determining the validity of the request according to a verification code carried by the request; sending a response to the station; receiving a security message from the station; retrieving a security key carried by the security message; and executing network provisioning according to the security key. ## Claims ### Claim 1 A method for auto provisioning for a communication device, comprising the steps of: receiving a request from a station; determining the validity of the request according to a verification code carried by the request; sending a response to the station; receiving a security message from the station; retrieving a security key carried by the security message; and executing network provisioning according to the security key, wherein the security message is a Wi-Fi protected setup (WPS) extensible authentication protocol (EAP) message, and the security key is an encrypted PIN code of the station for avoiding PIN code manual inputting. ### Claim 2 (depends on 1) The method of claim 1, further comprising a step of: determining whether to accept the request according to the signal strength of the request. ### Claim 3 (depends on 1) The method of claim 1, wherein the signal strength of the request is indicated by a received signal strength indicator (RSSI). ### Claim 4 (depends on 1) The method of claim 1, wherein the verification code is included in a vendor data part of the request. ### Claim 5 (depends on 1) The method of claim 1, wherein a reason data of acceptance and rejection is carried by the response. ### Claim 6 (depends on 4) The method of claim 4, wherein the reason data, which is 1 bit by length, is included in a vendor data part of the response. ### Claim 7 (depends on 1) The method of claim 1, wherein the security key is included in a vendor data part of the security message. ### Claim 8 (depends on 1) The method of claim 1, wherein the communication device is an access point. ### Claim 9 (depends on 1) The method of claim 1, wherein the communication device is a station serving as an independent basic service set (IBSS) creator in an ad-hoc mode. ### Claim 10 (depends on 9) The method of claim 9, further comprising the steps of: setting up a timer; and leaving the ad-hoc mode if the timer is expired. ### Claim 11 (depends on 1) The method of claim 1, wherein the communication device is a station in an ad-hoc mode. ### Claim 12 (depends on 11) The method of claim 11, further comprising the steps of: leaving the ad-hoc mode if no other station in ad hoc mode is found. ### Claim 13 A method for auto provisioning for a station, comprising the steps of: searching for a communication device by sending a request, wherein the request carries a verification code; receiving a response from a communication device; and sending a security message to the communication device, wherein the security message carries a security key, wherein the security message is a Wi-Fi protected setup (WPS) extensible authentication protocol (EAP) message, and the security key is an encrypted PIN code of the station for avoiding PIN code manual inputting. ### Claim 14 (depends on 13) The method of claim 13, wherein the communication device is an access point. ### Claim 15 (depends on 14) The method of claim 14, further comprising a step of: entering an ad-hoc mode if no access point is found. ### Claim 16 (depends on 13) The method of claim 13, wherein the station is in an ad-hoc mode, and the communication device is another station in an ad-hoc mode. ### Claim 17 (depends on 16) The method of claim 16, further comprising a step of: leaving the ad-hoc mode if no other station in ad hoc mode is found. ### Claim 18 (depends on 13) The method of claim 13, wherein the verification code, which is 16 bytes by length, is included in a vendor data part of the request. ### Claim 19 (depends on 13) The method of claim 13, wherein a reason data of acceptance and rejection is carried by the response. ### Claim 20 (depends on 19) The method of claim 19, wherein the reason data is included in a vendor data part of the response. ### Claim 21 (depends on 13) The method of claim 13, wherein the security key is included in a vendor data part of the security message.
