Description
Technical field
The present invention relates to communication means and the equipment of WLAN (wireless local area network).
Background technology
Due to the convenience of WLAN, increasing equipment (as mobile phone, iPad, iTouth, net book, notebook, network player, the network storage equipment etc.) is supported WLAN(WLAN (wireless local area network)) function.IEEE(Institute of Electrical and Electric Engineers) standard of 802.11 series is WLAN standard that IEEE organizes to set up.The standard of 802.11 series, comprises 802.11a, 802.11b, 802.11c, 802.11d, 802.11e, 802.11f, 802.11g, 802.11h, 802.11i and 802.11n etc. at present.Wherein, ripe 802.11g transmission rate has reached 54 megabit per seconds at present, and 802.11n has reached 300 ~ 600 megabit per seconds especially.
The frequent meeting of WLAN (wireless local area network) and Wi-Fi lump together.It is the abbreviation of Wireless Fidelity (wireless fidelity) that Wi-Fi starts most, at the category of WLAN (wireless local area network), refers to " wireless compatibility authentication ".
In 802.11 standards, following two kinds of equipment or entity have been defined.Mobile radio station (STA), any equipment that contains the wireless medium interface that meets IEEE 802.11 media access controls (MAC) and physical layer defined; Access point (AP), has the function of mobile radio station (STA), and provides any entity of access by wireless medium for associated STA.In standard, also define MAC and physical layer, for example, in 802.11 standards of 2007 editions, in " the 5th chapter universal description (General description) ", described the common process of setting up 802.11 associations; Mac frame form, the form of every kind of frame type, the management of frame (body) structure, the contents such as using method of frame have been described in " the 7th chapter frame format (Frame formats) ".
Wi-Fi network, has AP and STA jointly to form conventionally, and typical Wi-Fi network constituted mode, is an AP and a plurality of STA.On this basis, can also consist of a plurality of AP and a plurality of STA, these AP can, by the mode of bridge joint, work all AP and STA under same wireless network.
Seeing Fig. 1, is that 802.11 agreement defineds a kind of sets up associated process schematic diagram.STA sends probe request to AP; AP returns to probe response, has wherein carried safe relevant parameter; AP sends open system authentication request to STA; AP returns to open system authentication response; STA sends associated request, has wherein carried safe relevant parameter; AP returns to associated response.So far, STA has completed the association of AP therewith.
The association process of Fig. 1 has been used open system authentication, is equivalent to without authentication.
802.11 also provide shared key authentication (shared key authentication) mode.Shared key authentication method, be of will share or a group key by being independent of other modes of 802.11 networks, be distributed to each STA and AP.At STA, connect while entering AP, AP sends the random password (challenge) generating to STA, and STA returns to AP with the key having obtained after to this password encryption, if AP successful decryption is thought this STA access of having the right.Above-mentioned ciphering process may use wired equivalent privacy (WEP) algorithm.
WEP is also for data encryption.WEP function application data Partial encryption, replaces the plaintext in former frame to send with ciphertext, and WEP position is set in the frame control field of MAC head, informs that receiving node transmits data and encrypts, and receiving node is received after ciphertext frame, by identical mechanism, decrypted original text.
In 802.11i, further introduced wireless protection access (WPA, i.e. wireless protected access) method, WPA is the subset of wireless protection access version 2 (WPA2, wireless protected access version 2) agreement.In data encryption, WPA has been used Temporal Key Integrirty Protocol (TKIP, i.e. temporal key integrity protocol).WPA2 has adopted the algorithm based on advanced encryption standard (AES, i.e. advanced encryption standard).
802.11i has proposed the concept of robust security network (RSN, i.e. robust security network).RSN operation mainly comprises four-stage, finds AP, 802.1x authentication, key management and safety data transmission.In above-mentioned authentication phase, need to use pairwise master key (PMK, be pairwise master key), the acquisition of PMK has two kinds of modes, the one, need certificate server, as remote customer dialing authentication server (RADIUS), and the negotiation of STA produces, another one mode is exactly wildcard (PSK, i.e. preshared key).
Fig. 2 is the interchangeable frame form schematic diagram of agreement defined, 802.11 agreement regulations, the basic structure of mac frame, comprises a) MAC head, contains frame control, duration, address 1, address 2, address 3, sequence control information, address 4, service quality control information; B) frame of variable-length, contains the corresponding distinctive information of frame type and subtype; C) Frame Check Sequence number (FCS), the cyclic redundancy check (CRC) that contains 32 bit long.
Above-mentioned frame type and sub-type field are to be comprised in the frame control information of MAC head.Wherein, frame type field 2 bit long, sub-type field 4 bit long.There are three kinds of frame types, management, control and data, respectively corresponding binary bits 00 to 10.Each type is divided into again a plurality of subtype.
The subtype of management type comprises associated request, associated response, reassociation requests, re-association response, probe request, probe response, respectively corresponding binary bits 000 to 0101; Subtypes such as also comprising the indication of beacon, declaration business, go association, authenticate, go authentication, be movable, respectively corresponding binary bits 1000 to 1101; And 0110 to 0111 and 1110 to 1111, for 802.11 agreements of 2007 editions, retain.
Control also corresponding multiple subtype of type, wherein 0000 to 0111 bit retains.
The bit of data type is 1101 to be to retain.
In addition, frame type bit 11 retains, and the corresponding subtype of 11 type from 0000 to 1111 so, all retains.
802.11 agreements have further been stipulated the using method of frame.At length stipulated above-mentioned each seed category frame receipts and send out, under various conditions, whether STA and AP need to support separately.For example, subtype is the frame of associated request, and under the scene of non-service quality (QoS) requirement and competing cycle, STA need to support the transmission of this frame, and AP need to support the reception of this frame; Under similarity condition, for subtype, be associated corresponding frame, STA need to support to receive, and AP needs to support to send; Under kindred circumstances, the frame that subtype is data, STA and AP all should support to receive and send.Can imagine, if an equipment has been supported the complete or collected works of the function of STA and AP, this equipment can be used as STA, also can be used as AP.
Each AP has a service configuration identifier (SSID, i.e. service set identifier) to identify its oneself, and SSID is broadcasted in the frame of beacon frame, and at other frames, for example, in probe request frame, is cited.SSID is equivalent to the title of AP.
Each AP also has a basic service that identifier (BSSID, i.e. basic service set identifier) is set, and BSSID is equivalent to the MAC Address of AP, conventionally appears at the somewhere in address 1 to the address 4 of MAC head.
802.11 support broadcast (Broadcast) and multicast (Multicast) mode.In fact, broadcast can be considered as a special case of multicast.Broadcast address just refers to unique multicast address of all STA in fact; And multicast group address, corresponding one group of STA logically.
As mentioned above, as seen at AP equipment, multiple auth type can be set, cryptographic algorithm, and the key prestoring, also comprise the parameter configuration of other key managements, such as key updating cycle etc.These configuration informations, some parameter, AP can broadcast in network, and some parameter is to distribute by the channel outside 802.11 by the mode outside band.These all or part of configuration informations, need to configure respectively at AP and STA, for example, and wildcard.
For AP equipment, conventionally need at present the parameter arranging to comprise, SSID, safety arranges.Wherein safety setting comprises:
1) open wireless safety not, is equivalent to open system;
2) WPA-PSK/WPA2-PSK mode, the wildcard mode of WPA/WPA2, needs further to configure cryptographic algorithm as AES, PSK key, group key management cycle;
3) WPA/WPA2 mode, the mode of consulting acquisition PMK, needs further configuration, cryptographic algorithm, radius server IP, radius port, radius password, group key management cycle;
4) WEP mode, needs further configuring cipher key form, one or more key; Owing to relating to a plurality of keys, so each key corresponding cipher key index number also.
Under above-mentioned all different authentication types, need the password, the key that use, as the shared key in WEP, WPA-PSK, WPA2-PSK, the radius password in WPA/WPA2 etc., are generally called " access pin ".
Auth type, comprises open system, shared key and automatically selects.Automatically selecting is that auto negotiation is a kind of in verification process.And shared key mode can be further divided into the types such as WEP, WPA-PSK, WPA2-PSK.
Above-mentionedly allly need to be configured configuration information all or part of that just can make STA successfully be linked into AP and then be linked into network in STA side, as access pin, SSID, auth type, port, period of key etc., be commonly referred to as " access configuration information ".
At this, with access, as access a Wi-Fi equipment, or access Wi-Fi network, the verification process of describing association process and also may needing.Different authentication modes, its authentication phase may be accompanied by the association process described in agreement; Also may be after association process described in agreement, to carry out again authentication.
Although a STA is not successfully linked into an AP by authentication, still can receive the information that this AP sends, beacon message for example, and receive the information that other STA send.
That Wi-Fi wireless network has is removable, without the powerful advantages of wiring, but simultaneously owing to there is no the restriction of physics cable, there is serious safety issue in Wi-Fi wireless network, so Wi-Fi standard provides the configuration that multiple safety is relevant.This has caused the layoutprocedure of equipment access wireless network for common user, and very complex is difficult to while going wrong solve especially.For common domestic consumer and the webmaster of company, equipment of every interpolation all will repeat whole layoutprocedure to Wi-Fi network, and this has reduced networking efficiency, has also reduced the efficiency of the whole network Reconfigurations when access configuration is modified.In addition, although some equipment is supported Wi-Fi, do not have good input-output equipment, for example, do not have keyboard or keyboard operation not convenient, or there is no screen etc., the layoutprocedure user of these equipment access Wi-Fi network is experienced and can be reduced.

Embodiment
With reference to the accompanying drawings the present invention is described more fully, exemplary embodiment of the present invention is wherein described.Exemplary embodiment of the present invention and explanation thereof are used for explaining the present invention, but do not form inappropriate limitation of the present invention.
To the description only actually of at least one exemplary embodiment, be illustrative below, never as any restriction to the present invention and application or use.
The object of the present invention is to provide a kind of processing method of Wi-Fi wireless network access configuration information, the workload that while reducing multiple devices access of radio network, repeated configuration causes; And be input/output unit imperfection, the equipment that does not does not even input or output device provides collocation method more easily.Object of the present invention is achieved through the following technical solutions.
In the present invention, described Wi-Fi equipment, comprises AP and/or STA.
Embodiment mono-
Embodiment mono-has disclosed a kind of processing method that accesses configuration information of the present invention.Seeing Fig. 3, is the processing method schematic diagram of the access configuration information of the present embodiment.
Step 10: mobile radio station, STAx, accesses AP, i.e. AP1.Now, STAx has obtained the presently used effective configuration information of AP1.
Before successfully accessing first, conventionally need user that STAx is manually set, select the SSID of described AP1; If this AP1 is not set to open system, need user further to input access pin.At follow-up access procedure, because STAx had successfully accessed AP1, the corresponding configuration information of AP1 is saved, and STAx can directly attempt with the configuration information access network of having preserved.If AP1 has upgraded the configurations such as SSID, access pin or auth type, may cause STAx cannot continue to be successfully linked into this network, need user that access configuration information is manually set again.
Suppose that STAx was also once linked into AP2 before, STAx has also obtained the presently used effective configuration information of AP2 network.
Step 20:STAx is used all or part of of the access configuration information obtain, forms access configuration information frame, in wireless network, sends.
The configuration information that STAx sends, should comprise the configuration information that AP1 is used, optional, further comprises the configuration information that AP2 is used.
As for whether sending the configuration information that AP2 is used, can whether can be scanned and decide by STAx according to AP2.If STAx can scan the existence of AP2, for example received the beacon frame of AP2, STAx comprises the configuration information into AP2 in access configuration information frame so; Otherwise, do not comprise the configuration information into AP2.Further, STAx can taste and try into AP2, and whether the AP2 access configuration information obtaining before checking is effective, if can access AP2, information is effective; Otherwise be invalid.If the access configuration information of AP2 is invalid, in the access configuration information frame that STAx sends, do not comprise the access configuration information of AP2.If there is more AP, can be by that analogy.
STAx can send access configuration information frame by cycle T, and it is unit that cycle T be take the time interval (interval) or the chronomere (time unit) of Wi-Fi agreement defined.The described time interval comprises the beacon time interval (beacon interval), time of intercept interval (listen interval) or service time interval (service interval).For example, T is the time of intercept interval of 2 times.
Step 30: follow-up other need the STA of access network, as STAy, can scan the current AP that can detect.Described y is not equal to x, i.e. any other one or more STA that are different from STAx.STAy supposes that STAy also selects to access AP1, if can first be used the existing configuration information existing to attempt access AP1.If STAy does not have the configuration information of pre-stored AP1, or it is unsuccessful to use configuration information to attempt access, and AP1 is not set to open system yet, and STAy attempts receiving access configuration information frame.If STAy receives the access configuration information frame that STAx sends, parse the access configuration information that AP1 is used, and use these information access AP1.STAy also may scan the existence of AP2, and receives the access configuration information of the AP2 that STAx sends, and uses the configuration information access AP2 receiving.
Certainly, STAy attempt to receive this process of access configuration information frame, and before also can occurring in and using the process that the configuration information of local storage attempts, or both are parallel occurs.These two processes are independent generations, or the exploitativeness of the present embodiment successively occurs not affect.
Before STAy is being linked into AP1 or AP2, if effective access information is not stored in this locality, continue to receive access configuration information frame, until receive effective access configuration information, and for access.
After STAy is linked into AP, also can continue to receive access configuration information frame.If do not receive for a long time access configuration information frame, for example, the time of the T of several times, STAy constructs access configuration information frame with current access configuration information, and by cycle T, sends access configuration information frame.
In addition, the operating procedure 30 of STAy shown in Fig. 3, just for the logical order to outgoing event generation, so that understand.In fact, the operation of STAy and step 10 and step 20 are independently in sequential.Suppose the local not effective access configuration information of storage of STAy, STAy can continue to receive access configuration information frame, until receive STAx, sends configuration information, and till being linked into AP1.
Embodiment bis-
Seeing Fig. 4, is the schematic diagram of the processing method of the access configuration information of the present embodiment.
The present embodiment two is on the basis of embodiment mono-, before STA sends access configuration information frame, further judges whether to need to send the method for access configuration information frame.
Step 11:STAx receives access configuration information frame.
Whether step 12:STAx judgement, within first scheduled time, receives access configuration information frame, if so, turns back to step 11, otherwise performs step 13.
Described first scheduled time, preferred value is that access configuration information frame sends the more than 2 times or 2 times of cycle T.
Step 13:STAx generates a random delay, Dt, and in random delay, continue to receive access configuration information frame.
Whether step 14:STAx judgement, in random delay, has received access configuration information frame, if so, returns to step 11, otherwise performs step 20.
Step 20:STAx is used all or part of of the access configuration information obtain, forms access configuration information frame, in wireless network, sends.
In step 13, being provided with the object of a random delay, is in order to realize the competition mechanism between a plurality of STA.For example, in the wireless network at AP1 place, before STAx, once had a STAz continue sending access configuration information frame, in order to receive and transmission avoids conflict, it is not send access configuration information frame that other STA preferably operate.Suppose that the reasons such as power-off of STAz have left this Wi-Fi network, at this moment, may have a plurality of STA intercepting access configuration information frame, and continue 2 or 2 above access configuration information frames and send the cycles, do not receive access configuration information frame.These a plurality of STA may send access configuration information frame simultaneously, form and disturb each other.For fear of such conflict, each STA, before this continues to send access configuration information frame, is at war with, in this locality, generate a random delay, if in random delay, still do not receive access configuration information frame, this STA starts to send access configuration information frame.Like this, if a plurality of STA send access configuration information frame in competition, the large STA of local time delay producing, the little STA of local random delay that can first receive generation sends to access configuration information frame, the former will no longer send access configuration information frame like this, avoid conflict.STA can, before each transmission access configuration information frame, introduce above-mentioned competition mechanism; Once also can compete successfully, send out access configuration information frame, just send periodically constantly.
Preferred Dt generation method, is to generate to be less than the random delay of cycle T, and is set to Dt.
It should be noted that, the processing method of the access configuration information described in the present embodiment, transmission and/or the reception of access configuration information, its method of reseptance is can be self-existent, can exist individually by the present invention and realize the Wi-Fi equipment that receives access configuration information.
For example, all Wi-Fi mobile phones of realizing by the present invention, all support sending and receiving access configuration information frame; All Wi-Fi TVs of realizing by the present invention, Wi-Fi air-conditioning etc., all only support to receive access configuration information frame.Therefore because mobile phone has good input-output equipment, be easy to be configured and be linked into Wi-Fi network.And other Wi-Fi household electrical appliances, Wi-Fi TV for example, owing to there is no keyboard, operation can only use a teleswitch, the reception of access configuration information frame can be only realized, once receive the access configuration information that Wi-Fi mobile phone sends, Wi-Fi network can be automatically linked into.
Embodiment tri-
The present embodiment three, on embodiment mono-or two basis, has further disclosed the building method of access configuration information frame.
In order to allow recipient's STA can identify access configuration information frame, structure access configuration information frame can use the field configuration mode that Wi-Fi agreement retains.
For example, frame type bit is set to " 11 "; Or frame type bit is set to management, i.e. " 00 ", and subtype is got a value among " 0110 " to " 0111 " or " 1110 " to " 1111 "; Or frame type bit is set to control, i.e. " 01 ", and subtype is got a value among " 0000 " to " 0111 "; Or frame type bit is set to data, i.e. " 10 ", and subtype is set to " 1101 ".
In fact, the field value of any reservation in Wi-Fi agreement, or the configuration mode that cannot resolve of agreement, can be used for identifying the frame that such configuration mode occurs, is access configuration information frame.
For example, duration/identification field, length is 16 bits, and having a plurality of bit values is retention, and for example, front 14 bits are 0, and rear 2 bits are 1 to be retention., can use this configuration identifier access configuration information frame.
Access configuration information frame can be used above-mentioned multiple identification method to identify simultaneously, for example, used the retention of type, has also used the retention of duration/identification field.This be for fear of follow-up 802.11 agreements that derive, taken before the retention of agreement regulation, and cause the parsing ambiguity of the frame that receives.
The form of presentation that accesses configuration information in access configuration information frame, can adopt the frame structure design mode of any Wi-Fi of meeting agreement, as long as can resolve according to the STA of way of the present invention.
For example, adopt following mode that the frame of access configuration information frame is set:
A) access configuration information number;
B) access configuration information, further comprises:
B1）SSID；
B2）BSSID；
B3) auth type: span comprises open system, WPE, WPA-PSK/WPA2-PSK, WPA/WPA2;
B4) access pin; Or a group of access password and call number corresponding to each password;
B5) cryptographic algorithm.
B) number that access configuration information occurs, with A) access in a configuration information digital section, the number configuring equates.
Embodiment tetra-
Embodiment tetra-is on the basis of embodiment mono-to embodiment tri-, and the method to the encryption of access configuration information is further provided.
Access configuring information processing method of the present invention by these important informations such as access pins, sends in Wi-Fi network, so that the STA receiving can be linked into Wi-Fi network smoothly.But in order to guarantee fail safe, these access pins in the prior art, are not send in Wi-Fi network internal, but distribute by the channel outside Wi-Fi.Therefore, method of the present invention has reduced the fail safe of existing network.Any equipment that may resolve access configuration information frame of the present invention all may obtain the configuration of access Wi-Fi network.
In order to safeguard the fail safe of Wi-Fi network, can be encrypted send to access configuration information.According to different security requiremenies, can there is different cipher modes.
Cipher mode 1: if just wish can identify by the Wi-Fi equipment of the inventive method the frame of access configuration information, every other Wi-Fi equipment can not be identified, so only need realize identical encryption method on by Wi-Fi equipment of the present invention all, avoid the important informations such as access pin to be sent to Wi-Fi network by mode expressly, and without distribute again the Crypted password of access configuration information by other channels outside Wi-Fi.For example, can stab the bit information of (timestamp) field service time, access configuration information is carried out to the mode of XOR and encrypt.Or all Wi-Fi equipment of realizing by the present invention, has all stored identical a pair of PKI and private key, and all access configuration information transmit legs, are all used private key to be encrypted; And all access configuration information recipients use corresponding PKI to be decrypted.
Cipher mode 2: if wish to control the Wi-Fi equipment by the inventive method, make it freely not carry out correct parsing to access configuration information frame, need the configuration of cipher mode outside Wi-Fi channel or Crypted password etc.This point, can with the security configuration of Wi-Fi network on similarly.Difference is, all relevant Wi-Fi equipment only need once access configuration information encryption configuration, the renewal of Wi-Fi network inherently safe configuration, and its convenience will still be benefited from processing method provided by the invention.For example, an access configuration information Crypted password can be set, and by the channel outside Wi-Fi configure to be hopeful on its Wi-Fi equipment that can correctly resolve access configuration information frame, cryptographic algorithm has been used WEP algorithm.STA, when sending access configuration information frame, is used WEP algorithm to the data encryption of access configuration information, and in access configuration information frame, WEP position is set.The key that WEP algorithm is used, is not the WEP authenticate key that Wi-Fi network is used, but the Crypted password of access configuration information.Like this, be only set up access configuration information Crypted password by the Wi-Fi equipment of method of the present invention, could correctly resolve access configuration information frame.
