Abstract

Particular embodiments of a gateway computing device may provide a provisioning service for access credentials for a restricted network. The gateway computing device may receive, from a client device, a request for the access credentials, wherein the request was sent over an open network using a restricted-packet-size protocol designed to limit power usage by devices sending messages using the protocol. The gateway computing device may segment data comprising the access credentials into a plurality of packets, wherein the plurality of packets conform to the restricted-packet-size protocol. Finally, the gateway computing device may send, over the open network to the client device, the segmented data using the restricted-packet-size protocol.

First claim

What is claimed is:

1. A method comprising:
by a gateway computing device, providing a provisioning service for access credentials;
by the gateway computing device, receiving, from a client device, a request for the access credentials, wherein the request was sent using a restricted-packet-size protocol;
by the gateway computing device, assessing the client device to determine whether the client device is authorized to establish a connection with a network, wherein the gateway computing device is configured to access the client device using information that was previously received and cached prior to the gateway computing device receiving any requests from client devices for access credentials;
in response to determining that the client device is associated with an authorized user, by the gateway computing device, segmenting data comprising the access credentials into a plurality of packets, wherein size of each of the plurality of packets conforms to a threshold size limit of the restricted-packet-size protocol, and wherein each of the plurality of packets comprises a header including sequencing information specifying an order in which the packet should be assembled with other packets at the client device of the user for re-constructing the data comprising the access credentials; and
by the gateway computing device, sending, to the client device, the plurality of packets comprising the access credentials using the restricted-packet-size protocol, wherein the data comprising the access credentials is re-assembled at the client device of the user using the sequencing information included in the packets.

2. The method of claim 1 , wherein the access credentials comprise authorization credentials to send messages using a different protocol than the restricted-packet-size protocol.

3. The method of claim 2 , wherein the restricted-packet-size protocol is designed to limit power usage by devices sending messages using the restricted-packet-size protocol.

4. The method of claim 3 , wherein the restricted-packet-size protocol is BLUETOOTH LOW ENERGY and the different protocol is WIFI.

5. The method of claim 4 , wherein the request specifies a universally unique identifier (UUID) for the provisioning service.

6. The method of claim 1 , wherein the client device can send messages to the gateway computing device using the restricted-packet-size protocol without first pairing with the gateway computing device.

7. The method of claim 1 , wherein each of the plurality of packets further comprises a payload, wherein the payloads for the packets comprise the segmented data.

8. A gateway computing device comprising one or more processors and a memory coupled to the processors comprising instructions executable by the processors, the processors being operable when executing the instructions to:
provide a provisioning service for access credentials;
receive, from a client device, a request for the access credentials, wherein the request was sent using a restricted-packet-size protocol;
assess the client device to determine whether the client device is authorized to establish a connection with a network, wherein the gateway computing device is configured to access the client device using information that was previously received and cached prior to the gateway computing device receiving any requests from client devices for access credentials;
in response to a determination that the client device is associated with an authorized user, segment data comprising the access credentials into a plurality of packets, wherein size of each of the plurality of packets conforms to a threshold size limit of the restricted-packet-size protocol, and wherein each of the plurality of packets comprises a header including sequencing information specifying an order in which the packet should be assembled with other packets at the client of the user for re-constructing the data comprising the access credentials; and
send, to the client device, the plurality of packets comprising the access credentials using the restricted-packet-size protocol, wherein the data comprising the access credentials is re-assembled at the client device of the user using the sequencing information included in the packets.

9. The gateway computing device of claim 8 , wherein the access credentials comprise authorization credentials to send messages using a different protocol than the restricted-packet-size protocol.

10. The gateway computing device of claim 9 , wherein the restricted-packet-size protocol is designed to limit power usage by devices sending messages using the restricted-packet-size protocol.

11. The gateway computing device of claim 10 , wherein the restricted-packet-size protocol is BLUETOOTH LOW ENERGY and the different protocol is WIFI.

12. The gateway computing device of claim 11 , wherein the request specifies a universally unique identifier (UUID) for the provisioning service.

13. The gateway computing device of claim 8 , wherein the client device can send messages to the gateway computing device using the restricted-packet-size protocol without first pairing with the gateway computing device.

14. The gateway computing device of claim 8 , wherein each of the plurality of packets further comprises a payload, wherein the payloads for the packets comprise the segmented data.

15. One or more computer-readable non-transitory storage media embodying software that is operable when executed by one or more processors of a gateway computing device to:
provide a provisioning service for access credentials;
receive, from a client device, a request for the access credentials, wherein the request was sent using a restricted-packet-size protocol;
assess the client device to determine whether the client device is authorized to establish a connection with a network, wherein the gateway computing device is configured to access the client device using information that was previously received and cached prior to the gateway computing device receiving any requests from client devices for access credentials;
in response to a determination that the client device is associated with an authorized user, segment data comprising the access credentials into a plurality of packets, wherein size of each of the plurality of packets conforms to a threshold size limit of the restricted-packet-size protocol, and wherein each of the plurality of packets comprises a header including sequencing information specifying an order in which the packet should be assembled with other packets at the client device of the user for re-constructing the data comprising the access credentials; and
send, to the client device, the plurality of packets comprising the access credentials using the restricted-packet-size protocol, wherein the data comprising the access credentials is re-assembled at the client device of the user using the sequencing information included in the packets.

16. The one or more computer-readable non-transitory storage media of claim 15 , wherein the access credentials comprise authorization credentials to send messages using a different protocol than the restricted-packet-size protocol.

17. The one or more computer-readable non-transitory storage media of claim 16 , wherein the restricted-packet-size protocol is designed to limit power usage by devices sending messages using the restricted-packet-size protocol.

18. The one or more computer-readable non-transitory storage media of claim 17 , wherein the restricted-packet-size protocol is BLUETOOTH LOW ENERGY and the different protocol is WIFI.

19. The one or mo
