It is described in detail below in step S101 and each character in the first character string and the second character string is compiled respectively Code, obtains a kind of implementation of the corresponding IP address of each character.
Specifically, as shown in Fig. 2, according to the following steps, obtaining each character pair in the first character string and the second character string The IP address answered:
S1011 determines the first predetermined bit position of the corresponding IP address of character according to the classification of character string where character Value；
Wherein, for any character to be encoded, if the character is the character in the first character string, word where the character The classification of symbol string is service set, if the character is the character in the second character string, the classification of character string where the character For password；
S1012 determines the second predetermined bit position of the corresponding IP address of character according to serial number of the character in character string Value；
S1013 determines the value of the third predetermined bit position of the corresponding IP address of character according to the content of character；
Wherein, the sum of the first predetermined bit position, the second predetermined bit position and digit of third predetermined bit position are by IP What the mapping relations of location and MAC Address determined.In one implementation, the mapping relations of IP address and the address MAC can be with Are as follows: it is low 23 bit that low 23 bit of IP address is copied directly to MAC Address when IP address is mapped to MAC Address Position.
It, can be with by the bit sum of the mapping relations and IP address of IP address and MAC Address in a kind of implementation It determines in IP address for identifying the bit of the coding result of character.
For example, IP address is 32 bits, and when IP address is mapped to MAC Address is by low the 23 of the address IP Bit is copied directly to low 23 bit of MAC Address, then can be used to identify character for low 23 bit of IP address Coding result, and fixed value is set by high 9 bit of IP address.Due to the IP address in multicast high 4 bit always 1110, therefore the most-significant byte that IP address can be set is fixed value, range is 224~239.And the 23rd bit of IP address It can be set to fixed value, such as be set as 0 or for 1.
In bit in IP address for the coding result for identifying character, the first predetermined bit position can be used to mark The classification of character string where remembering character, that is, marking the character is to be located in service set or be located in password, pre- by second If bit is used for serial number of the tab character in character string, third predetermined bit position is used for tool represented by tab character Hold in vivo.
For the first predetermined bit position, for example, if IP address is 32 bits and low 23 bit is used for identifier word The coding result of symbol, can using 1 bit of IP address as the first predetermined bit position, such as the 22nd bit, specifically: 22nd bit is 0, and character string where indicating character is service set, and the 22nd bit is 1, indicates character string where character For password.It can also be using two bits in IP address as the first predetermined bit position, such as the 22nd, 21 bits, specifically Are as follows: the 22nd, 21 bits be 00, indicate character where character string be service set, the 22nd, 21 bits be 01, indicate word Character string where symbol is password.Certainly, in the specific implementation, the digit of the first predetermined bit position and position can as required into Row setting, it is not limited in the embodiment of the present invention.
For the second predetermined bit position, for example, if IP address is 32 bits and low 23 bit is used for identifier word The coding result of symbol, can be using several bits in low 23 bit in addition to the first predetermined bit position as the second default ratio Special position.By taking the digit of the second predetermined bit position is 3 as an example, second predetermined bit position can be expressed as 000 when serial number is 1, suitable Second predetermined bit position can be expressed as 001 when serial number 2, and so on.It should be understood that the digit of the second predetermined bit position It is related to the quantity for the character that character string at most may include, if the character quantity that character string at most may include is more, second The digit of predetermined bit position is more.In the specific implementation, the digit of the second predetermined bit position and position can carry out as required Setting, it is not limited in the embodiment of the present invention.
In a specific embodiment, the 23rd~16 bit of IP address is as shown in table 1, wherein the 23rd bit The 0, the 22nd bit of fixed value is redefined for as the first predetermined bit position, wherein the character string where character is services set mark The 22nd bit is 0 when knowledge, and the 22nd bit is 1 when the character string where the character is password, and the 21st~16 bit is as the Two predetermined bit positions.That is, the 23rd~16 bit of IP address can be used for distinguishing SSID and PWD.
Table 1
When being encoded in the manner as shown in table 1, for the 2nd character in service set, the IP that is obtained after coding The 23rd~16 bit is 000000001 (with decimal representation for 1) in address, for the 2nd character in password, after coding To IP address in the 23rd~16 bit be 010000001 (with decimal representation for 65).
For third predetermined bit position, third predetermined bit position is for particular content represented by tab character, in one kind In implementation, can by searching for character under pre-arranged code regular (such as ASCII coding) corresponding to binary digit, with Value of the binary digit found as third predetermined bit position.In this mode, the digit of third predetermined bit position can To be determined by pre-arranged code rule.
In another implementation, the quantity that can preset third predetermined bit position is more than or equal to 16, then exists The above-mentioned content according to character can in the step S1013 for determining the value of the third predetermined bit position of the corresponding IP address of character To include:
It is two bytes by character code, wherein the first code value according to the high nibble and low nibble of the first code value Are as follows: character corresponding code value in pre-arranged code rule；
According to two bytes after coding, the value of the third predetermined bit position of the corresponding IP address of character is determined.
