In currently existing scheme, the package of IP address is carried to be broadcasted by user terminals such as smart mobile phones, it is necessary to
According to communication code agreement, the information such as IP address are packaged, coding, cipher mode among these is complex, is limited by
The process performance of user terminal, distribution efficiency are low.And the data volume of codified is very little, and usual supported Password Length is less than
32.For example, domestic contrast commonly matches network technology at present, generally also just supports 31 code lengths, can not still solve
The problem of SSID of router device is hidden during distribution.
In the present embodiment, SSID information is no longer carried by the content in data packet, and each character is converted to
The data packet of different length is broadcasted, and carries out character recognition by the length of data packet, to complete to send out to smart machine
The purpose for sending SSID need not carry out data packet the work of coding and decoding, and need to only pass through encoding value and data packet length
Mapping relations, which carry out simple queries, can obtain distribution information, i.e., " coding, decoding " process in the present embodiment, is only according to number
According to a series of processing that packet length carries out, relative to " coding, decoding " process to data packet itself, the present embodiment is simpler
And be easily achieved, it is suitble to realize on the limited user terminal of function.
Also avoid router device problem actively exposed during distribution, during realizing distribution, routing
Device equipment need not actively send other data with security risks other than the data packet that forwarding user terminal is sent out
Packet, the problem of also avoiding maliciously to be scanned, improves the safety with network process, protects the privacy of user.
It is described that distribution information is encoded to obtain encoding value in the present embodiment, step S1, specific implementation side
Formula may include：
Character in the distribution information is encoded, each character is obtained and corresponds to encoding value.And according to described each
A character corresponds to encoding value, generates the code field of each encoding value.
Wherein, the code field of an encoding value includes：It indicates the field of character position and indicates the word of character content
Section.
In the present embodiment, the distribution information further includes the service set (SSID), the service set
(SSID) character is encoded to obtain the encoding value of the service set (SSID), described by service set
(SSID) data packet that conversion obtains includes the data packet of the encoding value of the corresponding service set (SSID).
It is described to broadcast identified data packet outward, including：It will be by the encrypted message and service set (SSID)
Obtained data packet is converted to broadcast outward, wherein.
Provided in the present embodiment it is a set of efficiently match fidonetFido, which includes the improvement for packet frame structure,
Due to need not be disassembled to data packet, and corresponding information is only indicated by the length of data packet, therefore simplifies coding
Mode, and can support the Password Length of 32 SSID length+64, during realizing distribution, user terminal can
Broadcast SSIDs and encrypted message simultaneously.
In the practical application of the present embodiment, 802.11 protocol of wireless local area network can be based on, designs and is suitable for
802.11 agreements, it is used for the frame format of distribution, than as shown in Table 1：
Table 1
Wherein Frame Body are encryption information, and data can not be parsed by monitoring end；And other fields are wireless
Field defined in LAN protocol, user terminal lack of competence modify to it.So can not be added in frame format effectively
Information.Therefore, changed to pass character information by data packet length (length) in the present embodiment.
Specifically, the code field for generating each encoding value, including：Generate the first code field of encoding value
To N code fields.
Wherein, an encoding value is encoded to the combination of multiple code fields, includes to indicate in each code field
The field of character position and the field for indicating character content, indicate that the field of character content is divided into the first content field
To the N content fields, the i-th content field is written with the i-th code field, 1≤i≤N, 2≤N and be positive integer.In this reality
It applies in example, indicates that the field of character position is properly termed as No. turn；Indicate that the field of character content can be interpreted as data packet
Length value.No. Turn it is specific effect be：As the sequence identification of character in distribution information, i.e. distribution information is specifically by multiple
Character composition, a series of character includes the information such as SSID and password.And it is needed when due to user terminal wide by cycle
The form of unicast packets sends these information, it is therefore desirable to can determine that each character is believed in distribution during cycling through
Correct position in breath marks correctly sequence, and marks the uniqueness of the data packet, to prevent out of order mistake.
Such as：One No. turn occupies 6 bit, and 64 different numbers can be represented from 000000 to 111111
Value.Such as：The format of one code field includes XXXXXX (No. turn) YYY (long data packet angle value), wherein X, Y are
Binary number.Long data packet angle value is to indicate the field of character content, since long data packet angle value is 3 in a code field
It is bit a, to the character for being 6 bit by describing an encoding value, then need two code fields, such as character
It is 110 111 by the encoding value that base64 is encoded, then needs to send 2 code fields.One is needed to pass
Defeated character finally needs the data packet number broadcasted corresponding with the quantity of the code field of character, and a code field passes through
The data packet of one specific length is sent, and the length of data packet represents the occurrence of code field, such as： 111111+
This 2 code fields of 110 and 111110+111, need to transmit is that 111111110 and 111110111 the two values correspond to
Data packet.
It is respectively 2 No. turn that 111111 and 111110 before field, which can be seemed, and subsequent 110 He of field
111, that is, form encoding value 110 111.Therefore in this example, a character needs to pass 2 times, and supported character is
64/2=32, because No. turn 6bit in total, there can be 64 different numerical value, but since one character of transmission needs 2
A No. turn, therefore it is 32 characters that can actually transmit.And the length of code field is 6+3=9bit length.
And in practical applications, corresponding original character, after being converted into base64 encoding values due to original character, obtained coding
Numerical value can become more, therefore the significant character that actual user can input only has 22.
Since during transmitting a character, the number of 1 No. turn reuse is more, then needs the data passed
Bao Yue is more, and packet loss is also lower, it is contemplated that packet loss and efficiency of transmission, the present embodiment provides several possible encoding schemes：
Specifically, indicating character bit in the field to jth code field of expression character position in first code field
The field set is identical, wherein 2≤j≤N.1 No. turn be used to send a character, i.e., No. turn with 2 times.
Due to carrying out distribution by the way of giving out a contract for a project using user terminal broadcast, user terminal can not directly confirm smart machine
Whether wifi module end has received broadcast packet, and packet loss must also occur during packet receiving in the wifi module of smart machine, no
Disposably all broadcast packets may all be received.User terminal needs continuous circulating repetition to send broadcast packet.So wide
The encryption algorithm for broadcasting packet is the key that broadcast distribution in the present embodiment.
The length of Wifi broadcast packets is had maximum packet to be limited by WiFi agreements, if just needing to split more than maximum packet limitation, one
Denier fractionation assembles then pretty troublesome again, because each packet is required for sending successfully completely, needs constantly to retransmit.Therefore codified digit
Longest can be 10bit, if bit very little, the character quantity of codified again can be very little, so being devised in the present embodiment
Several efficient encryption algorithms below：
One：The coding mode of one frame 9bit length indicates that the field of character position occupies 6 bits, indicates word
The field for according with content occupies 3 bits.It is as shown in Table 2：
Table 2
Secondly：The coding mode of one frame 10bit length, as shown in table 3：
It indicates that the field of character position occupies 7 bits, indicates that the field of character content occupies 3 bits.Such as table 3
Shown in：
Table 3
In a preferred approach, N=j=2 is embodied as the scheme of the scheme 3- extensions 1 in table 3.The effective of its support can
Code character is most, and receiving efficiency can also be met the requirements, and broadcasts general length in the case that network state is good
The distribution information of SSID+ passwords can realize distribution success within 20S.
The data packet that the corresponding encoding value is determined based on above-mentioned coding mode, described in step S2, is specifically included：
According to the mapping relations of the length of the data packet and each encoding value, inquiry obtains corresponding to the data packet of the encoding value.
For example, being carried out by taking the frame of 10bit length as an example, each bit of effect is as shown in table 4：
Table 4
In general, 32 characters can be arranged in the SSID maximums of router device, 64 characters can be arranged in password.In order to the greatest extent
The possible usage scenario for meeting user needs to be extended " the scheme used described in table 3 to existing coding mode
3- extensions 1 ", 2 data packets of No. Turn transmission, can meet the usage scenario of user in this way.Expand by the present embodiment
Encryption algorithm after exhibition, SSID can support 32 character lengths, password that can support 64 character lengths.
In currently existing scheme, when carrying out distribution into behavior smart machine by user terminals such as smart mobile phones, to protect
The safety for hindering router device then needs the SSID for hiding router device, therefore can not just be forwarded by wireless router
Multicast packets, therefore the resource of router can not be utilized when the multicast distribution of the ends smart mobile phone APP, it is supported as the wifi of smart mobile phone
Maximum rate is excessively high to will appear the case where distribution fails, mainly since multicast mode can only mix the maximum rate of 150m.
In practical application, the maximum rate that the wifi of some smart mobile phones is supported is 150m, and some is then 300m.
And net mode is matched in the broadcast used in the present embodiment, due to the forwarding resource using router, after router forwarding
The problem of rate is 1Mbps, and the packet sending speed for having extenuated current mobile phone is more than wifi module range of receiving, compatible difference wifi
The mobile phone of performance, therefore 150m and 300m this 2 kinds of rates can mix.
And in currently existing scheme, the package of IP address is carried to be broadcasted by user terminals such as smart mobile phones, just
It needing, according to communication code agreement, to be packaged the information such as IP address, coding, cipher mode among these is complex, by
It is formed on the process performance of user terminal, distribution efficiency is low.
And the data volume of codified is very little, and usual supported Password Length is less than 32.For example, current domestic contrast
Commonly match network technology, generally also just supports 31 code lengths, can not still solve to hide router during distribution
The problem of SSID of equipment.
On the problem of hiding the SSID of router device, since the code length that existing distribution algorithm is supported is very short,
User terminal can not send SSID.Therefore it needs router device to be in scanned state, and actively receives smart machine
Scanning, in order to which smart machine is obtained by scanning the SSID of router device.And this process can so that router device is sudden and violent
Reveal the information such as the SSID of oneself, if occurring other malicious users in wireless network range simultaneously, router device can be revealed
SSID, the problem of to cause safety.
In the present embodiment, SSID information is no longer carried by the content in data packet, and each character is converted to
The data packet of different length is broadcasted, and carries out character recognition by the length of data packet, to complete to send out to smart machine
The purpose for sending SSID need not carry out data packet the work of coding and decoding, and need to only pass through encoding value and data packet length
Mapping relations, which carry out simple queries, can obtain distribution information, i.e., " coding, decoding " process in the present embodiment, is only according to number
According to a series of processing that packet length carries out, relative to " coding, decoding " process to data packet itself, the present embodiment is simpler
And be easily achieved, it is suitble to realize on the limited user terminal of function.
The problem of can not sending SSID caused by being limited by code length in the prior art is also breached simultaneously, support
Codified number of characters is enough, can send SSID, and more information will also be added wherein for future provides possibility, extends
Use scope.
Also avoid router device problem actively exposed during distribution, during realizing distribution, routing
Device equipment need not actively send other data with security risks other than the data packet that forwarding user terminal is sent out
Packet, the problem of also avoiding maliciously to be scanned, improves the safety with network process, protects the privacy of user.

Specifically, an encoding value includes the first code field to N code fields, wherein the i-th content field is written
I-th code field, 1≤i≤N, 2≤N and be positive integer are described to indicate that the field of character content is divided into described first
Hold field to the N content fields.
Further, it indicates to indicate character in the field to jth code field of character position in first code field
The field of position is identical, wherein 2≤j≤N.
In a preferred approach, it indicates that the field of character position occupies 7 bits, indicates that the field of character content occupies 3
A bit, and N=j=2.
