PROVISIONING A WIRELESS DEVICE FOR SECURE COMMUNICATION USING AN ACCESS POINT DESIGNED WITH PUSH-BUTTON MODE OF WPS (WI-FI PROTECTED SETUP)
A wireless device is provisioned according to WPS (WiFi Protected Setup) push button mode. The wireless device receives an electronic signal from a provisioning agent external to the wireless device, the electronic signal indicating to the wireless device that the wireless device is to start WPS provisioning procedures. A user presses a push button on an AP to which the wireless device is to be connected. On receipt of the electronic signal, the wireless device enrolls in a wireless network, of which the AP is a part, by communicating with the access point in accordance with push button mode of WPS. The technique enables a wireless device to be provisioned without a user requiring to press any button on the wireless device.
1 . A method of provisioning a wireless device for communication with an access point, said method comprising:
receiving an electronic signal from an agent; and
responsive to receipt of said electronic signal, enrolling in a wireless network by communicating with an access point in accordance with a push-button mode of WPS standard, wherein said wireless network comprises said access point,
wherein said agent is implemented external to both of said access point and said access point.
2 . The method of claim 1 , wherein said enrolling comprises:
receiving a set of parameters from said access point, wherein said set of parameters are required to securely communicate with said access point; and
configuring said wireless station with said set of parameters to enable said wireless device to join a basic service set (BSS) of which said access point is a member.
3 . The method of claim 2 , wherein said set of parameters comprise a SSID of said access point and a passphrase used in accordance with a security protocol.
4 . The method of claim 2 , further comprising:
broadcasting a request for being provisioned, wherein said electronic signal is received responsive to said broadcasting.
5 . The method of claim 4 , wherein said request is broadcast in the form of a beacon message.
6 . The method of claim 2 , further comprising communicating with other wireless stations of said wireless network upon completion of said enrolling.
7 . The method of claim 1 , wherein said electronic signal comprises a probe request message, wherein an SSID field of said probe request message contains a command to initiate provisioning according to said push-button mode of WPS standard.
8 . The method of claim 2 , further comprising:
sending a confirmation message from said wireless device to said provisioning agent, said confirmation message specifying whether said enrolling was successful or not.
9 . A non-transitory machine readable storage medium storing one or more sequences of instructions for provisioning a wireless device for communication with an access point, wherein execution of said one or more sequences of instructions by one or more processors contained in said wireless device enables said wireless device to perform the actions of:
receiving an electronic signal from an agent; and
responsive to receipt of said electronic signal, enrolling in a wireless network by communicating with an access point in accordance with a push-button mode of WPS standard, wherein said wireless network comprises said access point,
wherein said agent is implemented external to both of said access point and said access point.
10 . The non-transitory machine readable storage medium of claim 9 , wherein said enrolling comprises:
receiving a set of parameters from said access point, wherein said set of parameters are required to securely communicate with said access point; and
configuring said wireless station with said set of parameters.
wherein said set of parameters comprise a SSID of said access point and a passphrase used in accordance with a security protocol.
11 . The non-transitory machine readable storage medium of claim 9 , further comprising instructions to enable said wireless device to perform the action of:
broadcasting a request for being provisioned, wherein said electronic signal is received responsive to said broadcasting.
12 . The non-transitory machine readable storage medium of claim 11 , wherein said request is broadcast in the form of a beacon message.
13 . The non-transitory machine readable storage medium of claim 10 , further comprising instructions to cause said wireless device to perform the action of communicating with other wireless stations of said wireless network upon completion of said enrolling.
14 . The non-transitory machine readable storage medium of claim 9 , wherein said electronic signal comprises a probe request message, wherein an SSID field of said probe request message contains a command to initiate provisioning according to said push-button mode of WPS standard.
15 . A system comprising:
a provisioning agent to generate an electronic signal to command a wireless device to initiate push button mode of WPS; and
a wireless device designed to:
receive said electronic signal from said provisioning agent; and
enroll, in response to receipt of said electronic signal, in a wireless network by communicating with an access point in accordance with a push-button mode of WPS standard, wherein said wireless network comprises said access point.
16 . The system of claim 15 , wherein during said enrolling, said wireless device receives a set of parameters from said access point, wherein said set of parameters are required to securely communicate with said access point.
17 . The system of claim 16 , wherein said set of parameters comprise an SSID of said access point and a passphrase used in accordance with a security protocol.
18 . The system of claim 17 , wherein said wireless device broadcasts a request for being provisioned, wherein said provisioning agent generates said electronic signal in response to receipt of said request.
19 . The system of claim 16 , wherein said request is broadcast in the form of a beacon message, wherein said electronic signal comprises a probe request message, wherein an SSID field of said probe request message contains a command to initiate provisioning according to said push-button mode of WPS standard.
20 . The system of claim 16 , wherein said wireless device sends a confirmation message to said provisioning agent, said confirmation message specifying whether said enrolling was successful or not.
