Abstract

A method for generating a secure one-time network for a new device includes receiving an instruction at an access point for generation of a one-time network. A wireless network adapter is configured by the access point when connected to the access point. The wireless network adapter is moved to the new device and the one-time network is activated by the access point. The new device uses the wireless network adapter to access the resources of the access point via the one-time network. Access to the one-time network via the wireless adapter is performed without exposing any network keys to the user of the new device.

First claim

1 . A method for generating a one-time network, the method comprising:
receiving a request at an access point for generation of the one-time network; configuring a wireless network adapter by the access point; installing the wireless network adapter on a device of the one-time network; initializing access to the one-time network for the device; accessing the one-time network by the device; and providing one-time network interaction on the device; wherein accessing the one-time network is performed without exposing any network key of the access point.

2 . The method of claim 1 , wherein the step of receiving a request comprises one of connecting the wireless network adapter to the access point, and selecting a service set identifier of the one-time network.

3 . The method of claim 1 , wherein the step of receiving an instruction comprises one of detecting a button activation on either the access point or the wireless network adapter.

4 . The method of claim 1 , wherein the step of configuring a wireless network adapter comprises writing one or more of a channel for operation of the one-time network, a service set identifier, a network key, and an operational restriction.

5 . The method of claim 4 , wherein the operational restriction comprises one or more of a limited time to connect the wireless network adapter to the device, a time duration of one-time network access, and a resource access restriction.

6 . The method of claim 1 , wherein the step of configuring a wireless network adapter is followed by activation of the one-time network.

7 . The method of claim 6 , wherein activation of the one-time network comprises not publishing the service set identifier.

8 . The method of claim 1 , wherein the step of installing the wireless network adapter on a device of the one-time network comprises disconnecting the wireless network adapter from the access point and connecting it to the device.

9 . The method of claim 1 , wherein the step of accessing the one-time network by the device comprises accessing resources available to the access point.

10 . An apparatus for generating a one-time network, the apparatus characterized by:
an input/output interface for receiving a request for generation of the one-time network; a processor, connected to memory that functions to configure a wireless network adapter connected to the apparatus; a one-time network interface to communicate with the wireless network adapter when connected to a device, the processor acting to activate the one-time network after configuring the wireless network adapter; wherein the wireless network adapter is configured by the processor to access the one-time network without exposing any network key of the apparatus.

11 . The apparatus of claim 10 , wherein the input/output interface comprises a connection for the wireless network adapter, the request resulting from connection of the wireless network adapter to the input/output interface.

12 . The apparatus of claim 10 , wherein the input/output interface comprises an interface for detection of button activation on either the apparatus or the wireless network adapter.

13 . The apparatus of claim 10 , wherein the processor acts to configure the wireless network adapter by writing one or more of a channel for operation of the one-time network, a service set identifier, a network key, and an operational restriction onto the wireless network adapter.

14 . The apparatus of claim 13 , wherein the operational restriction is one or more of a limited time to connect the network adapter to the device, a time duration of one-time network access, and a resource access restriction.

15 . The apparatus of claim 10 , wherein the processor activates the one-time network interface after configuring the wireless network adapter without publishing a name of the one-time network interface.
