate a secure communication tunnel to another device using the generated public key certificate.

17. The system of claim 16 , wherein the secure communication channel includes a Software Defined Perimeter (SDP) channel.

18. The system of claim 16 , wherein the first computer device is configured to provide the particular quantity of quantum random numbers, from the stream of quantum random numbers, to another device via a quantum key distribution (QKD) link.

19. The system of claim 16 , wherein the first computer device is further configured to:

hash the particular quantity of quantum random numbers, from the stream of quantum random numbers, with random numbers from a local source to generate a random number stream.

20. The system of claim 16 , wherein the first computer device is further configured to: encrypt one or more quantum random numbers, from the stream of quantum random numbers, into a public key; and

provide the public key to another device.
