Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a method, device, equipment and medium for generating and configuring a physical address. Background Art

[0002] Communication modules are usually installed on various hosts as network cards to support network communication. Each network card has a corresponding MAC address (Media Access Control Address, also known as LAN address, physical address). Currently, a MAC address usually consists of 6 bytes, expressed as 12 hexadecimal numbers, of which the first three bytes are called the organization unique identifier, which is used to identify the manufacturer of the device; the last three bytes are the device unique identifier assigned by the manufacturer, which is used to identify the specific device. This structure ensures the uniqueness of the MAC address.

[0003] At present, the general practice of generating and configuring MAC addresses is: 1. Burn the MAC address into the storage device, and then read the MAC address through the communication module; 2. Generate a MAC address randomly. In the first solution, the MAC address is mainly written through the serial port, USB flash drive or network port. Among them, the solution of burning the MAC address through the serial port or network port requires the upper computer software, and also requires personnel participation, which increases the process; and the solution of burning the MAC address with a USB flash drive can be completed automatically, but it requires the device to support the USB (Universal Serial Bus) interface, which is not widely applicable and has certain security risks. In addition, the above three methods require the MAC address to be planned in advance to determine the MAC address of each batch of equipment. In the second solution, the generation efficiency of randomly generated MAC addresses is low, and a lot of time is wasted. In addition, the randomly generated MAC address cannot guarantee its uniqueness, and it will be regenerated every time the machine is turned on, and the certainty of the MAC address cannot be guaranteed.

[0004] In summary, how to automatically generate and configure MAC addresses and ensure their uniqueness and certainty is a problem that needs to be solved. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a method, device, equipment and medium for generating and configuring a physical address, which can automatically generate and configure a MAC address and ensure its uniqueness and certainty.

[0018] Accordingly, the step of extracting a first preset number of characters from the addition result to generate a first physical address includes:

[0019] Taking the first position in the addition result as a starting point, continuously intercepting a first preset number of characters to generate a first physical address;

[0020] Or, starting from the second position in the added result, continuously intercept a third preset number of characters to obtain a first interception result, and starting from the third position in the added result, continuously intercept a fourth preset number of characters to obtain a second interception result, and then the first interception result and the second interception result are spliced ​​to generate a first physical address; wherein the sum of the third preset number and the fourth preset number is the first preset number.

[0021] Optionally, intercepting the digest value to generate a first physical address includes:

[0022] A second preset number of characters is intercepted from the summary value to obtain a target interception result, and a target separator is added to the target interception result according to a preset physical address format requirement to generate a first physical address; wherein the second preset number is a total number of digits determined according to the physical address format requirement.

[0023] Optionally, the extracting a second preset number of characters from the digest value to obtain a target extraction result includes:

[0024] Taking the first position in the digest value as a starting point, continuously intercepting a second preset number of characters to obtain a target interception result;

[0025] Or, starting from the second position in the digest value, continuously intercepting a fifth preset number of characters to obtain a third interception result, and starting from the third position in the digest value, continuously intercepting a sixth preset number of characters to obtain a fourth interception result, and then splicing the third interception result and the fourth interception result to obtain a target interception result;

[0030] If it is within the preset physical address range, determining that the first physical address is legal, and executing the step of writing the first physical address into the newly created physical address storage file;

[0031] If it is not within the preset physical address range, the first physical address is determined to be illegal, and the process jumps again to the step of generating a random number and calculating the random number using a preset information digest algorithm.

[0032] In a second aspect, the present application discloses a physical address generation and configuration device, which is applied to a communication module, including:

[0033] A judgment module is used to judge whether there is a physical address storage file locally after power-on;

[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0051] At present, when generating and configuring MAC addresses, the general practice is: 1. Burn the MAC address into the storage device, and then read the MAC address through the communication module; 2. Randomly generate the MAC address. In the first scheme, the MAC address is mainly written through the serial port, U disk or network port. Among them, the scheme of burning the MAC address through the serial port or network port requires the upper computer software, and also requires the participation of the personnel, which increases the process; and the U disk burning MAC address scheme, although it can be completed automatically, requires the device to support the USB (Universal Serial Bus) interface, the applicability is not wide and there are certain safety hazards, and the above three methods all need to plan the MAC address in advance to determine the MAC address of each batch of equipment. In the second scheme, the generation efficiency of randomly generated MAC addresses is low, and a lot of time is wasted. In addition, the randomly generated MAC address cannot guarantee its uniqueness, and it will be regenerated every time it is turned on, and the MAC address certainty cannot be guaranteed. For this reason, the embodiment of the present application discloses a method, device, equipment and medium for generating and configuring a physical address, which can automatically generate and configure a MAC address and ensure its uniqueness and certainty.

[0052] See also Figure 1 As shown, the embodiment of the present application discloses a method for generating and configuring a physical address, the method comprising:

[0053] Step S11: After powering on, determine whether there is a local physical address storage file.

[0054] In this embodiment, after the communication module is powered on, it is first necessary to determine whether there is a physical address storage file locally. It should be pointed out that each communication module has its own IMEI (International Mobile Equipment Identity) code, which is set by the manufacturer when it comes out, fixed and unique, one machine and one code. IMEI is used to identify each independent mobile communication device in the mobile network, similar to the ID number of each communication device. The IMEI code consists of 15 to 17 digits, of which the first 8 digits are the model approval number, which is used to distinguish the brand and model of the mobile phone; the next 2 digits are the final assembly number, which represents the code of the final assembly; the last 6 digits are the serial number, which represents the production sequence number; the last digit is the check digit, which is used to verify the correctness of the entire IMEI code.

[0055] Step S12: If the physical address storage file does not exist locally, a random number is generated, and the random number is calculated using a preset information digest algorithm to generate a digest value corresponding to the random number.

[0056] In this embodiment, if the physical address storage file does not exist locally, a random number is generated by RANDOM (random number generator), and then the random number is calculated by using a preset information digest algorithm to generate a digest value corresponding to the random number. The preset information digest algorithm may specifically include but is not limited to the MD5 algorithm (Message Digest Algorithm 5), the SHA algorithm (Security Hash Algorithm), etc. It should be noted that different data can generate a unique digest value after being processed by the preset information digest algorithm.

[0057] Furthermore, after the above-mentioned determination of whether a physical address storage file exists locally, it also includes: if a physical address storage file exists locally, reading a second physical address in the physical address storage file; configuring the second physical address to a target file node according to a preset dialing method, so that the host reads the target file node to use the second physical address as the physical address of the network card.

[0058] That is, if there is a physical address storage file locally, the second physical address in the physical address storage file is directly read. At this time, there is no need to generate a new physical address, and the second physical address is configured to the target file node (host_addr) according to the preset dialing method, so that the host reads the target file node to use the second physical address as the physical address of the network card. Specifically, after the communication module enumerates the network card on the host, the host will read the physical address in host_addr and configure it as the physical address of the host-side network card according to the usb_gadget protocol. Among them, the linux usb_gadget framework is a framework that allows user space programs to dynamically configure USB devices. It provides APIs (Application Programming Interfaces) and tools so that users can create and configure the functions of USB devices as needed; it also provides a set of sysfs interfaces so that user space programs can configure USB devices through file operations. Developers can create, modify and delete the configuration, interface and endpoints of USB devices, and set their properties, such as type, address, maximum packet size, etc.

[0059] It should also be pointed out that the communication module is usually loaded on the host as a network card device. The host will load the corresponding network card driver according to the dial-up method of the communication module. Among them, the dial-up method is generally determined according to the communication method between the communication module and the network. For example, some common network card drivers are gobinet (rmnet), cdc_ether (ecm), cdc_mbim (mbim), cdc_rndis (rndis), etc. These drivers identify the communication module through id_table (identifier table) and load it to the corresponding intf (interface), and finally provide the network card for the host enumeration to achieve communication. If a new communication module adopts the dial-up method of cdc_mbim (mbim), when it is connected to the host, the host will confirm that this is the corresponding driver type by looking up the information related to cdc_mbim (mbim) in id_table, and then load the driver to the appropriate intf, so that the host can recognize and use this new network card for communication.

[0060] Step S13: intercepting the summary value to generate a first physical address, and writing the first physical address into a newly created physical address storage file.

[0061] In this embodiment, the summary value needs to be intercepted to generate the first physical address, and the generated first physical address is written into the newly created physical address storage file. That is, the present application automatically generates the physical address through random numbers and a preset information summary algorithm, which no longer relies on manpower, and to a certain extent also ensures the uniqueness, certainty and security of the physical address.

[0062] Furthermore, after the above-mentioned interception of the summary value to generate the first physical address, it also includes: determining whether the first physical address is within a preset physical address range to perform a legitimacy check on the first physical address; if it is within the preset physical address range, determining that the first physical address is legal, and executing the step of writing the first physical address to the newly created physical address storage file; if it is not within the preset physical address range, determining that the first physical address is illegal, and jumping back to the step of generating a random number, and calculating the random number using a preset information summary algorithm.

[0063] That is, after generating the first physical address, the present embodiment needs to perform a legality check on the first physical address to ensure that the generated physical address is legal. In a specific implementation, it is mainly to determine whether the generated first physical address is within the preset physical address range applied in advance. If it is within the preset physical address range, it is considered to be legal. If it is not within the preset physical address range, it is illegal, and then it needs to be regenerated, that is, jump to the step of generating a random number again, and use the preset information digest algorithm to calculate the random number, so as to generate a new first physical address.

[0064] Step S14: configuring the first physical address to the target file node according to a preset dialing method, so that after the host reads the target file node, the first physical address is configured as the physical address of the network card.

[0065] In this embodiment, the first physical address is configured to the target file node according to the preset dialing method, so that after the host reads the target file node, the first physical address is configured as the physical address of the network card. The method of configuring the first physical address is similar to the method of configuring the second physical address, which will not be repeated here.

[0066] It can be seen that after the communication module in the present application is powered on, it determines whether there is a physical address storage file locally; if there is no physical address storage file locally, a random number is generated, and the random number is calculated using a preset information digest algorithm to generate a summary value corresponding to the random number; the summary value is intercepted to generate a first physical address, and the first physical address is written into the newly created physical address storage file; the first physical address is configured to the target file node according to the preset dialing method, so that after the host reads the target file node, the first physical address is configured as the physical address of the network card.

[0067] Beneficial effect: After the communication module in the present application is powered on, it is first necessary to determine whether there is a local physical address storage file. If not, a random number is generated, and then the random number is calculated using a preset information digest algorithm to generate a summary value corresponding to the random number. It should be noted that different data can generate a unique summary value after being processed by the preset information digest algorithm. Furthermore, the present application needs to intercept the summary value to generate a first physical address, and write the generated first physical address into the newly created physical address storage file, and then configure the first physical address to the target file node according to the preset dialing method, so that after the host reads the target file node, the first physical address is configured as the physical address of the network card. That is, the present application automatically generates and configures the physical address through random numbers and preset information digest algorithms, no longer relying on manpower, and to a certain extent also guarantees the uniqueness, certainty and security of the physical address.

[0068] See also Figure 2 As shown, the embodiment of the present application discloses a specific method for generating and configuring a physical address. Compared with the previous embodiment, this embodiment further illustrates and optimizes the technical solution. Specifically, it includes:

[0069] Step S21: After powering on, determine whether there is a local physical address storage file.

[0070] Step S22: If the physical address storage file does not exist locally, a random number is generated, and the random number is calculated using a preset information digest algorithm to generate a digest value corresponding to the random number.

[0071] Step S23: Add a target separator to the summary value according to the preset physical address format requirements to obtain an added result, and intercept a first preset number of characters from the added result to generate a first physical address, and write the first physical address to a newly created physical address storage file; wherein the first preset number is the sum of the total number of digits and the total number of separators determined according to the physical address format requirements.

[0072] In this embodiment, after the corresponding summary value is generated for the random number using the preset information digest algorithm, a target separator is first added to the summary value according to the preset physical address format requirement. First of all, it should be pointed out that the physical address format requirement usually means that the MAC address consists of 6 bytes, expressed as 12 hexadecimal numbers, and each two hexadecimal numbers are separated by a target separator, where the target separator can specifically be a colon ":" or a hyphen "-"; for example, a specific physical address format is "00:1A:C2:7B:00:47" or "00-1A-C2-7B-00-47". Therefore, in this embodiment, the target separator is first added to the summary value according to the physical address format to obtain the addition result, and the first preset number of characters is intercepted from the addition result to generate the first physical address, where the first preset number refers to the sum of the total number of digits 12 and the total number of separators 5, that is, 17.

[0073] Specifically, the above-mentioned adding a target separator to the summary value according to the preset physical address format requirements to obtain an added result includes: for the summary value, adding a target separator every two consecutive characters to obtain an added result; correspondingly, intercepting a first preset number of characters from the added result to generate a first physical address includes: starting from the first position in the added result, continuously intercepting the first preset number of characters to generate the first physical address; or, starting from the second position in the added result, continuously intercepting a third preset number of characters to obtain a first interception result, and starting from the third position in the added result, continuously intercepting a fourth preset number of characters to obtain a second interception result, and then splicing the first interception result and the second interception result to generate a first physical address; wherein the sum of the third preset number and the fourth preset number is the first preset number.

[0074] Taking the MD5 algorithm as an example, after calculating the random number through the MD5 algorithm, a hash value with a fixed length of 128 bits is obtained. This value is usually expressed in the form of 32 hexadecimal digits. Because each hexadecimal digit can represent a 4-bit binary number, 128 bits can be expressed as a 32-character hexadecimal number. Then, for the digest value, a target separator is added every two consecutive characters to obtain the addition result.

[0075] Furthermore, when a first preset number of characters are intercepted from the addition result to generate a first physical address, the first preset number of characters can be continuously intercepted from the first position in the addition result to generate the first physical address. The first position can be the starting position in the addition result or the middle position in the addition result, and then 17 characters are continuously intercepted from the position as the starting point to generate the first physical address. In addition, it is necessary to ensure that the intercepted 17 characters include 12 hexadecimal digits and 5 target separators. That is, in this embodiment, 17 characters are continuously intercepted from the addition result as the first physical address.

[0076] In addition, when intercepting a first preset number of characters from the addition result to generate a first physical address, two segments of characters can also be intercepted from the addition result respectively, and then the two segments of characters are spliced ​​to generate the first physical address. Specifically, starting from the second position in the addition result, continuously intercepting a third preset number of characters to obtain a first interception result, and starting from the third position in the addition result, continuously intercepting a fourth preset number of characters to obtain a second interception result, and then splicing the two interception results to generate a first physical address. For example, the second position can be the starting position in the addition result, and the third position can be the middle position in the addition result, and then two segments of characters are intercepted respectively and then spliced; wherein, it is necessary to ensure that the sum of the third preset number and the fourth preset number is the first preset number 17, and it is necessary to ensure that the first physical address obtained by the final splicing meets the physical address format requirements and includes 12 hexadecimal digits and 5 target separators. In addition, this embodiment does not limit the specific size of the third preset number and the fourth preset number.

[0077] It should be noted that, in addition to intercepting two segments of characters from the added result and splicing them, three or four segments can also be intercepted and then spliced. However, no matter how many segments are intercepted, it is necessary to ensure that the final first physical address includes 12 hexadecimal digits and 5 target separators and meets the physical address format requirements.

[0078] Step S24: configuring the first physical address to the target file node according to a preset dialing method, so that after the host reads the target file node, the first physical address is configured as the physical address of the network card.

[0079] For more specific processing procedures of the above steps S21, S22 and S24, reference may be made to the corresponding contents disclosed in the aforementioned embodiments, which will not be described in detail here.

[0080] It can be seen that the present application automatically generates a physical address through a random number and a preset information digest algorithm. In the specific process, after using the preset information digest algorithm to generate a corresponding digest value for the random number, the target separator is first added to the digest value according to the physical address format to obtain an addition result, and a first preset number of characters are intercepted from the addition result to generate a first physical address. The first preset number here refers to the sum of the total number of digits 12 and the total number of separators 5, that is, 17. When intercepting the first preset number of characters from the addition result to generate the first physical address, 17 characters can be continuously intercepted from the addition result as the first physical address, or several segments of characters can be intercepted from different positions of the addition result and then spliced ​​to generate the first physical address.

[0081] See also Figure 3As shown, the embodiment of the present application discloses a specific method for generating and configuring a physical address. Compared with the previous embodiment, this embodiment further illustrates and optimizes the technical solution. Specifically, it includes:

[0082] Step S31: After powering on, determine whether there is a local physical address storage file.

[0083] Step S32: If the physical address storage file does not exist locally, a random number is generated, and the random number is calculated using a preset information digest algorithm to generate a digest value corresponding to the random number.

[0084] Step S33: intercepting a second preset number of characters from the summary value to obtain a target interception result, and adding a target separator to the target interception result according to the preset physical address format requirements to generate a first physical address, and writing the first physical address to the newly created physical address storage file; wherein the second preset number is the total number of digits determined according to the physical address format requirements.

[0085] In this embodiment, after the random number is generated with the preset information digest algorithm, a second preset number of characters are first intercepted from the digest value to obtain a target interception result, where the second preset number is the total number of digits determined according to the physical address format requirements, i.e., 12. Then, a target separator is added to the target interception result according to the preset physical address format requirements to generate a first physical address.

[0086] Specifically, the above-mentioned intercepting a second preset number of characters from the summary value to obtain the target interception result includes: starting from the first position in the summary value, continuously intercepting the second preset number of characters to obtain the target interception result; or, starting from the second position in the summary value, continuously intercepting a fifth preset number of characters to obtain a third interception result, and starting from the third position in the summary value, continuously intercepting a sixth preset number of characters to obtain a fourth interception result, and then splicing the third interception result and the fourth interception result to obtain the target interception result.

[0087] Taking the MD5 algorithm as an example, after calculating the random number through the MD5 algorithm, a hash value with a fixed length of 128 bits is obtained. This value is usually expressed in the form of 32 hexadecimal digits.

[0088] Then, in a specific implementation, the first position in the digest value can be used as the starting point to continuously intercept 12 characters to obtain the target interception result. The first position can be the starting position in the digest value or the middle position in the digest value. This implementation does not limit it, as long as 12 characters can be continuously intercepted starting from the first position.

[0089] In another specific implementation, the second position in the digest value can be used as a starting point to continuously intercept a fifth preset number of characters to obtain a third interception result, and the third position in the digest value can be used as a starting point to continuously intercept a sixth preset number of characters to obtain a fourth interception result, and then the two interception results are spliced ​​to obtain a target interception result. For example, the second position can be the starting position in the digest value, and the third position can be the middle position in the digest value, and then two segments of characters are intercepted respectively and then spliced; wherein, it is necessary to ensure that the sum of the fifth preset number and the sixth preset number is the second preset number 12, and this embodiment does not limit the specific size of the third preset number and the fourth preset number.

[0090] It should be pointed out that, in addition to the above-mentioned method of cutting off two segments of characters from the digest value and then concatenating them, three or four segments can also be cut off and then concatenated.

[0091] After obtaining the target interception result, adding a target separator to the target interception result according to the preset physical address format requirement to generate the first physical address includes: for the target interception result, adding a target separator every two consecutive characters to generate the first physical address. That is, according to the physical address format requirement, adding a target separator to the target interception result every two consecutive characters to generate the first physical address.

[0092] Step S34: configuring the first physical address to the target file node according to a preset dialing method, so that after the host reads the target file node, the first physical address is configured as the physical address of the network card.

[0093] For more specific processing procedures of the above steps S31, S32 and S34, reference may be made to the corresponding contents disclosed in the above embodiments, which will not be described in detail here.

[0094] It can be seen that the present application automatically generates a physical address through a random number and a preset information digest algorithm. In the specific process, after using the preset information digest algorithm to generate a corresponding digest value for the random number, 12 characters are first intercepted from the digest value to obtain the target interception result. Among them, 12 characters can be continuously intercepted from the digest value to obtain the target interception result, and several segments of characters can be intercepted from different positions of the digest value, and then spliced ​​to obtain the target interception result. After obtaining the target interception result, a target separator is added to the target interception result every two consecutive characters according to the physical address format requirements to generate the first physical address.

[0096] (1) The communication module is connected to the host through the USB interface, and the communication module is powered on;

[0097] (2) After the module is turned on, determine whether there is a physical address storage file locally;

[0098] (3) If there is a local physical address storage file, read the second physical address in the physical address storage file and configure it to the target file node (host_addr) according to the dial-up mode rndis, specifically / sys / kernel / config / usb_gadget / g1 / functions / gsi.rndis / host_addr

[0099] (4) If the physical address storage file does not exist locally, a random number is generated through RANDOM, and the random number is calculated using the MD5 algorithm to obtain a digest value;

[0100] (5) For the digest value, search for two consecutive characters and add a colon “:” after them;

[0101] (6) intercepting the first 17 characters in the result of (5) to generate the first physical address. Under specific requirements, the intercepted 17 characters may be specially processed, for example, the second character may be replaced with 0 according to the specific needs of the user;

[0102] (7) Check the legality of the generated first physical address. If it is legal, write it into the newly created physical address storage file, and configure the first physical address to the target file node (host_addr) according to the preset dialing method, such as / sys / kernel / config / usb_gadget / g1 / functions / gsi.rndis / host_addr; if it is illegal, jump to (4) to regenerate a new random number;

[0103] (8) After the communication module enumerates the network card on the host, the host reads the physical address stored in host_addr according to the usb_gadget protocol and configures it as the physical address of the host-side network card.

[0104] This embodiment automatically generates a physical address through a random number + md5 algorithm, and this method of random number + md5 algorithm guarantees the uniqueness, certainty and security of the physical address to a certain extent; in addition, the configuration of the physical address no longer relies on manpower, and does not require personnel participation. As long as the rules are formulated, the network card on the host is automatically configured after the communication module is turned on. That is, this solution is based on this method of random number + md5 algorithm, combined with the characteristics of the usb_gadget framework, to achieve a low-cost, fully automatic, customer-unaware physical address generation and configuration solution, which improves the overall mass production efficiency and reduces costs.

[0105] See also Figure 5 As shown, the embodiment of the present application discloses a method for generating and configuring a physical address, the method comprising:

[0106] A judgment module 11 is used to judge whether there is a local physical address storage file after powering on;

[0107] A digest value generating module 12 is used to generate a random number if the physical address storage file does not exist locally, and calculate the random number using a preset information digest algorithm to generate a digest value corresponding to the random number;

[0108] An interception module 13, configured to intercept the summary value to generate a first physical address, and write the first physical address into a newly created physical address storage file;

[0109] The configuration module 14 is used to configure the first physical address to the target file node according to a preset dialing method, so that after the host reads the target file node, the first physical address is configured as the physical address of the network card.

[0110] It can be seen that after the communication module in the present application is powered on, it determines whether there is a physical address storage file locally; if there is no physical address storage file locally, a random number is generated, and the random number is calculated using a preset information digest algorithm to generate a summary value corresponding to the random number; the summary value is intercepted to generate a first physical address, and the first physical address is written into the newly created physical address storage file; the first physical address is configured to the target file node according to the preset dialing method, so that after the host reads the target file node, the first physical address is configured as the physical address of the network card.

[0111] Beneficial effect: After the communication module in the present application is powered on, it is first necessary to determine whether there is a local physical address storage file. If not, a random number is generated, and then the random number is calculated using a preset information digest algorithm to generate a summary value corresponding to the random number. It should be noted that different data can generate a unique summary value after being processed by the preset information digest algorithm. Furthermore, the present application needs to intercept the summary value to generate a first physical address, and write the generated first physical address into the newly created physical address storage file, and then configure the first physical address to the target file node according to the preset dialing method, so that after the host reads the target file node, the first physical address is configured as the physical address of the network card. That is, the present application automatically generates and configures the physical address through random numbers and preset information digest algorithms, no longer relying on manpower, and to a certain extent also guarantees the uniqueness, certainty and security of the physical address.
