Background
The main networking mode of the current Internet of things equipment is completed through an embedded Internet of things identity recognition module of the equipment. And the internet of things identity recognition module uses code number data locally stored by the module to perform internet-surfing authentication processing with the mobile communication network, if the authentication is successful, the internet of things equipment is successfully processed, otherwise, the internet of things equipment is failed to process.
The fixed formal code numbers are basically not opened when the Internet of things equipment is placed, and the application and the downloading of the remote code numbers can be carried out to the Internet of things operation background only when the application is formally started. The remote code number application and the downloading operation can be finished only by networking successfully in advance, so that a temporary code number for supporting the remote code number application and the downloading operation is preset on an embedded internet of things identity recognition module when equipment is laid out, and the temporary code number is called as a seed code number.
The network-logging rule of the mobile communication network can know that the network is successfully logged in by using the same code number data, and at most, only one network-on device exists, so that the same number of code number data needs to be applied for serving as seed code numbers according to the total amount of the internet of things identity recognition modules of the current batch before a batch of devices are distributed in the conventional case. However, with the development of the internet of things service, we gradually find that the one-module one-number processing mode has the following two problems: 1. because the seed code numbers corresponding to each module are different, when the module is initialized, the corresponding relation between each group of seed code numbers and the module identification needs to be checked, so that the initialization execution speed is slow; 2. the number of the seed code numbers is consistent with the number of the modules, but the seed code numbers are only used in the initial network access stage of the equipment, so that a large number of seed code numbers are idle, and the management cost and the management difficulty of the seed code numbers are increased.
In addition, the data statistics through practical application also finds that the devices distributed in the same batch rarely start the application and downloading operation of the remote code number to the operation background of the internet of things at the same time, that is to say, the probability of simultaneously surfing the internet and surfing the internet of things is very low.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
When an internet of things operator lays out a lot of internet of things equipment, a lot of seed code numbers with the total quantity far smaller than that of the lot of equipment, namely the total quantity of the internet of things identity recognition modules, are applied in advance and collected into a first seed code number list, and the first seed code number list is uniformly set on each internet of things identity recognition module in advance through the seed code number management method of the internet of things identity recognition module provided by the embodiment of the invention; when each internet of things identity recognition module starts a network login operation, inquiring a code number state to confirm whether the current module finishes the downloading of a formal code number or not by the method provided by the embodiment of the invention, if not, using a matched seed code number to perform the network login processing according to the equipment identification number-hash code-seed code number matching mechanism provided by the embodiment of the invention, and after the network login is successful and the application and the downloading operation of a remote code number are successful, modifying the code number state of the module into a non-initial code number state to identify that the current module finishes the downloading of the formal code number; fig. 1 is a schematic diagram of a seed code number management method of an identity recognition module of the internet of things according to a first embodiment of the present invention, where, as shown in fig. 1, the method mainly includes the following steps:
Step 101, an internet of things identity recognition module acquires first code number state data;
the internet of things identity recognition module comprises a user identity recognition module (Subscriber Identity Module, SIM), an embedded subscriber identity recognition module (eSIM) and a virtual subscriber identity recognition module (vSIM); the first code number state data includes an initial code number state and a non-initial code number state.
If the first code number state data is the initial code number state, it is indicated that the current internet of things identity recognition module has not successfully downloaded the formal code number data, and the corresponding current internet of things equipment has not formally started the application, and the current internet of things identity recognition module is required to execute the subsequent steps 102-109 to select a matched seed code number from a preset first subcode number list to log on, and initiate the application and downloading operation of the remote code number to the internet of things operation background after the successful log on; if the first code number state data is in a non-initial code number state, the current internet of things identity recognition module is indicated to have successfully downloaded the formal code number data, and then the current internet of things identity recognition module does not need to execute subsequent steps 102-109, but directly transfers to other steps to perform internet surfing operation by taking the downloaded formal code number data as the internet surfing basis.
102, when the first code number state data is the initial code number state, acquiring first equipment identification data;
wherein the first equipment identification data at least comprises first equipment international mobile equipment identification (International Mobile Equipment Identity, IMEI) data and first equipment product Serial Number (SN) data; the data format of the first device identification data is a character string composed of american standard information interchange code (American Standard Code for Information Interchange, ASCII) characters; the first device identification data has a single ASCII code character ranging from "0" to "9";
here, the first equipment identification data is unique identification information of the internet of things equipment where the current internet of things identity module is located; the character information of the first device identification data does not contain other character information than "0" - "9".
Step 103, according to a preset first hash code algorithm identification, corresponding hash code calculation is carried out on the first equipment identification data, and corresponding first hash code data are generated;
the first hash code algorithm identification comprises a BKDRHAsh algorithm identification, an APHash algorithm identification, a DJBH (digital hash) algorithm identification, a JSHash algorithm identification and a RSHash algorithm identification; the first hash code algorithm identification defaults to a bkdrhh algorithm identification.
Specifically, when the first hash code algorithm identifier is a BKDRHAsh algorithm identifier, BKDRHAsh hash code calculation is performed on the first equipment identifier data, and corresponding first hash code data is generated; when the first hash code algorithm identifier is an APHash algorithm identifier, carrying out APHash hash code calculation on the first equipment identifier data to generate corresponding first hash code data; when the first hash code algorithm identifier is DJBH algorithm identifier, DJBH hash code calculation is carried out on the first equipment identifier data to generate corresponding first hash code data; when the first hash code algorithm identifier is a JShash algorithm identifier, performing JShash hash code calculation on the first equipment identifier data to generate corresponding first hash code data; when the first hash code algorithm identifier is an RSHash algorithm identifier, RSHash hash code calculation is conducted on the first device identifier data, and corresponding first hash code data are generated.
Here, the BKDRHAsh algorithm is written in Brian Kernighan and Dennis ritche, issued in The C Programming Language; the APHash algorithm is a hash algorithm issued by Arash Partow; the DJBH algorithm is a hash algorithm published by Daniel J.Bernstein professor; the JSHash algorithm is a hash algorithm issued by just Sobel; the source of the RSHash algorithm is the book Algorithms in C issued by Robert Sedgwicks. Among the hash algorithms, the BKDRHAsh algorithm is the one with the smallest collision rate (the probability that hash values obtained by calculating different input data through the algorithm are the same), so in the embodiment of the invention, the BKDRHAsh algorithm is used as a default algorithm, in the conventional case, especially under the condition that the total number of the seed codes of the batch is smaller, the first hash code algorithm identifier is set as the BKDRHAsh algorithm identifier, and if the total number of the seed codes of the batch is larger, any one of the other algorithms can be adopted as the hash algorithm identifier of the batch.
When the first hash code algorithm identifier is a BKDRHash algorithm identifier, performing corresponding hash code calculation on the first device identifier data according to a preset first hash code algorithm identifier, and generating corresponding first hash code data, wherein the method specifically comprises the following steps of:
step 1031, according to a preset character interception length, performing sub-string interception processing on the first equipment identification data to generate a first sub-string sequence;
wherein the first substring sequence comprises a plurality of first substrings; the character length of the first substring is the character interception length;
here, the character interception length is a preset system parameter; as can be known from the disclosed BKDRHAsh algorithm, if the input data sequence of the algorithm is too long, the calculated amount of the algorithm can be increased in an exponential relation; in order to reduce the calculation amount, the embodiment of the invention can use the character interception length to adjust the length of the input data sequence in actual calculation; if the character length of the first equipment identification data is considered to be moderate, the character interception length can be set to be 1, and the length of the input data sequence of the BKDRHAsh algorithm is the same as the character length of the first equipment identification data; if the character length of the first device identification data is considered to be too long, the character interception length can be set to be a value which can be divided by the character length of the first device identification data, the character interception length is used for segmenting the first device identification data, each segment is used as input data to form an input data sequence, and the length of the input data sequence is changed into the total segmentation after the processing: input data sequence length=first device identification data character length/character interception length, input data sequence length is reduced, and the calculation amount of a natural algorithm is reduced;
For example, if the first device identification data is IEMI number "100000011111111", the character interception length is 1; then, the first substring sequence obtained by this step is "1", "0", "0", "0", "0", "0", "1", "1", "1", "1", and "1"), where the first substring sequence contains 15 first substrings, and each first substring has a length of 1;
for another example, if the first device identification data is IEMI number "100000011111111", the character interception length is 3; then, the first substring sequence obtained by this step is ("100", "000", "011", "111", "111"), where the first substring sequence contains 5 first substrings, each of which has a length of 3;
for another example, if the first device identification data is SN number "100000011111111", the character cut length is 5; then, the first substring sequence obtained by this step is ("10000", "00111", "11111"), where the first substring sequence contains 3 first substrings, and the length of each first substring is 5;
Step 1032, performing character value conversion processing on each first sub-string to generate a corresponding first data element;
for example, if the first device identification data is IEMI number "100000011111111", the character interception length is 1, and the first substring sequence is "1", "0", "0", "0", "0", "1", "1", "1", "1", "1", "1", "1"); then, the 15 first data elements obtained by this step are: 1, 8, 9, 10, 11, 12, 13, 14, 15 first data elements are 1, and 2, 3, 4, 5, 6, 7 first data elements are 0;
for another example, if the first device identification data is IEMI number "100000011111111", the character interception length is 3, and the first substring sequence is ("100", "000", "011", "111", "111"); then, the 5 first data elements obtained by this step are: first data element 100 1, first data element 000 2, namely 0, first data element 011 3, namely 11, first data element 111 4, first data element 111 5;
for another example, if the first device identification data is SN number "100000011111111", the character cut length is 5, and the first substring sequence is "10000", "00111", "11111"); then, the 3 first data elements obtained by this step are: first data element 1 10000, first data element 2 00111 is 111, first data element 3 11111;
Step 1033, if the first data element is zero, modifying the first data element to a preset first non-zero factor;
here, the hash code collision probability calculated by the bkdrhh algorithm under the condition that the element value is 0 will be improved, and in order to avoid this situation, in the embodiment of the present invention, the first data element with the value of 0 is set to be a first non-zero factor, where the first non-zero factor is a preset system parameter with a non-zero value, and is set to be 1 in a conventional case;
for example, if the first device identification data is IEMI number "100000011111111", the character interception length is 1, the first substring sequence is "1", "0", "0", "0", "0", "1", "1", "1", "1", "1"), and the 15 first data elements are: the 1 st, 8 th, 9 th, 10 th, 11 th, 12 th, 13 th, 14 th and 15 th first data elements are all 1, the 2 nd, 3 rd, 4 th, 5 th, 6 th and 7 th first data elements are all 0, and the first non-zero factor is 1; because the values of the 2 nd to 7 th first data elements are all 0, the step changes the value of the 2 nd to 7 th first data elements from 0 to 1;
for another example, if the first device identification data is IEMI number "100000011111111", the character interception length is 3, the first substring sequence is ("100", "000", "011", "111", "111"), and the 5 first data elements are: first data element 100 1, first data element 000 2, namely 0, first data element 011 3, namely 11, first data element 111 4, first data element 111 5, the first non-zero factor being 1; because only the value of the 2 nd first data element is 0, the step changes the value of the 2 nd first data element from 0 to 1;
For another example, if the first device identification data is SN number "100000011111111", the character cut length is 5, the first substring sequence is ("10000", "00111", "11111"), and the 3 first data elements are: first data element 1 10000, first data element 2 00111 is 111, first data element 3 11111, and the first non-zero factor is 1; because there are no first data elements with a value of 0, this step does not modify any of the first data elements;
a step 1034 of composing a first data element sequence from the obtained plurality of first data elements;
here, the first data element sequence is the input data sequence of the BKDRHash algorithm mentioned above;
for example, if the first device identification data is IEMI number "100000011111111", the character interception length is 1, the first data element sequence is (1,1,1,1,1,1,1,1,1,1,1,1,1,1,1); at this time, the length of the input data sequence of the BKDRHash algorithm is the first equipment identification data character length/character interception length=15/1=15;
for another example, if the first device identification data is IEMI number "100000011111111", and the character interception length is 3, the first data element sequence is (100,1,11,111,111); at this time, the length of the input data sequence of the BKDRHash algorithm is the first equipment identification data character length/character interception length=15/3=5;
For another example, if the first device identification data is SN number "100000011111111" and the character cut length is 5, the first data element sequence is (10000,111,11111); at this time, the length of the input data sequence of the BKDRHash algorithm is the first equipment identification data character length/character interception length=15/5=3;
step 1035, sending the first data element sequence to a preset BKDRHAsh algorithm interface for hash code calculation to generate first hash code data.
Here, for the first sequence of data elements (a 1 ,…A i ,…A N ) For example, the first hash code data calculated by the bkdrhh algorithm interface should beWhere i has a value of 1 to N, N is a first device identification data character length/character interception length, size is a maximum value of the first hash code data, default to 0x7fffffff, seed is a prime seed parameter (such as 31, 131, 1313, 13131, etc.) of BKDRHash algorithm,&is a bitwise AND operator.
For example, if the first data element sequence is (1,1,1,1,1,1,1,1,1,1,1,1,1,1,1), seed=31, phase is 0x7FFFFFFF; then n=15, first hash code data= (1×31 14 +1*31 13 +1*31 12 +1*31 11 +1*31 10 +1*31 9 +1*31 8 +1*31 7 +1*31 6 +1*31 5 +1*31 4 +1*31 3 +1*31 2 +1*31 1 +1*31 0 )&0x7FFFFFFF；
For another example, if the first data element sequence is (100,1,11,111,111), seed=31, phase is 0x7FFFFFFF; then n=5, first hash code data= (100×31 4 +1*31 3 +11*31 2 +111*31 1 +111*31 0 )&0x7FFFFFFF；
For another example, if the first data element sequence is (10000,111,11111), seed=31, phase is 0x7FFFFFFF; then n=3, first hash code data= (10000×31 2 +111*31 1 +11111*31 0 )&0x7FFFFFFF。
Step 104, according to the first hash code data, inquiring a first corresponding relation table reflecting the corresponding relation between the hash code and the seed code number to obtain corresponding first seed code number identification data;
the first corresponding relation table comprises a plurality of first corresponding relation records; the first correspondence record includes a first hash code field and a first subcode number identification field;
the method specifically comprises the following steps: polling the first corresponding relation record of the first corresponding relation table, and taking the currently polled first corresponding relation record as a first current record; and if the first hash code field of the first current record is matched with the first hash code data, extracting the first subcode number identification field of the first current record as first subcode number identification data.
Here, the first correspondence table is set together when the first subcode number list is set for the internet of things identity recognition module; the first corresponding relation table is used for storing a plurality of first corresponding relation records reflecting the corresponding relation between the hash codes and the seed code numbers; each first corresponding relation record corresponds to one piece of hash code information; the calculation mode of the hash code information is consistent with the calculation mode of the step 103; the first hash code field of the first corresponding relation record is used for storing the hash code information corresponding to the current record, and the first subcode number identification field is used for storing the identification information of the seed code number corresponding to the hash code of the current record. It should be noted that, because each piece of hash code information is calculated based on the first device identification data of the current internet of things identity module, and the first device identification data of each piece of internet of things identity module is known to be different, the content of the first correspondence table of each piece of internet of things identity module should be different.
Step 105, inquiring a preset first sub-code number list according to the first sub-code number identification data, and generating corresponding first sub-code number data;
the first subcode number list comprises a plurality of first subcode number records; the first subcode number record comprises a second subcode number identification field and a first subcode number field;
the method specifically comprises the following steps: polling a first subcode number record of the first subcode number list, and taking the first subcode number record currently polled as a second current record; and if the second subcode number identification field of the second current record is matched with the first subcode number identification data, extracting the first subcode number field of the second current record as the first subcode number data.
Here, the first subcode number list is used for storing seed code numbers applied by the internet of things operator for the lot of internet of things identity recognition modules, and each first subcode number record corresponds to one seed code number; as can be seen from the foregoing, the contents of the first subcode number list set on the identity recognition modules of the internet of things in the same batch should be the same, and the total amount of the first subcode number records of the first subcode number list should be far less than the total amount of the identity recognition modules of the internet of things in the same batch; in the first sub-code number record, the second sub-code number identification field is used for storing identification information of a seed code number corresponding to the current record, and the first sub-code number field is used for storing seed code number information corresponding to the current record.
And 106, performing internet of things equipment surfing processing according to the first seed code number data.
Specifically, the internet of things identity recognition module calculates internet-surfing authentication data by using an internet-surfing authentication processing flow of the mobile communication network corresponding to the first seed code number data, obtains corresponding authentication data and sends the corresponding authentication data to the corresponding mobile communication network;
the mobile communication network analyzes the authentication data to obtain first seed number data; inquiring whether a code number matched with the first seed code number data exists in the current network code number resource; if the network connection success state information does not exist, returning the network connection success state information to the identity recognition module of the Internet of things; if yes, returning network access failure state information to the identity recognition module of the Internet of things;
the identity recognition module of the Internet of things recognizes the returned information of the mobile communication network; if the returned information is the successful network login state information, judging that the network login processing of the Internet of things equipment is successful; if the returned information is the network access failure state information, judging that the network access processing of the Internet of things equipment fails.
When the internet of things equipment logs in, the internet of things identity recognition module performs internet surfing authentication interaction with the mobile communication network corresponding to the code number by using the currently obtained first seed code number data.
Step 107, identifying whether internet-of-things equipment internet surfing processing is successful; if the internet of things equipment fails to log on, the step 108 is performed; if the internet of things device is successful, the process goes to step 109.
If the internet of things equipment fails to log in, it is indicated that the first seed code number data used by the current internet of things identity module may have a log-in collision, that is, a module in the current network has completed logging in the network with the code number and is kept in a network state, then the current internet of things identity module will go to step 108 to perform fine tuning on the first equipment identification data, and the purpose of the present internet of things identity module is to continue to perform a log-in attempt with the seed code number corresponding to the fine-tuned first equipment identification data; if the internet of things device successfully logs in, it is indicated that the first seed code number data used by the current internet of things identity recognition module does not have a log-in collision, and then the process naturally goes to step 109 to start the application and downloading operation of the remote code number.
Step 108, performing increment processing on the current first equipment identification data according to a preset first increment factor to obtain new first equipment identification data, and turning to step 103;
here, after the current first seed number data causes the network connection collision, if the network connection attempt is to be continued, a new seed number needs to be selected from a plurality of seed numbers in the first seed number list; since each seed code number corresponds to one hash code data, a new hash code needs to be calculated; the calculation modes of the hash code are consistent with those of the step 103, and if a new hash code different from the hash code calculated in the previous step 103 is to be obtained, the first equipment identification data is required to be finely adjusted; the current step 108 is a processing step of fine tuning the first device identification data according to the embodiment of the present invention;
The method specifically comprises the following steps: step 1081, using the rightmost first number of characters of the current first device identification data as delta characters;
here, the first number is a preset system parameter, and the minimum value is 1;
for example, if the first device identification data is "1234567890112345", and the first number is 1, the delta character is the rightmost "5";
for another example, if the first device identification data is "123456789012309" and the first number is 1, then the delta character is the rightmost "9";
for another example, if the first device identification data is "123456789012309", and the first number is 2, then the delta character is "09" on the far right;
step 1082, performing numerical conversion processing on the increment character to generate first data;
for example, if the first device identification data is "1234567890112345", the first number is 1, the delta character is the rightmost "5", then the first data is 5;
for another example, if the first device identification data is "123456789012309", the first number is 1, the delta character is "9" on the far right, and then the first data is 9;
for another example, if the first device identification data is "123456789012309", the first number is 2, the delta character is "09" on the far right, and the first data is 9;
Step 1083, calculating a sum of the first increment factor and the first data to generate second data;
here, the first increment factor is a preset system parameter, which is conventionally set to 1;
for example, if the first device identification data is "1234567890112345", the first number is 1, the first data is 5, and the first increment factor is 1, the second data is 5+1=6;
for another example, if the first device identification data is "123456789012349", the first number is 1, the first data is 9, and the first increment factor is 1, the second data is 9+1=10;
for another example, if the first device identification data is "123456789012309", the first number is 2, the first data is 9, and the first increment factor is 1, the second data is 9+1=10;
step 1084, performing a string conversion process on the second data to generate a first string; and taking the first number of characters on the rightmost side of the first character string as replacement characters;
for example, if the first device identification data is "1234567890112345", the first number is 1, the first data is 5, the first increment factor is 1, the second data is 6, the first string is "6", the right 1 character of the first string "6" is used as the replacement character, and the replacement character is "6";
For another example, if the first device identification data is "123456789012349", the first number is 1, the first data is 9, the first increment factor is 1, the second data is 10, the first string is "10", the right 1 character of the first string "10" is used as the replacement character, and the replacement character is "0";
for another example, if the first device identification data is "123456789012309", the first number is 2, the first data is 9, the first increment factor is 1, the second data is 10, the first string is "10", the right 2 characters of the first string "10" are used as replacement characters, and the replacement characters are "10";
step 1085, replacing the delta character of the current first device identification data with the replacement character to obtain new first device identification data; and proceeds to step 103.
For example, if the first device identification data is "1234567890112345", the first number is 1, the increment character is "5" on the far right, and the first increment factor is 1, the replacement character is "6", and then the replacement character "6" is used to replace the increment character of the current first device identification data to obtain new first device identification data as "123456789012346"; the next step goes to step 103 to start calculating the corresponding hash code using the new first device identification data "123456789012346";
For another example, if the first device identification data is "123456789012309", the first number is 1, the increment character is "9" on the far right, and the first increment factor is 1, the replacement character is "0", and then the replacement character "0" is used to replace the increment character of the current first device identification data to obtain new first device identification data as "123456789012300"; the next step goes to step 103 to start calculating the corresponding hash code using the new first device identification data "123456789012300";
for another example, if the first device identification data is "123456789012309", the first number is 2, the increment character is "09" on the far right, and the first increment factor is 1, the replacement character is "10", and then the replacement character "10" is used to replace the increment character of the current first device identification data to obtain new first device identification data as "123456789012310"; the next step then goes to step 103 to begin calculating the corresponding hash code using the new first device identification data "123456789012310".
From the processing mechanism of step 108, it can be further seen that the first number and the maximum value of the total number of seed codes in the embodiment of the present invention are logarithmic: first quantity = log 10 (maximum total seed number), the total seed number can be controlled by controlling the first number; when the seed number resource is tense, the first number can be set smaller, and when the seed number resource is abundant, the first number can be setThe quantity setting is large.
For example, if the first number is preset to 1, the adjustable characters of the first device identification data are limited to only the rightmost 1-bit character, and all the characters of the first device identification data are known to be within the range of 10 characters of "0" - "9", so that the first device identification data is 10 at most 1 The number of the seed codes on the current internet of things identity module is 10 when the first number is preset to be 1; if the first number is preset to 2, the adjustable character of the first equipment identification data is limited to the rightmost 2-bit character, and all characters of the first equipment identification data are known to be in the range of 10 characters of 0 to 9, the characters of the rightmost 2-bit character are in the range of 100 characters of 00 to 99, so that the first equipment identification data can have 10 at most 2 The number of the seed codes on the current internet of things identity module is 100 when the first number is preset to be 2; similarly, the total number of seed codes is maximum=10 First number of 。
Step 109, executing remote code number application and downloading operation, and setting the first code number status data to be a non-initial code number status after the operation is successful.
Here, when the internet of things device logon processing is successfully identified in step 107, if the internet of things device logon processing is successful, it is indicated that the first seed code number data used by the current internet of things identity recognition module does not have a logon collision, so that the current step 109 is shifted to execute the application and downloading operations of the remote code number; when remote code number application and downloading operation are executed, the internet of things identity recognition module sends code number application request data to a remote internet of things operation background; the operation background of the Internet of things performs legal authentication on the code number application request data, and if the authentication is passed, a formal code number data packet is called from the background and returned to the identity recognition module of the Internet of things; after the internet of things identity recognition module downloads the complete code number data packet, extracting the formal code number information from the complete code number data packet and updating a local code number file according to the formal code number information; if the local code number file is updated successfully, the remote code number application and downloading operation is successful, namely the current internet of things identity recognition module has picked up the code number of the formal work and has completed setting; the module then modifies the first code number state data from the initial code number state to the non-initial code number state, so that the module can log on the network with the formal code number later.
